PART 1 - INTRODUCTION

General

Application Versatility

The TFXP ultrasonic flow meter is designed to measure the fluid velocity of liquid within closed conduit (pipe). The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and ease of installation.

TFXP transit time flow meters utilize two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers can be mounted in V-mode where the sound transverses the pipe two times, W-mode where the sound transverses the pipe four times, or in Zmode where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. This selection is based on pipe and liquid characteristics. The flowmeter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the time interval that it takes for sound to travel between the two transducers. The difference in the time interval measured is directly related to the velocity of the liquid in the pipe.

The TFXP flow meter can be successfully applied on a wide range of metering applications. The simple to program transmitter allows the standard product to be used on pipe sizes ranging from 1 - 100 inch [ 25 - 2540 mm ] internal diameters. A variety of liquid applications can be accommodated: ultrapure liquids, potable water, chemicals, raw sewage, reclaimed water, cooling water, river water, plant effluent, etc. Because the transducers are non-contacting and have no moving parts, the flow meter is not affected by system pressure, fouling or wear. Standard transducers are rated to 300°F [150°C]. Higher temperatures can be accommodated. Please consult the Dynasonics factory for assistance.

Transmitter Location Considerations

After unpacking, it is recommended to save the shipping carton and packing materials in case the instrument is stored or re-shipped. Inspect the equipment and carton for damage. If there is evidence of shipping damage, notify the carrier immediately.

When the TFXP is to be utilized for extend ed periods of time in one location, the enclosure should be placed in an area that is convenient for servicing, calibration or for observation of the LCD readout.

1. Locate the transmitter within the length of transducer cable that was supplied with the TFXP system. If this is not possible, do not attempt to add additional cable to the transducer. Contact the Dynasonics factory to coordinate an exchange for the proper cable length. Transducer cables that are up to 990 feet [300 meters] are available.

2. Place the TFXP transmitter in a location that is:

♦ Where little vibration exists. ♦ Protected from falling corrosive fluids. ♦ Within ambient temperature limits -40 to 185°F [-40 to

85°C]

♦ Out of direct sunlight. Direct sunlight may increase

temperatures within the transmitter to above maximum limit.

3. If the transmitter will be subjected to a wet environment, it is recommended that the cover remain closed and the latches secured after configuration is completed. The faceplate/keypad of the TFXP is watertight, but avoid letting water collect on the keypad area.

Electrical Connections

Figure 1.4

Battery Charging and External Power Sources

It is highly recommended that the internal battery in the TFXP be fully charged before using the meter for the first time. Details covering this procedure are located on Page 1.1 of this manual.

1. The connectors located on the side of the TFXP consist of three 1/4 turn BNC-type and one 5.5mm power plug. These connectors are environmentally sealed, but it is recommended not to allow water or other liquids to collect in the electrical connections pocket.

2. Connect the appropriate wires to the corresponding connections on the transmitter. The transducer cable has markings of UPSTREAM and DOWNSTREAM to assist in the installation process. The UPSTREAM transducer is the one located closer to the direction from which fluid flow normally comes from (The fluid normally passes the UPSTREAM transducer before passing the DOWNSTREAM transducer.) If the transducer wires are connected backwards, a negative flow indication will be observed on the flow meter display. See Figure 1.4 or the Wiring Diagram located on the inner door of the transmitter.

NOTE: The transducer cables carry low level signals. Do not attempt to add additional cable to the factory supplied transducer cable. If additional cable is required, contact the Dynasonics factory to arrange for an exchange transducer with the appropriate length of cable. Cables to 990 feet [ 300 meters ] are available.

The 12 Volt DC power converter and 12 Volt cigarettestyle power cord connect to the socket connection located on the side of the enclosure. See Figure 1.4. A fully charged battery will provide up to 24 hours of continuous operation before recharging will be necessary. When the battery level has decreased to a point where recharging is required, the LOW BATTERY indicator will illuminate on the front panel. At that point, the meter will only operate a short time more until it automatically turns itself off— preventing excessive battery discharge that can damage

Rev. 4/01 -1.10- TFXP

PART 1 - TFXP TRANSMITTER CONNECTIONS

the Gel Cell battery. If the TFXP is to be used for extended periods of opera-

tion, the 12 Vdc line power converter or the 12 V cigarette converter can remain connected indefinitely.

