1. General Information
Description
Theory of Operation
This document describes the procedures required to install, operate, maintain, and troubleshoot the Model GF03 Flowmeter. There are a wide range of possible configurations and information related to the optional features. The flowmeter is composed of a remote thermal dispersion sensing transducer (flow element) connected to a microprocessor-based electronics control and display package (flow transmitter). The flow element is attached to the flow transmitter thru a cable of up to 1000 feet or 300 meters (remote instrument).
The instrument is designed to operate in gaseous flow metering environments. The flowmeter is factory calibrated to handle a range of flows.
The primary flow element consists of two thermowells of the same size, shape and mass. One thermowell contains a platinum RTD and a heater element. The other contains one RTD. The RTD located with the heater element is called the active RTD. The other RTD is referred to as the reference RTD. Since the active RTD is embeded in the heater, the temperature of the active thermowell is always above the temperature of the process media. The temperature at the reference RTD is the temperature of the process media. When the process media is flowing past the active RTD a quantity of heat is carried off into the flow stream. The amount of heat taken from the active RTD is a function of the process media mass flow rate. A ∆T (temperature) exists between the two thermowells and a proportional ∆R (ohms resistance) exists between the active and the reference RTDs. The ∆R is measured by the flow transmitter. The relationship of ∆R to the calibrated flow rate is calculated by the flow transmitter and is converted into both analog and digital outputs.
The Gas Compensation element provides a ∆R value similar to the primary flow element. This value is a no-flow ∆R based on the thermo physical properties of the gas mixture minus any flow component. This value is used to correct gas composition changes in the Transmitter microprocessor.
Sensing Element
The standard sensing element is an all welded 316L stainless steel insertion probe. The element consists of the primary flow element located on the end of the probe and the compensator element located in the insertion pipe. The optional Veri-Cal inlet tube runs the length of the insertion pipe exiting into the base of the primary flow element. This tube allows the Veri-Cal system to distribute a repeatable flow rate on the primary flow element
for calibration verification purposes.

FLUID COMPONENTS INTERNATIONAL LLC http://www.fluidcomponents.com
Flow Transmitter
The other component of the flowmeter is the flow transmitter. The basic functions of the flow transmitter are to provide power to the flow element, measure the Differential Temperature (∆T) between the two RTDs as a function of resistance, amplify and linearize the Differential Resistance (∆R) measurement of the flow element and provide a proportional output signal.
This output signal is calibrated to the flow rate as a function of standard velocity or volume. To perform these functions, microprocessor-based electronic circuitry is employed to acquire the analog voltage signals from the RTDs, digitize and interpret the information.
The microprocessor-based electronics provides maximum flexibility and ease of operations with a menu-driven selection of control, monitoring, display and driver options.

2. Installation
Receiving / Inspection
Packing / Shipping and Returns
Factory Calibration Note
Pre-Installation Procedure
w Unpack carefully, observe Electro-Static Discharge (ESD) precautions if handling the
flow transmitter.
w Inspect for damage to the flow element and the flow transmitter. w Verify that all items in the packing list were received and are correct. w Verify the Delta R Data Sheet and the Instrument Information Sheet are present.
If the above items are satisfactory then proceed with installation. If not, then stop and contact the FCI customer service representative for instructions.
These issues are addressed in Appendix C - Customer Service.
The flowmeter is factory calibrated to the flow range specified in the order. There is no need to perform any verification or calibration steps prior to installing and placing the flowmeter in service.
Caution:
The flow transmitter contains electrostatic discharge (ESD) sensitive
devices. Use standard ESD precautions when handling the flow transmitter. See below for ESD details.
The GF Series Flowmeter is not designed for weld-in-place applications. Never
weld into the installation or to a structural support.
Use Standard ESD Precautions
Use standard ESD precautions when opening an instrument enclosure or handling the flow transmitter. FCI recommends the use of the following precautions: Use a wrist band or heel strap with a 1 megohm resistor connected to ground. If the instrument is in a shop setting there should be static conductive mats on the work table and floor with a 1 megohm resistor connected to ground. Connect the instrument to ground. Apply antistatic agents to hand tools to be used on the instrument. Keep high static producing items away from the instrument such as non-ESD aproved plastic, tape and packing foam.
Prepare or Verify Flow Element Location
Prepare the media process pipe for installation or inspect the already prepared location to ensure the instrument will fit into system. Prepare the necessary sealants or gaskets to provide a leak proof installation.
The U-length should be double checked when installing the flow element into the process media. The U-length is determined at the factory order time and is the distance that places the flow element head center line in the center line of process media. See Figure 3. The greatest accuracy is achieved when the flow element is mounted at least 20 diameters downstream and 10 diameters upstream from any bends or interference in the process pipe or duct.
Doc. No. 06EN003352 Rev. B 5 Model GF03 Flow Meter
FLUID COMPONENTS INTERNATIONAL LLC http://www.fluidcomponents.com
Verify Serial Numbers
Verify the flow element and flow transmitter have the same serial number, as they are to be installed as a matched set.
Verify Dimensions
Verify the flow element and flow transmitter dimensions as shown in Appendix A.
Verify Flow Direction for Flow Element Orientation and Placement Note: Correct flow element placement in the measurement stream is vital for obtaining
accurate flow readings. Before mounting the flow element, check the options ordered for correct orientation and insertion length at the planned site of installation.
The flow element thermowells must be positioned in the same orientation to the process flow as they were during calibration (refer to the Instrument Information Sheet). Failing to install the flow element correctly may reduce the accuracy of the flowmeter. Be sure the flow arrow points in the direction of flow.
The flow element thermowells are to be placed as shown in Figure 3, with the end of the shroud 0.6 inches past center line.
There is a flat area machined perpendicular to the thermowell plane. Adjust the flow ele­ment during installation so the flat area is parallel, with in ±2°, to the direction of process media flow.
Adjustable / Retractable Flow Element Assembly
Caution: Do not over-tighten the flow element. The RTD's can be
dammaged if the flow element is forced into the far wall of the pipe or vessel.
Select one of the following installation procedures which is applicable to the unit being installed.
NPT and flange packing gland mounts are available. The valve assembly with appropriate connections are typically customer supplied. Follow the pipe or flange mounting procedure below.
NPT Pipe Mounting
w Apply sealant compatible with the process media to male threads. Carefully insert into
process mount. Threads are right-handed. Tighten with an open-end wrench on the hexagonal surface provided. Rotate until snug.
Figure 3 - NPT Pipe Mount
Model GF03 Flow Meter 6 Doc. No. 06EN003352 Rev. B
FLUID COMPONENTS INTERNATIONAL LLC http://www.fluidcomponents.com
Flange Mounting
w Attach the process mating flange with care. The correct orientation of the flow element
must be maintained to ensure the calibrated accuracy.
w Verify that the process media flow is in the same direction as the arrow on the FLAT. w Apply the appropriate gasket and/or sealant to flange mount as required. w Mate flow element flange to process mount keeping flat oriented properly. w Attach with bolt, two flat washers, lock washer and nut for each bolt hole, apply lubricant/
sealant to male threads and torque. Refer to ANISI B16.5 specifications.
General Mounting
w Tighten packing nut until internal packing is tight enough so that the friction fit on the
shaft is adequate to prevent leakage but not prevent the shaft from sliding. Position the flat horizontal with arrow in direction of process flow.
w Proceed to insert the flow element into process media line. For the medium pressure
packing gland use the adjusting nuts on the all-thread to pull the flow element into proper predetermined depth position.
w Tighten the opposing lock nuts on the all-threads. Tighten the packing nut another 1/2
to 1 turn until tight (approximately 65 to 85 ft-lbs torque).
w Rotate split ring locking collar to line up with connecting strap welded to packing nut.
Tighten the two 1/4-28 hex socket cap screws on the split ring locking collar. Open valve
- check for process media leakage.
w Reverse these steps for removal.

Install Transmitter
Warning: Installation of an FCI instrument should only be performed by properly trained
personnel in accordance with the current edition of the National Electrical Code. Ensure that all power is off. Any instances where power should be applied to the instrument will be noted in this manual. Where the instructions call for the use of electrical current, the operator assumes all responsibility for conformance to safety standards and practices.
Caution: In applications where the flow element is located in an explosive environment,
isolate the conduit before it leaves the environment. A potting "Y" may be used to provide the isolation.
Remote Hardware
See Appendix A for the remote enclosure along with the physical dimensions so the flow transmitter can be properly mounted.
Note: The factory recommends removal of the transmitter while pulling the necessary
cables; this will prevent damaging the circuit boards or their components. To remove the transmitter unbolt the four outermost screws on the transmitter mounting plate.
Power Connection Information Conduit Routing
All electrical connections are to be made through the female NPT openings in the flow transmitter's enclosure. FCI strongly recommends that all electrical cables be run through an appropriate conduit for the protection of the instrument and personnel. Refer to the appropriate wiring diagram.
Protection of the electronics from moisture is an important consideration. Keep the entry of the conduit into the enclosures in the downward direction so condensed moisture that collects in the conduit will not drain into the enclosure. In addition, FCI recommends sealing off the conduit with a potting Y or other sealing method to prevent moisture from entering the enclosure.
Minimum Wire Size
Table 1 shows the smallest (maximum AWG number) copper wire which should be used in the electrical cables. Use a lower gauge of wire for less of a voltage drop. Contact FCI concerning greater distances than those listed in the chart.

FLUID COMPONENTS INTERNATIONAL LLC http://www.fluidcomponents.com
Input Power
The flow transmitter is powered by 115 VAC, 230 VAC or 24VDC (only one power source is needed). If 115 VAC is used, wire it directly to JP8 and position switch S1 to be in the 115V position. If 230 VAC is used, position switch S1 to be in the 230V position and then wire the power directly to JP8. If 24 VDC is used, it is wired directly to JP8 as shown on the wiring diagram.
The installation of an AC line disconnect switch (and possibly a fuse) between the power source and the flowmeter is strongly recommended. This facilitates easy power disconnection during calibration and maintenance procedures as well as an added safety feature.
Remote Transmitter
Route all interconnecting wiring into the remote transmitter enclosure. Ensure wires are long enough with sufficient service loops to eliminate excessive strain on the terminal connections. Connect Flow and Analyzer element cables as shown on wiring diagram. The display orientation varies for different transmitter configurations, but the termination block for the element connection remains the same. If the Veri-Cal option was ordered, wire the pressure transducer as shown on the wiring diagram.

3. Operation
Introduction
Start Up Procedure

Operation

The flowmeter has been configured and calibrated to custom specifications. Each flowmeter contains distinct operating limits and units of measurement. This chapter will show how to determine and manipulate the configuration of the flowmeter.
1. After the wiring has been verified, apply power to the flowmeter. (No special instructions for instrument shutdown; turn operating power off.)
2. Then wait 10 minutes for warm-up. During this period the flowmeter may indicate high flow.
3. After power up the instrument automatically enters the flow metering mode and the display sets to normal operation.
Display
The flowmeter contains a 4 x 20 character LCD display. Flow rate, temperature, and system status are all accessible through the display.
Initialization Window
When power is applied to the flowmeter the display will briefly show the initialization window. See Figure 8.