To charge the internal Gel Cell bat tery, apply power, utilizing the enclosed 12 Vdc line power converter or cigarettestyle power cord, to the TFXP for a period of 16-24 hours. The TFXP has an integral charging circuit that prevents overcharging. The instrument can be permanently connected to AC line power without damaging the flow meter or the battery.

The Gel Cell battery is “maintenance free”, but it still requires a certain amount of attention to prolong its useful life. To obtain the greatest capacity and longevity from the battery, the following practices are recommended:

• Do not allow the battery to completely discharge. (Discharging the battery to the point where the LOW BATTERY indicator illuminates will not damage the battery. Allowing the battery to remain discharged for long periods of time can degrade the storage capacity of the battery.) When not in use, continually charge the battery by keeping the 12 Vdc line power converter plugged in and connected to the flow meter. The TFXP battery management circuitry will not allow the battery to be come “over-charged”.

NOTE: The TFXP will automatically enter a low power consumption mode approximately 1-1/2 minutes after the LOW BATTERY indicator illuminates. This circuit prevents excessive discharge of the internal battery.

• If the TFXP is stored for prolonged periods of time, monthly charging is recommended.

• If the TFXP is stored for prolonged periods of time, store at a temperature below 70ºF [21ºC].

Use wiring practices that conform to local codes (National Electric Code Handbook in the USA). Use only the power converters that have been supplied with the TFXP flow meter. The ground terminal, if present on the converter, is mandatory for safe operation.

Rev. 4/01 -1.11- TFXP

PART 1 - TFXP TRANSMITTER CONNECTIONS

CAUTION: Any other wiring method may be unsafe or cause improper operation of the instrument.

It is recommended not to run line power with other signal wires within the same wiring tray or conduit.

NOTE: This instrument requires clean electrical line power. Do not operate this unit on circuits with noisy components (i.e. Fluorescent lights, relays, compressors, variable frequency drives, etc.).

The TFXP can be operated from a 11-15 Vdc source, using the included cigarette-style power cord, as long as it is capable of supplying at least 3 Watts—observe proper polarity.

PART 1 - TFXP TRANSMITTER CONNECTIONS

General Information Regarding Input/ Output: ISO-MODs

Standard

4-20 mA Output

The TFXP flow meter contains two Isolated Input/output Modules (ISO-MODs); one located inside of the flow meter

enclosure and one that is user accessible, located under the access door on the keyboard. The standard configuration of these modules is to have the internal module configured as an actively powered 4-20 mA module and the user accessible one as a Data Logger.

ISO-MODs are epoxy encapsulated electronic input/output modules that are simple to install and replace in the field. All modules are 2,500 volt optically isolated from TFXP power and Earth grounds -- eliminating the potential for ground loops and reducing the chance of severe damage in the event of an electrical surge.

Seven ISO-MOD options are available including: 4-20 mA, dual-relay, rate pulse, RS232C, RS485, 200k event datalogger and RTD heat-delivered option. TFXP supports any two ISO-MOD input/output modules. All modules are field configurable by utilizing the keyboard or ULTRALINK interface. Field wiring connections to ISO-MODs are quick and easy using pluggable terminals. Features of the various ISO-MODs are described below. See the Series TFXH addendum for details re garding the RTD Heatflow Module option.

The 4-20 mA Output Module interfaces with virtually all recording and logging systems by transmitting an analog current signal that is proportional to system flow rate. Independent 4 mA and 20 mA span settings are established in software using the FL 4MA and FL 20MA settings in the OUTPUT2 conf iguration menu. The se entries can be set anywhere in the –40 to +40 fps [-12 to +12 mps] measuring range of the instrument. Output resolution of the module is 12-bits (4,096 discrete points). The module can drive more than 800 ohms of load with its internally generated 24 volt power source.