Menu Window
The menu is made up of 4 components. They are the menu level, title, selections, and prompt line. These components are illustrated in Figure 10. The top line displays a menu code and title. Lines 2 and 3 are used to scroll through the available selections. The prompt line indicates which menu commands are appropriate.

Figure 10 - Menu Window
The menu code is a numeric reference that identifies each window of the menu structure. The menu code in Figure 10 indicates that the user is two levels deep (Level 2, sublevel 1). The menu structure will be explained further in Menu Organization.
The title gives the user a better idea of where the system is within the menu structure. Some titles are informative enough to completely describe the menu function, while other titles are ambiguous unless there is knowledge of the parent menus.
The middle two lines display the available selection. The number of choices is often more than the two displayed. Pressing the N (next) or P (previous) keys on the keypad will scroll the selections up or down. To choose a function from the available selections press the corresponding number on the keypad.
The prompt line displays appropriate menu control key strokes for that menu level. Pressing N, the (N)ext key, will scroll the display down. Pressing P, the (P)rv or Previous key, will scroll the display up. Pressing the UP key shifts the current menu level up one. Pressing the HOME key goes straight to the 0.0 MAIN MENU.
Other Window Types
Another common window encountered is shown in Figure 11. The window is similar to the Menu Window except that it does not scroll and all choices are contained within the window. The current selection (if there is one) is also contained in the parenthesis to the left of the question mark.

See Table 3 for key pad assignments. At any time, the HOME key can be pressed and the main menu will display. HOME can be used to escape from most routines, restart a progression into the menu structure, or quickly change from one area of the menu to another.
When (N)ext is displayed on the prompt line, more than two menu selections are available. Press N to scroll through all the selections.
The UP key, will back-out of a menu level. The menu moves back one level each time the UP key is pressed. The UP key only functions when UP is displayed on the prompt line.
To make a selection, press the numeric key associated with the desired menu selection. The selection does not have to be displayed, but it must be one of the available selections.
Every path through the menu will eventually cause control to pass from the menu structure to a routine that performs a task such as change a parameter value, initiate a test, or calibrate the system hardware. When the system is operating outside the menu structure, there are subtle differences in the user interface. For example, the UP key may have no affect or the prompt line won't appear.

Configuring the Flowmeter
There are several parameters that can be modified to customize the system. This section describes how the flowmeter can be customized to best fit requirements.
Password Protection
Before the flowmeter configuration is customized, access to the system parameters must be gained. Two levels of password protection affect access to these parameters. w Factory Level
The highest level of protection requires a system password for access. This password prevents the user from inadvertently changing variables associated with the system calibration or other parameters that require factory resources to properly set.
w User Level
The second level of protection requires a user password for access. This password provides the user with the ability to limit access to parameters that affect the way the system operates. The default user password is 123 and can be changed to any combination of up to 12 characters in length.
Both levels of password protection can be enabled or disabled. When the system leaves the factory, the factory level and user passwords are enabled. No password is required to enable a level of protection, but the appropriate password is required to disable protection.
NOTE:
w To edit the user password:
1. From the Main Menu press 4. The 4.0 MISCELLANEOUS menu title will appear.
2. Press 3, Password Setup.
3. Press 2, Edit Password.
4. If password protection is enabled enter the current password.
5. Enter the new password of up to 12 characters.
6. When prompted to Save Permanently enter Y for yes.
The user password is set to 123 when the system is shipped.
Selecting Units of Measure
w To enable and disable the password protection:
1. From the Main Menu press 4. The 4.0 MISCELLANEOUS menu title will appear.
2. Press 3, Password Setup.
3. Press 1, Enable/Disable Password.
4. Enter the user password if prompted to do so.
5. The password protection will be toggled on or off depending on its previous state.
The flowmeter measures the flow rate and stream temperature of the process media. The display can be set to present the flow rate and temperature in a variety of units. The factory will set the units of measure to those specified at order entry time. There are other units of measure that can be chosen. Two units that will appear are m and mm. The letter m stands for 1000 and mm stands for 10,000. Menu level 3.1 provides the options for changing the output units of measure. The units of measure can be selected for temperature at menu level 3.2. The units of measure for the totalizer are available at menu level 3.3.
NOTE:
By answering the prompt, Save permanently?, with a N or by pressing the HOME key, the flowmeter will revert to the previously saved units of measure when the power is cycled.

Setting Analog Outputs
The flowmeter has two, independent analog signal outputs. The outputs can be set to represent flow rate or temperature. The flowmeter signal outputs have been configured according to the application information supplied to the factory at the time of order. However, the outputs can be re-scaled anywhere within the calibrated flow range. The ouputs can be independently set to one of the four ranges: 4 to 20 mA, 0 to 5 V, 0 to 10 V, or 1 to 5 V. A typical configuration is presented in Table 7.
The signal range varies linearly with change in flow rate as shown in Figure 14. Minimum
Port No. Mode Type Zero Full-Scale (F.S.)
1 4 to 20mA Flow 0 SF/S 150 SF/S 2 4 to 20mA Temp -50°F 150°F
Table 7 - Typical Signal Output Configuration
signal output can be set to indicate a flow of zero. This is often referred to as a zero-based signal output. A minimum signal that represents a value greater than zero is referred to as non­zero based.
Figure 14 - Signal Output versus Flow Rate
NOTE: The flowmeter inherently has a minimum, non-zero flow rate that it is able to
detect. Therefore, setting the minimum signal output (referred to as Zero in Menu
2.1.1) to zero will create a step in the output. This step corresponds to the flow where the flowmeter begins accurate measurement. Turndown ratios ( turndown is defined as the maximum flow rate divided by the minimum flow rate) smaller than 10:1 will have a large step change thus reducing the usable signal range.