A 4-20 mA output interface cable has been included with the TFXP package. Connect the 1/4-turn BNC connection to the jack located on the side of the flow meter. See Fig-

Figure 1.5

leg of the output and the black clip provides the negative side. Verify that the sum of the resistances in the loop do not exceed 800 Ohms.

Refer to Section 3 of this manual for detailed information regarding the configuration, calibration and testing of the 4-20 mA output.

Standard

Data Logger

Figure 1.6

A 200,000-event data logger/electronic stripchart recorder is located within the weather-tight pocket on the face plate of the flow meter. See Figure 1.6. Loosen the three thumbscrews located in the corners of the pocket cover and rotate the cover to expose the Data Logger module. The logger stores time-stamped, high resolution (16-bit) data at user selected intervals ranging from 1 to 30,000 (8.33 hours) seconds. Configuration of and data retrieval from the logger can be accomplished in one of two ways:

• The module is hot-swappable -- that is, it can be in-

stalled, removed from or replaced within the flow meter without disconnecting power. The module can be carried in a shirt pocket back to the office and plugged into a PC serial port via the module's integral DB9 connector.

• Via the DataLink software utility and the serial DB9 in-

terface cable included with the logger. Data can be accessed by connecting the cable to the logger, which is located in the pocket on the front faceplate of the instrument. See Figure 1.6.

Refer to Section 3 of this manual for detailed information regarding the configuration and operation of the Data Logger Module.

Optional

Control Relay

Rev. 4/01 -1.14- TFXP

Two independent SPDT (single-pole, double-throw, Form C) relays are contained in this module. The relay operations are user configured via software to act in either a

PART 1 - ISO-MOD

flow rate alarm, signal strength alarm or totalizer/batching mode. The relays are rated for 200 Vac max. and have a current rating of 0.5 A resistive load [175 Vdc @ 0.25 A resistive]. It is highly recommended that a slave relay be utilized whenever the Control Relay ISO-MOD is used to control inductive loads such as solenoids and motors.

Optional

0-10 kHz Output

Optional

RS232C I/O

The Rate Pulse Output Module is utilized to transmit information to external counters and PID systems via a frequency output that is proportional to system flow rate. This module does not source voltage at its output, it must be connected in an “open-collector” fashion with an external power source and pull-up resistor. Independent Zero and Span settings are established in software using the Flow Measuring Range entries. These entries can be set anywhere in the –40 to +40 fps [-12 to +12 mps] measuring range of the instrument. Output resolution of the module is 12-bits (4,096 discrete points) and the maximum output frequency setting is 10,000 Hz. The MOSFET can support loads of 100V @ 9A.

The RS232 Module can be interfaced with the serial communication ports of PCs, PLCs and SCADA systems that are used to monitor flow rate information in piping systems. The RS232 Module may also be used to form a hardwire connection to a PC that is running the UltraLink software utility. Baud rates up to 19.2k are supported.

Optional

RS485 I/O

Optional

RTD-BTU

Rev. 4/01 -1.15- TFXP

The RS485 Module allows up to 126 TFXP systems to be placed on a single three-wire cable bus. All meters are assigned a unique one byte serial number that allows all of the meters on the cable network to be independently accessed. Baud rates up to 19.2k and cable lengths to 1,000 feet [300 meters] are supported .

See the Appendix of this manual for information regarding connection and operation of the optional RTD-BTU option.

PART 2 - TRANSDUCER POSITIONING

General

The transducers that are u tilized by the Series TFXP contain piezoelectric crystals for transmitting and receiving ultrasound signals through walls of liquid piping systems. The transducers are relatively simple and straight-forward to install, but spacing and alignment of the transducers is critical to the system's accuracy and performance. Extra care should be taken to ensure that these instructions are carefully executed.

Mounting of the clamp-on ultrasonic transit time transducers is comprised of three steps. In general, these steps consist of:

1. Selection of the optimum location on a piping system.

2. Entering the pipe and liquid parameters into either the optional software utility (UltraLink) or keying in the parameters into the TFXP keypad. The software embedded in UltraLink and TFXP will calculate proper transducer spacing based on these entries.