The remainder of this chapter contains topics that may not be applicable to every user of the flowmeter. In most cases the flowmeter will be ready for use straight out of the box. However, there may be an application where the advanced features of the flowmeter may be needed. This section discusses how to correct for bias errors due to non-ideal installations, how to communicate with the flowmeter through the serial port, and how to use the multiple calibration options.
Flow Rate Correction Equation
The flow rate correction equation or corrector is used to bias the flow rate output. The correction equation contained in the flowmeter allows the user to correct for bias errors due to non-ideal installation effects. The correction equation is applied to the measured flow rate and then this corrected flow rate is used to drive the analog outputs and manipulate the relays. The flow rate shown on the display is also the corrected value. Figure 20 describes how the correction equation is applied.
The correction equation for the flowmeter is shown below.

The Auxiliary Input
The flowmeter has one analog signal input port that can be used to directly manipulate the flow rate output. This signal input port is called the auxiliary input. The signal measured by the flowmeter allows for the correction of errors that may be caused by changes such as process composition. The factory has determined from the application data supplied at the time of order whether the flowmeter would benefit from using the auxiliary input. If the auxiliary input is not used in the flowmeter the following section can be skipped. If the auxiliary input is used, all the internal settings necessary have been entered into the flowmeter. The following is a description of the internal and external workings of the auxiliary input.
w To determine if the flowmeter is set to use the auxiliary input:
1. From the Main menu press 2. The 2.0 PORT SETUP menu title will appear.
2. Press 4, the Aux Input option.
3. Press 2, the Enter Aux option. Enter the user password (if it is enabled).
4. Press 5, the Verify option. The variables AUX 1, 2 and 3 will appear.
5. Press ENTR and DISABLED or ENABLED will be on the third line. If ENABLED is displayed then the flowmeter has been configured to use the auxiliary input.
The auxiliary input is accessed at terminal JP6 located on the lower circuit board. Figure 22 illustrates the auxiliary input connected to a current source. If OUT 1 COM is not easily accessible then use JP6 OUT 2 COM, JP7 GND, JP1 DC GND OR JP3 GND. They are electrically the same signal ground point. The range of this source is most likely 4-20mA.

calculate a factor that is multiplied by the measured flow rate. The factor is calculated using the following relationship:
KA = A1 + (A2 x s) + (A3 s2) + (A4 x s) where s = Digital Value
Ai = Correction Factor Coefficients ( i = 1 through 4 ) KA = Correction Factor
NOTE: Ai is used for clarity in the manual. The flowmeter uses Fj as the Correction Factor
Coefficient.
The Auxiliary Input Equation coefficients are determined by the factory from the data supplied at the time of order entry.

Serial Communications
The flowmeter has one RS-232 port. The data stream is sent at a rate of 9600 baud with no parity, 8 bit characters and 1 stop bit. The baud rate is fixed and cannot be changed. All operations accessible through the keypad are also available through the serial port. The serial port, designated as JP3, is located on the lower right corner of the upper circuit board. The connection is a RJ-11 phone jack. Figure 24 represents the connection between the serial port and the host device. A serial communications kit containing adapter plugs are available from FCI for both the DB­9 and DB-25 connectors which allow the use of standard 6 wire phone line cord between the RJ-11 serial port and the host device. The order number for the DB-9 Connector kit is 014108-
01. Serial communication software is provided with each connector.
NOTE: The standard phone line used must be a reversing type and not a straight-through
type of cable.

The serial port input/output stream duplicates the actions of the keypad and the LCD display. Commands sent through the serial port to manipulate the flowmeter are exactly equivalent to the keypad sequences. Data coming out of the serial port is equivalent to the data sent to the display. Remote communication with the flowmeter consists of character sequences that duplicate actions taken at the keypad. For example, the string H 2 4 2 5 produces the same results as pressing HOME, 2, 4, 2, 5 from the keypad. Figure 25 is an example of code written in Quick Basic that extracts the flow rate and the temperature through the serial port.
A common communication problem is over writing flowmeter serial buffer. If the buffer is overwritten the last characters sent are lost. If the flowmeter does not respond as expected to a command, slow down the data flow from the user PC or control device.

The flowmeter is calibrated at the factory in a test stand that duplicates or models the customer application. The calibration process produces the information needed to relate RTD signal to an actual mass flow rate. That calibration information is entered into the flowmeter. Information about the customer's process such as pipe inside diameter and the process standard density is also entered. Situations exist where a pipe or duct may have two or more distinct process flow streams or the flowmeter needs to be used in more than one installation. The flowmeter can accommodate three sets of calibration information, therefore it can be used to monitor multiple flow streams or used in multiple installations. Each set of calibration information is called a Group. The factory has determined from the application data supplied at the time of order whether the flowmeter would benefit from using multiple Groups . If multiple Groups are not used in the flowmeter the following section can be skipped. If multiple Groups are used, all the information necessary has been entered into the flowmeter. However, the method and conditions that determine the current Group can be altered.
w To determine if the flowmeter is set to use the Multiple Groups:
From the Main menu press 1. The flowmeter will enter the normal mode of operation. If the mode on the last line of the window (see Figure 9) is Auto, or Link then the flowmeter contains multiple calibration groups.
If the mode is normal or Norm is displayed in the normal operation window, the flowmeter may still contain multiple calibration groups.
Doc. No. 06EN003352 Rev. B 33 Model GF03 Flow Meter
FLUID COMPONENTS INTERNATIONAL LLC http://www.fluidcomponents.com
w To determine if the flowmeter is set to use the Multiple Groups in Normal
mode:
1. Press 4, the Miscellaneous option.
2. Press 1, the Set Group option.
2. Press 1 again, the Set Group option. Enter the user password (if it is enabled).
3. Press 2, to change the current group to Group 2.
4. Press HOME, 7, 3 and 8. Scroll the display to show C1 to C5. If the coefficients C1 through C5 are non-zero values, the Flowmeter has been set to use multiple groups.
5. Change the current group in Set Group back to group 1.
Switching Groups Through the Keypad
Switching Groups Through the Serial Port
Switching Groups by Temperature - Auto Selecting
The current calibration group that the flowmeter uses can be changed from the keypad. This may be the most desirable method of changing groups for a flowmeter that has been configured for multiple installations.
w To change the current group from the keypad:
1. Press 4, the Set Group option.
2. Press 1, the Set Group option. Enter the user password (if it is enabled).
3. Enter the desired group number, 1, 2 or 3. The flowmeter is now set to use that group of calibration information.
The current calibration group can be changed remotely through the serial port. The sequence of commands sent through the serial port is equivalent to the sequence taken at the keypad. The command string should include sufficient time delays to allow the flowmeter to respond. One possible command string is "H H 4 1 1" + (desired group number) + "H 1". The command string sends to HOME (H) characters, sets the menu level to 4.1.1, enters the desired group number and returns the flowmeter to normal operation. Remember to insert a time delay after sending each character. (See Figure 25 for an serial communication example.)
The flowmeter has the ability to switch groups on changes in process temperature or changes in signal into the auxiliary port. To use the auto-select option, the flowmeter must be configured by the factory. Use the procedure described in the section Multiple Groups to determine if the flowmeter has been configured to use multiple groups. In Auto-Select mode the user can program the flowmeter to switch on temperature. One temperature switch point is used for switching between two groups and two switch points are used for three groups. The switch points have a 2.5% hysteresis and cannot be changed. A typical application that would benefit from using auto-selecting by temperature is described in Figure 26.