3. Pipe preparation and transducer mounting.

1. Mounting Location

1. Mounting Location1. Mounting Location

The first step in the installation process is the selection of an optimum location for the flow measurement to be made. For this to be done effectively, a basic knowledge of the piping system and its plumbing are required.

An optimum location would be defined as a piping system that is completely full of liquid when measurements are being taken and has lengths of straight pipe such as those described in Table 2.1. The optimum straight pipe diameter recommendations apply to pipes in both horizontal and vertical orientation.

2. Transducer Spacing

2. Transducer Spacing2. Transducer Spacing

TFXP transit time flowmeters utilize two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers can be mounted in Vmode where the sound transverses the pipe two times, W-mode where the sound transverses the pipe four times, or in Z-mode where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. See Figures 2.1-2.3. This selection is based on pipe and liquid characteristics. The flowmeter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the time interval that it takes for sound to travel between the two transducers.

IMPORTANT: Since the time interval being measured is influenced by the transducer spacing, it is critical that the transducer spacing be measured on the pipe accurately to assure optimum performance from the TFXP system.

The TFXP system calculates proper transducer spacing by utilizing piping and liquid information entered by the user. This information can be entered via the keypad or the UltraLink Windows software utility and a laptop computer.

The following information will be required before programming the instrument:

1. Transducer mounting configuration. Use the following guide to determine the optimum mounting method for a particular installati o n:

3. Transducer Mounting

3. Transducer Mounting3. Transducer Mounting

After selecting an optimal mounting location, Step 1, and successfully determining the proper transducer spacing, Step 2, the transducers can now be mounted onto the pipe.

The DTT transducers need to be properly oriented on the pipe to provide optimum reliability and performance. On horizontal pipes, the transducers should be mounted 180 radial degrees from one another and at least 45 degrees from the top-deadcenter and bottom-dead-center of the pipe. See Figure 2.5. Figure 2.5 does not apply to vertically oriented pipes.

Before the transducers are bonded to the pipe surface, two areas slightly larger than the flat surface of the transducer heads must be cleaned of all rust, scale and moisture. Finish the surface with some emery paper, and wipe the surface with a degreasing solvent such as trichlorethylene. Paint and other coatings, if

not flaked or bubbled, need not be removed. Plastic pipes typically do not require surface preparation other than soap and water cleaning.

Figure 2.5 Transducer mounting locations on

horizontal pipe.

Installations on Pipes Smaller than 10 Inches [250 mm] Go to Page 2.18

Mounting Transducers in Z-Mount Configuration

Installation on larger pipes requires careful measurements to the linear and radial placement of the DTT transducers. Failure to properly orient and place the transducers on the pipe may lead to weak signal strength and/or inaccurate readings. The section below details a method for properly locating the transducers on larger pipes. This method requires a roll of paper such as freezer paper or wrapping paper, masking tape and a marking device.

Wrap the paper around the pipe in the manner shown in Figure 2.6. Align the paper ends to within 0.25 inches [6mm].

Mark the intersection of the two pieces of paper to indicate the circumference. Remove the template and spread it out on a flat surface. Fold the template in half, bisecting the circumference. See Figure 2.7.

Rev. 4/01 - 2.16 - TFXP

PART 2 - TRANSDUCER POSITIONING

Figure 2.6 Paper Template Alignment

Crease the paper at the fold line. Mark the crease. Place a mark on the pipe where one of the transducers will be located. See Figure 2.5 for acceptable radial orientations. Wrap the template back around the pipe, placing the beginning of the paper and corner in the location of the mark. Move to the other side of the pipe and mark the ends of the crease. Measure from the end of the crease (directly

PART 2 - TRANSDUCER POSITIONING

across the pipe from the first transducer location) the dimension derived in Step 2, Transducer Spacing. Mark this location on the pipe.

The two marks on the pipe are now properly aligned and measured.

If access to the bottom of the pipe prohibits the wrapping of the paper around the circumference, cut a piece of paper to these dimensions and lay it over the top of the pipe.

Length = Pipe O.D. x 1.57 Width = Spacing determined on 2.12 or 2.14

Mark opposite corners of the paper on the pipe. Apply transducers to these two marks.

PART 3 - STARTUP AND CONFIGURATION

Before Starting the Instrument

Instrument Startup

Note: The TFXP flow meter system requires a full pipe of liquid before a successful startup can be completed. Do not attempt to make adjustments or

change configurations until a full pipe is verified. Note: If Dow 732 RTV was utilized to couple the

transducers to the pipe, the adhesive must fully cure before power is applied to the instrument. Dow 732 requires 24 hours to cure satisfactorily. If Dow 111 silicone grease was utilized as a couplant, the curing time is not required.

Procedure:

1. Verify that all wiring is properly connected and routed as described previously in this manual.

2. Verify that the transducers are properly mounted as described in Part 2 of this manual.

3. Press the ON button on the flow meter keypad. The TFXP display backlighting will illuminate and the software version number and Dynasonics’ logo will appear on the display.

The display backlighting illuminates for approximately 20 seconds and automatically extinguishes to preserve battery power. To re illuminate the display, press any key on the keyboard. Adjustments to the backlighting duration can be made in the Display Menu. Refer to page 3.27 for details.

4. Confirm that Signal Strength is greater than 2%. If it is not, verify that proper transducer mounting methods and liquid/pipe characteristics have been entered.

The pipe must be full of liquid in order to make this measurement.

5. Once the meter is properly operating (proper signal strength has been achieved), refer to the later portions of this manual section for additional programming featur es.

The standard configuration for the TFXP includes a powerful 200,000-event data logger/electronic stripchart recorde r. The logge r ca n be co nf igu red in a co uple of different ways to match user applications. The logger stores time-stamped, high resolution (16-bit) data at user selected intervals ranging from 1 to 30,000 (8.33 hours) seconds. Configuration of and data retrieva l from the logger can be accomplished i n one of two ways:

Figure 3.3

Data Logger Configuration

• The module is hot-swappable -- that is, it can be

installed, removed from or replaced within the flow meter without disconnecting power. The module can be carried in a shirt pocket back to the office and plugged into a PC serial port via the module's integral DB9 connector. This feature eliminates the requirement to carry a laptop computer to the flowmeter site.

• Via the DataLink software utility and the serial DB9

interface cable included with the logger. Data can be accessed by connecting the cable to the logger, which is located in the pocket on the front faceplate of the instrument. See Figure 3.3

See Section 4 of this manual for details regarding operation of the DataLink and UltraLink software utilities.

There are three configuration parameters to enter for datalogger operation:

The TFXP and the datalogger module can be used to monitor and store data on up to 16 different locations. These locations are identified by the FILE NUMBER/ LOCATION that is assigned. The datalogger will not write over an existing file. Existing data files will need to be uploaded and then erased from the logger before new data can be written into the space. Uploading and storing of datalogger files is completed using the DataLink software utility. See Section 4 of this manual for details regarding operation of the DataLink and UltraLink software utilities.

From the OUTPUT 1 menu, adjust the time INTERVAL between readings. INTERVAL values between 1 and 30,000 seconds are acceptable.

CAL 20MA 4-20 TST

The 4-20 mA Output Module interfaces with virtually all recording and logging systems by transmitting an analog current signal that is proportional to system flow rate. Independent 4 mA and 20 mA span settings are established in software using the Flow Measuring Range entries. These entries can be set anywhere in the –40 to +40 FPS [-12 to +12 MPS] measuring range of the instrument. Output resolution of the module is 12-bits (4096 discrete points) and the module can drive up to 800 ohms of load with its internal 24V isolated power source.

The FL 4MA and FL 20MA entries are used to set the span of the 4-20 mA analog output. These entries are volumetric rate units that are equal to the volumetric units configured as Engineering Rate Units and Engineering Units Time Interval entered on page 3.10. These entries may be entered anywhere in the flow measurement range of the instrument (velocity range of –40 to +40 FPS [-12 to +12 MPS]).