The flowmeter would be calibrated in both nitrogen and the process gas, then the information would be stored in Group 1 and 2. An auto-select temperature switch point of 150 °F would allow the flowmeter to toggle automatically between nitrogen and the process gas when the switch point is crossed. If requested, the factory, will configure the flowmeter for the Auto­Select mode from the application information supplied at the time of the order. Generally, there will be no need to change the settings, however, the switch point values can be adjusted if necessary.
w To enter a new temperature switch point(s) for the Auto-Select mode:
1. Press 4, the Miscellaneous option.
2. Press 1, the Set Group option.
2. Press 2, the Set Auto-Select option.
3. Press 2, the By Temperature option. Enter the user password (if it is enabled).
4. Enter the number groups involved in the Auto-Selecting. (Zero to disable.)
5. Enter the switch point temperature(s).
NOTE: The minimum and maximum temperatures for adjacent Groups must be
separated by a least 20°F (11°C).
w To enable or disable the Auto-Select mode:
1. Press 4, the Miscellaneous option.
2. Press 1, the Set Group option.
3. Press 3, the Enable Auto-Select option. Auto-Select will toggle on or off depending on its previous state. Enter the user password (if it is enabled).
Link Groups (Extended Range Emulation)
NOTE: When changing system parameters such as flow rate units the Auto-Select
mode must be turned off.
The Link Groups option enables the flowmeter to measure flow ranges of greater than 100:1 to up to 1000:1. (Turndown is defined as the maximum flow rate divided by the minimum flow rate.) This function is similar to the LT Series Extended Range. Links Groups can only be set by the factory. The Link Groups mode operates transparently (as if the flowmeter were operating in normal mode), although, when changing system parameters there are a few extra steps that need to be taken.
w To determine if the flowmeter is in Link Groups mode:
Press 1, the Normal Operation option. The mode of operation is displayed on the last line. Link is displayed if the link groups option is enabled.
If the flowmeter's link groups option is enabled, then changes in system parameters must be made for each group. For instance, if the flow rate units are changed, the flow rate units for each linked group must be changed.
w To change system parameters in Link Groups mode:
1. Press 5, the Verify option.
2. Press 8. Scroll the display to the fourth window. The Link Groups mode is displayed on the third line.
3. Press Home, 7, 3 and 7, the Link Groups option. Enter 9 4 2 to enable the function.
4. Press 4 to disable the Link Groups option.
5. Make the parameter changes for all groups, switching between groups using the Set Group option, 4.1.1.
6. Re-Link Groups from menu level 7.3.7 by repeating step 3. Reset the link to the prior setting.
NOTE: The link groups (extended range) and auto-select modes cannot be used