For example, to span the 4-20mA output from –100 GPM to +100 GPM, with 12mA being 0 GPM, set the FL 4MA and FL 20MA inputs as follows:

FL 4MA = -100.0 FL 20MA = 100.0

For example, to span the 4-20mA output from 0 GPM to +100 GPM, with 12mA being 50 GPM, set the FL 4MA and FL 20MA inputs as follows:

4-20mA Calibration

FL 4MA = 0.0 FL 20MA = 100.0

The 4-20mA ISO-MOD is factory calibrated and should not require adjustment unless it is replaced.

The CAL4MA entry allows fine adjustments to be made to the “zero” of the 4-20mA output. To adjust the 4mA output, an ammeter or reliable reference connection to the 4-20mA output mus t be pres ent.

NOTE: The CAL 4MA and CAL 20MA entries should not be used in a attempt to set the 4-20mA range. Utilize FL 4MA and FL 20MA, detailed above, for this purpose.

Procedure:

1. Disconnect one side of the current loop and connect the ammeter in series (disconnect either

wire at the terminals labeled +/- on the ISO-MOD 420mA module).

2. Using the arrow keys, increase the numerical value to increase the current in the loop to 4mA. Decrease the value to decrease the current in the loop to 4mA. Typical values range between 40-80 counts.

Re connect the 4-20mA output circuitry as required.

Calibration of the 20mA setting is conducted much the same way as the 4mA adjustments.

The Rate Pulse Output Module is utilized to transmit information to external counters and PID systems via a frequency output that is proportional to system flow rate. Independent Zero and Span settings are established in software using the Flow Measuring Range entries. These entries can be set anywhere in the –40 to +40 FPS [-12 to +12 MPS] measuring range of the instrument. Output resolution of the module is 12-bits (4096 discrete points) and the maximum output frequency setting is 10,000 Hz. The 0.21-Ohm FET output is rated to operate at 100 V and 9 A maximum. This module does not source an output voltage and should be treated as an open collector type of output. An external voltage source and limit resistor must be present.

Rate Pulse Span

Two independent SPDT (single-pole, double-throw, Form C) relays are contained in this module. The relay operations are user configured via software to act in either a flow rate alarm, signal strength alarm, error alarm or totalizer/batching mode. The relays are rated for 200 VAC max. and a have current rating of 0.5A resistive load [175 VDC @ 0.25A resistive]. It is highly recommended that a slave relay be utilized whenever the Control Relay ISO-MOD is used to control inductive loads such as solenoids and motors.

When one of th e relays is set to TOTAL IZE mode, an entry of TOT MULT must be programmed to establish the accumulated flow volume that needs to pass before the relay will “pulse”. The relay will pulse every time that volume is accumulated. The pulse has a duration of approximately 50mSec. Enter a value using

When a relay is s et to FLOW mode, two entrie s must be made: ON and OFF. The ON and OFF entries dictate at what volumetric flow rate (using the volumetric units established as Engineering Units RATE and RATE INTERVAL on page 3.10) the relay turns ON and at what flow rate the relay turns OFF - establishing a deadband. For “fail-safe” mode, the ON setting should be set higher than the OFF setting.

When a relay is set to SIG STR mode, the relay will activate when the measured Signal Strength falls below the Signal Strength Cutoff setting. See page 3.22. When a rela y is set to E RROR mo de, t he relay wil l activate when any error occurs in the flow meter that has caused the meter to stop measuring reliably.

SIG STR - Signal Strength

The measurement of Signal Strength assists service personnel with troubleshooting the TFXP system. In general, expect the signal strength readings to be greater than 5% on a full pipe with the transducers properly mounted. Signal strength readings that are less than 5% may indicate a need to chose an alternative mounting method for the transducers or that an improper pipe size has been entered.

Signal Strength readings in excess of 95% may indicate that a mounting method with a longer path length may be required. For example, if mounted on a 3 inch PVC pipe in V-mode causes the measured Signal Strength value to exceed 95%, change the mounting method to W-mode for greater stability in readings.