Calibration Functions Menu 7.0
Veri-Cal In-Situ Calibration Verification
The calibration functions of the flowmeter are contained in menu level 7.0. These functions are not needed for general operation and setup of the flowmeter. With the exception of 7.1, Show Delta R, these functions should be used only after consultation with a factory service representative. Menu level 7.1 displays the RTD resistances and can be compared to calibration resistances. This is useful for troubleshooting problems and is addressed in Chapter 5, Troubleshooting.
w To view RTD resistance values:
1. Press 7, the Calibration option.
2. Press 1, the Show Delta R option.
The GF03 has an optional Veri-Cal system that allows the user to check, or verify, the instruments calibration without removing the flow element from the process installation. The diagram below shows the Veri-Cal system.
Figure 28 - Veri-Cal System
The system consists of the Transmitter assembly, GF03 flow element with internal Veri-Cal flow system, the Veri-Cal regulator assembly and interconnecting hose.
The Veri-cal flow system delivers a repeatable flow through a nozzle across the primary flow element thermowells. This is done while the flow element is retracted out of the process flow stream into the insertion packing gland assembly. The flow element orientation is leveled. An inert gas controlled through a precision regulator on the inlet side of a sonic nozzle is then injected across the thermowells. The factory calibration gas is typically Nitrogen, but other gases maybe used.
Validation Check Procedure:
FCI recommends that this procedure be run at the Instruments commissioning to determine an initial installed baseline verification calibration, and to record any installed offset from the factory Veri-cal Basline.
1. Loosen the packing nut assembly until the internal packing is lose enough to allow the probe assembly to be retracted completly back into the insertion pipe assembly.
2. Level orientation flat and tighten packing nut so probe assembly is secure.
Model GF03 Flow Meter 36 Doc. No. 06EN003352 Rev. B
FLUID COMPONENTS INTERNATIONAL LLC http://www.fluidcomponents.com
3. Verify that the ball valve on the probe assembly is closed. Remove the end cap and
attach the interconnecting hose and regulator assembly.
4. Attach the calibration gas source to the inlet side of the regulator assembly.
5. Slowly open the gas source regulator until the analog gauge in the Veri-cal regulator
assembly reads 125 psig, no gas should be flowing through the instrument at this time.
6. Verify that the system is leak free.
7. Obtain local atmospheric pressure. Look at the GF03 Veri-Cal calibration sheet and
calculate the pressure offset from the local atmospheric pressure and calibrated atmospheric pressure.
Calibrated atm press – Local atm press = pressure offset
Add this offset to the Veri-Cal Baseline indicated pressure values in column 1 on the calibration sheet to determine verification indicated pressure check values.
For example, if the calculated pressure offset is 1.40 psi and the first baseline indicated pressure is 100 psig. The first verification check value of 101.40 should be dialed into the Pressure displayed on the Transmitter display.
8. Enter the Veri-cal menu on the Transmitter assembly (menu 7.4) Flow, Temperature and
Pressure will be displayed.
9. Open the ball valve on the probe assembly and adjust the regulator so that the Pressure
display on the Transmitter display equals the first verification check value (101.40 in the example).
10. Sustain this flow rate for 5 minutes to allow the instrument to come to thermal equilibrium.
11. Record the Indicated Flow, Temperature and Pressure.
12. Repeat this procedure for the remaining 3 indicated pressure check values. A consistent
flow across the thermowell should be held for a minimum of 5 minutes before values are recorded.
13. Record all values on the Veri-cal calibration sheet for reference and comparison during
the next in-situ verification check. An example of the calibration sheet is shown below.

4. Maintenance
Warning: To avoid hazards to personnel, ensure that all environmental isolation seals are
properly maintained.
Introduction

Maintenance

The flowmeter needs very little maintenance. There are no moving parts or mechanical parts subject to wear in the flowmeter. The flow element that is exposed to the process media is all stainless steel construction with nickel braze. The flow element is only subject to chemical attack based on the corrosion relationship between the flow element sensing point material and process media.
No specific maintenance steps are made for inspecting, cleaning, or testing procedures without detailed knowledge of the process media components. However, shown below are some general guidelines for maintenance. Use operating experience to set the frequency for each type of maintenance.
Calibration - Every 18 months as a minimum, verify the calibration of the flowmeter and re­calibrate if necessary (contact the factory).
Electrical Connections - Periodically inspect the cable connections, the terminal strips and the terminal blocks for good connections. Verify that terminal connections are tight and physically sound with no sign of corrosion.
Enclosures - Verify that the moisture barriers and seals that protect the local and remote enclosures are in tact.
Electrical Cables - Periodically inspect the power cable, flow element cable(s) and output cable. Check for deterioration of the cable's insulation.
Flow Element Mounting Connections - Verify that all seals are performing properly and that there is no leakage of the process media. Check for deterioration of the gaskets and environmental seals used.
Flow Element Assembly - Periodically remove the flow element for inspection based on historical evidence of debris, foreign matter, or scale build-up. Also the flow element can be removed at appropriate plant shutdown schedules. Check for corrosion, stress cracking, and/or build-up of oxides, salts, or foreign substances. The thermowells must be free of excessive contaminants and be physically intact. Any build-up could cause faulty readings. Clean the flow element as needed with a soft brush and available solvents (compatible with stainless steel).

5. Troubleshooting
Introduction
Warning:
Only qualified personnel should attempt to test this instrument. The operator assumes all responsibilities for safe practices while troubleshooting.
Caution:
The flow transmitter contains electrostatic discharge (ESD) sensitive devices. Use standard ESD precautions when handling the flow transmitter. See Chapter 2, Installation, for ESD details.
In new or re-calibrated instruments, operating problems are most often caused by an improper installation. Review the information on instrument installation in Chapter 2 to verify correct mechanical and electrical installation.
Troubleshooting is more effective if the operation of the equipment is understood before trying to solve the equipment problems. Be familiar with the way the instrument operates (Chapter 3) before troubleshooting an instrument that does not function properly.
Replacement parts must be of the same part type and number. Therefore, contact the FCI Customer Service Department for the correct replacement parts.
Damage to the equipment due to negligence or lack of technician skill is not covered by the warranty, or is damage to flow transmitter caused by part replacement in the field. When parts are replaced, the verification and calibration procedures should be performed by a qualified technician to ensure the accuracy and calibration of the instrument.
Troubleshooting Equipment
Quick Check Troubleshooting
Digital Multi-Meter (DMM) (at least 4 1/2 digits resolution recommended) capable of measuring ohms, milliamperes, and volts AC and DC.
Precision decade resistance boxes (two needed, however they are optional).
At this point simply observe the system setup to verify operation. Use Table 8 as a quick check of problems and solutions. More in-depth discussions follow this table.
Problem Solution
1) Check the fuses.
2) Verify that S1 is switched to the correct input voltage
No Display
No Display or Dim Display
Display is Locked Up
Readings Seem Incorrect
3) Verify correct power is applied.
4) Verify the ribbon cable between the upper and lower circuit boards is solidly connected and the red stripe is at pin 1.
Adjust potentiometer R1 on the top circuit card. If there is no change in the display return the potentiometer to the original setting.
Press HOME and then 1 to return to normal operation. Reset the flowmeter by cycling the power.
Verify the serial number of the flow element and the flow transmitter are the same number.
Verify the flat on the flow element is parallel to the pipe and the flow arrow is pointed in the direction of the flow stream.
S2 switches should all be closed for an integral (local) instrument and all open for a remote instrument.
Verify all jacks and plugs are firmly seated and the wiring to them is secure.
If the above solutions do not correct the problem, continue to use the rest of this chapter to troubleshoot.

In-Depth Troubleshooting The Flow Element
Check Serial Numbers
Verify that the serial number of the flow element and the flow transmitter are the same. The flow element and the flow transmitter are a matched set and cannot be operated independently of each other. The only exception is when the flow transmitter has been specifically configured to be a replacement.
Check the Resistance of the Flow Element
Use Tables 9 and 10 to determine if the flow element is wired incorrectly or has failed. Turn off the input power to the transmitter. Unplug the flow element at JP3 located on the lower board and measure resistances described below by touching the DMM test leads to the JP3 terminal screws. (Remember to reconnect JP3 back to the flow transmitter when finished.) Repeat resistance check on TS2.
NOTE: If the system does not allow the disconnection of the flowmeter power, or
unplugging the flow element, then proceed to the section, "In-Depth Troubleshooting - The Flow Transmitter".
All resistances in Tables 9 and 10 are based on a temperature of 32°F (0 °C). Resistances acrosst the ACT and the REF RTD’s are approximately 1080 ohms* at 70 °F ( 21 °C ). The resistances will continue to increase for higher temperatures at the flow element. Check resistance from each pin in the local/remote enclosure to case ground. There should be an infinite resistance.
Pin Number Approximate Resistance
1 to 2 0 Ohms 2 to 3 1000 Ohms 2 to 4 1000 Ohms 2 to 5 1000 Ohms 2 to 6 1000 Ohms 2 to 7 115 Ohms

7 to 8 110 – 118 Ohms
Table 10 - Resistance at TS2
Compensator Elemenet
Primary Flow Element
If the measured resistances do not correspond to Tables 9 and 10 then the flow element is functioning properly. The problem lies else where. Skip the rest of this section and proceed with the section, In-Depth Troubleshooting - The flow transmitter. If the measured values do not correspond to Table 5-2 then a problem exists in the flow element. For remote instruments, with a cable between the flow element and the flow transmitter, the cable could be shorted or open. To isolate a problem with the cable, check the flow element resistances at the terminal block located within the flow element (local) enclosure. Disconnect the wires from the terminal block and measure resistances described below by touching the DMM test leads to the terminal block screws. The measured resistances should correspond approximately to the values in Table 5-3.
If the measured resistances correspond to Table 5-3 then the cable or wiring is defective. Contact customer service for details on how to obtain another cable or flow element.

FLUID COMPONENTS INTERNATIONAL LLC http://www.fluidcomponents.com
In-Depth Troubleshooting The Flow Transmitter
Check the Voltages Across the RTD Leads
This is done without disconnecting any flow element wires. Voltage measurements can be made at JP3 located on the lower circuit board. Measure voltages described below by touching the DMM test leads to the terminal screws. The expected voltages are given in Table 12.
Table 12
Voltage Readings in Volts DC at JP3
Pin Number Approximate Voltage
1 to 2 0 2 to 3 1.1 2 to 4 1.2 2 to 5 1.1 2 to 6 1.2 2 to 7 16.5
If the measured voltages correspond to Table 12 then the power supplied to and the signals returning from the flow element are correct. The problem is most likely a corrupted calibration parameter. Continue troubleshooting at the next section. If the measured values do not correspond to Table 12 and the flow element was proven to function correctly (see previous section), then the flow transmitter is defective. If the previous section checks were not possible and the above values did not correspond, then the problem could be in the flow element or the flow transmitter. Contact Customer Service for details on how to obtain replacements.
Verify the Calibration Parameters
The flowmeter uses a set of predetermined calibration parameters. Most of these parameters cannot change. A “Delta R Data Sheet" is located in the data package. It contains the calibration parameters set in the flow transmitter at the factory. (See the Appendix for a description of these parameters.) Verify that these parameters have not changed using the steps describe below.
1. Identify the appropriate "Delta R" data sheet by serial number. Determine the current group number the flow transmitter by viewing the "Normal Operation" display window. Make sure the current group number corresponds to the group number on the data sheet.
2. Press Home, 5, 1 to enter the "Verify All" function. Verify all calibration parameters listed in the first two columns on the data sheet. Note any differences in values.
3. Press Home, 5, 8 to enter the "Verify Calibration" function. Verify all calibration parameters listed in the second two columns on the data sheet. Note any differences in values.
If any of the parameters have changed, please contact Customer Service. If the parameters have not changed the problem lies elsewhere. Continue with the next section.

In-Depth Troubleshooting The Installation
In-Depth Troubleshooting The Process
Verify Proper Orientation
The flow element must be oriented as described on the "Instrument Information Sheet" located in the back of this manual. Verify that the flat on the flow element is parallel to the pipe and the flow arrow is pointed in the direction of the flow stream. Improper orientation will cause an indeterminate amount of error in the flow measurement. See Chapter 2 for instructions on proper installation.
Verify Proper Insertion Depth
The flow element's thermowells must be located at the center line of the pipe unless the factory specifies otherwise. Improper insertion depth will cause an indeterminate amount of error in the flow measurement. See Chapter 2 for instructions on proper installation.
Verify Standard versus Actual Process Conditions
The flowmeter can measure the mass flow rate if mass units of flow are selected. The mass flow rate is the mass of the gas flowing through a pipe per time. Other flowmeters, such as an orifice plate or a pitot tube, measure the volumetric flow rate. The volumetric flow rate is the volume of gas per time. If the readings displayed by the GF series flowmeters do not agree with another instrument, some calculations may be necessary before comparing them. To calculate the mass flow rate, the volumetric flow rate, and the pressure and temperature at the point of measurement must be known. Use the following equation to calculate the mass flow rate (standard volumetric flow rate) for the other instrument.