PART 3 - KEYPAD CONFIGURATION

Signal Strength Cutoff

Substitute Flow Entry

Signal Strength Cutoff SIG C-OF is used to drive the flowmeter and its outputs to a zero flow state should conditions occur that cause low signal strength. A signal strength indication of between 0.5 and 0.8 is considered to be inadequate for measuring flow reliably, so typical settings for SIG C-OF are in the range of 1.0 to 2.0.

Signal Strength indication of 0.5 to 0.8 is considered to be no signal at all. Verify that the pipe if full of liquid, the pipe size and liquid parameters are entered correctly and that the transducers have been mounted accurately.

Substitute Flow or SUB FLOW is a value that the analog outputs will be driven at when an error condition in the flowmeter occurs. Typical settings are either –5% or 105% - a value outside of the normal operating range that can be used to indicate a fault condition to the target device.

Addendum — Heat Flow

Dynasonics Series TFX Heat Flow

General

The TFX flowmeter with the optional heat flow module installed is designed to measure the rate and quantity of heat delivered to a given building, area or heat exchanger. The instrument measures the volumetric flow rate of the heat exchanger liquid (water, water/glycol mixture, brine, etc.), the temperature at the inlet pipe and the temperature at the outlet pipe. Heat delivery is calculated by the following equation:

Rate of heat delivery = Q*(Tin – Tout)*c Where

Q = volumetric flow rate Tin = temperature at the inlet Tout = temperature at the outlet c = specific heat of the liquid

The RTD module installed in the TFX measures the differential temperature of two 1000-ohm three-wire platinum RTDs. The three-wire configuration allows the temperature sensors to be located several hundred feet away from the TFX meter without influencing system accuracy or stability. The TFX transit time flow meter can also tolerate large distances between the flow measurement transducers and the electronic instrument.

The RTDs included with the TFX heat delivered flowmeter have been factory calibrated and are marked with an identification as to which terminal, #1 or #2, the RTD has been calibrated. The RTDs are 1000-ohm platinum and are designed to be mounted on the exterior surface of the pipe. The RTDs are rated for a temperature range of –50 to +130 C.

Installation

1. Follow the instructions outlined in the standard TFX manual for proper installation of the flow measurement transducers. After installation, verify that the Signal Strength is greater than 4-5% and, if possible, perform a Zero flow calibration on the pipe. Please note that all readings require a full pipe of liquid.

2. Select areas on the inlet and outlet pipes where the RTDs will be mounted. Remove or peel back the insulation all the way around the pipe in the installation area. Clean an area slightly larger than the RTD down to bare metal on the pipe.

3. Place a small amount of heat sink compound on the pipe in the RTD installation location. See Figure 1. Press the RTD firmly into the compound. Fasten the RTD to the pipe with the included heater tape.

4. Route the RTD wires to an electrical junction box in close proximity to the installation location. Secure the RTD wires such that they will not be pulled on or abraded inadvertently. Replace the insulation on the pipe.

5. Route a cable from the electrical junction box back to the TFX flowmeter. Connect the RTDs as illustrated in Figure 2. Note that the SNS1 and DRV1 wires originate from the same location on the RTD.

chosen from the FL TYPE list, a default specific heat will be loaded. This default value is displayed as SP HEAT in the BASIC MENU. If the actual specific heat of the liquid is known or if it differs from the default value, press the ENTER key and modify the value. Press the enter key to save the value. See the values listed in Tables 1 and 2 for specific values. Enter a value that is the mean of both pipes.

3. The RATE UNIT can be displayed as three different values; BTUs, CALs or Watts. Select the proper unit from the RATE UNIT list. Select the appropriate RATE INTERVAL from the list (seconds, minutes, hours, days). Be aware that the instrument can only display values as large as 99,999,999.

4. Select an appropriate TOTALIZER UNIT from the list; BTU, CAL, Watt.

5. In the SER MENU three values can be displayed that may aid in troubleshooting the heatflow instrument. In this menu, the temperature being read by RTD1 is indicated as TEMP1 (all values are degrees Celsius) , RTD2 as TEMP2 and the absolute difference as TEMPDIFF.