NOTE: The rated outputs of fans, blowers or compressors cannot be accurately compared to the flow rate output of the GF series flowmeter.
Swirling Flow and the Length of the Meter Section
The GF series flowmeter is calibrated in a non-rotating flow stream with the streamline parallel to the pipe walls. Rotation of the flow stream or a flow stream that is not parallel to the pipe walls may cause flow measurement errors. A straight pipe run of 20 pipe diameters upstream and 10 pipe diameters downstream generally produces a desirable flow stream. Elbows, valves, and other obstructions, located close to the GF Series Flowmeter may cause an indeterminate error in the flow rate measurement. If a shorter pipe run distance is needed, a flow conditioner can be installed with the flow element. Contact an FCI representative for more information.

If a component of the process media is near its saturation temperature it is probably condensing on the flow element. Liquid on the flow element will drive the flow measurement higher than actual. The flow element must be placed somewhere else in the process where the flow stream temperature is well above the saturation temperature and below the saturation pressure of any of the process gases.
Pulsing or transient flows will cause the flowmeter measurement to be higher than actual. Compressors, fans, blowers, etc. commonly induce pulsation within the flow stream. The flow element should be located at least 20 diameters downstream and 10 diameters upstream of any compressor, fan or blower.
Transient flow (quick increases or decrease flow rate) may cause an indeterminate amount of error in the flow measurement. The flow rate measurements made during quick changes in flow rate should be discarded.
Natural Convection in Vertical Pipes and Ducts
A long, vertical stand of pipe that has no induced flow may have a circulation of gas caused by free convection. If the flowmeter was calibrated to measure small flow rates the convection current may cause a flow reading. If this is undesirable, move the flow element to another location.
Other Troubleshooting
Verifying Delta R’s
The Relays
See Chapter 3 for instructions on setting the relays. From the keypad, the relay state can be switched. This can be used to test the interface with the GF series relays.
To test the relays:
1. From the Main menu press 2. The "2.0 PORT SETUP" menu title will appear.
2. Press 2, the "Relay Setup" option.
3. Press 3, for the "Test Relays" option.
4. Pressing 1 or 2 will toggle the states of the respective relays. The present state of the relays are displayed in parenthesis.
The relays toggle between energized and de-energized and the state should be reported in the status line of the "Normal Operation" window. Changing states also cause an audible click.
NOTE: Be sure to use the ∆R table supplied with this flowmeter. Use two decade
resistance boxes, and or fixed resistors.
A ∆R table is supplied with each flowmeter. The table can be used to verify correct operation of the transmitter independent of the flow element by simulating the RTDs' input with precision resistance decade boxes. In order to verify that the flow transmitter is functioning properly, the inputs from the RTDs may be disconnected and precision resistance of known value substituted. Then measure the flow transmitter output (voltage, current, or relay logic switch points) and compare to the Delta R table. Perform the following steps to verify operation.
1. Verify that the serial number of the flowmeter and the serial number of the Delta R Data Sheet are the same before proceeding. If the serial numbers do not match, the Delta R Data Sheet is not applicable. Each flowmeter has a unique Delta R Data Sheet.
2. Verify the Delta R Data Sheet has the appropriate group number.
3. Disconnect JP3 and connect the decade boxes as shown in Figure 27.
Doc. No. 06EN003352 Rev. B 45 Model GF03 Flow Meter
FLUID COMPONENTS INTERNATIONAL LLC http://www.fluidcomponents.com
Figure 27 - Decade Box Connections
4. Set the reference decade box to 1000 ohms, depending on type of nominal flow element resistance.
5. Set the active decade to the same reading as step 3, plus the ∆ R value from the ∆ R table (i.e. 1000 ohms + 25 ohms = 1025 ohms).
6. For current loop outputs, connect the milliamp meter between the +I OUT (positive lead) and OUT COM (negative lead) on connector terminal JP6 and select a range appropriate for your output current. For the voltage output signals, connect a DMM across the +E OUT and OUT COM on connector terminal JP6.
7. Turn power ON and allow the instrument 10 minutes to stabilize.
8. Be sure the flow transmitter is in the correct group.
9. Increase the decade resistance connected to the active terminal by the value shown in the ∆ R column for the low-limit signal. Set the active decade for a resistance of 1000 ohm + the ∆ R value. The meter reading should equal the recorded value within ±1% of the full signal range.
Example: 4-20 milliampere Output Signal = 1% of 16 milliampere = 0.16 milliampere =
Tolerance.
10. Repeat step 7 for the other flow rates in the Delta R Table for this flowmeter.
11. Compare results of the verification measurements with the output signal values recorded on the Delta R Data Sheet to determine if the transmitter is functioning properly. Also verify the display reading matches.
12. Turn power OFF and disconnect the decade resistors. Connect the proper wires from the flow element to terminal block.
13. Disconnect the milliamp meter. Connect the output load to the appropriate OUT+ and OUT COM terminals on the lower (I/O/P) board.
14. Close the enclosure, making sure that none of the wires are caught. Ensure that all seals and gaskets are properly installed. If a custom enclosure exists, be sure it is placed back into safe operating condition.
If the readings are good, the flow transmitter is good and problem may involve the flow element. If readings are off, a flow element calibration may be required or the flow transmitter needs to be setup.
