Getting acquainted with the flow computer wiring:

Back terminal wiring:

The back terminal wiring indicates the overall positions of the terminal plugs and their functions. Though

the back panel’s jumpers are also shown, refer to the next drawing, “Back Panel Jumpers”, for information

on their settings and functions. The Smart Flow Computer receives its power via the two topmost pins on Terminal P1, on the left of the terminal board. Also on Terminal P1 are, from top to bottom, inputs from the two turbines and the RS-485 serial connection. To the right (P4), from top to bottom, are status input 1, density frequency input, and switch output 1 and 2. Terminal P3, at the lower bottom, handles analog inputs and outputs. These are, in order from right to left, analog inputs 1-4 and analog outputs 1 and 2. Terminal P5, top middle, is the RTD terminal block, "100  platinum RTD input".

Back Panel Jumper

In this illustration, a jumper is “ON” when the jumper block is used to connect the jumper’s to wire prongs.

“OFF” means the jumper block is completely removed or attached to only one of the two wire prongs.

Note: R11 and R3 could have a vertical orientation instead of a horizontal

orientation on certain Smart Flow Computer models.

INPUT/OUTPUT: Assigning and Ranging Inputs

Input/Output Assignment

We will now configure your SFC332L Flow Computer’s inputs and outputs. The flow computer allows the user to configure the inputs and outputs. (I.e. Analog #1 is pressure for Meter #1). The flow computer will not use the unassigned inputs.

How to assign a transmitter to an I/O point

1 Click “Configure Device”, configuration menu is prompted 2 On configuration menu, click “Input Assignment” 3 Enter assignments for DP, temperature, pressure, density and spare inputs.

4 Assignment (1-n). Assignments 1-4 are analog inputs attached

to terminal of the back panel. These inputs accept 4-20mA or 1-5

volts input and are suitable for temperature, pressure, density, or spare inputs. An assignment 5 is strictly RTD (temperature) input only for the meter, densitometer or spare. Assignment 7 indicates a density frequency input; it is assigned automatically once you choose live density frequency input in the setup menu at density type Assignment 10 (module 1) is for Rosemount multi-variable module only. DP, pressure, and temperature for the meter can be assigned. When a frequency type primary element is hooked to the flow computer, the Multi Variable pressure and temperature can be used and the DP becomes a spare input that could be assigned for strainer differential.

Date: 8/1/2019

Page 20

Dynamic Flow Computers SFC332L Manual Quick Start — 1-15

Ranging the Transmitter Inputs:

1. Enter the range values: after assigning the inputs scroll down the transducer inputs

assignment menu to scale the 4-20mA. Enter the value at @4mA and @20mA. Enter both values similar to the way the transmitter is ranged. 1-5 volts is equivalent to 4-20mA. Enter the 1 volt value at the 4mA, and 5 volt value at 20mA. When the Multi Variable is used the 420 ma scale has no effect on anything and does not need to be configured for that input. The reason is simply that the flow computer gets the data via digital communication from the transmitter in engineering units, and therefore a scale is not needed. Normal pressure range is 0-3626, temperature –40 to 1200, DP –250 to 250, or -830 to 830 inches of water.

2. Enter the high and low limits: high limits and low limits are simply the alarm points in

which you would like the flow computer to flag as an alarm condition. Enter these values with respect to the upper and lower range conditions. Try to avoid creating alarm log when conditions are normal. For example: If the line condition for the pressure is between 0 to 500 PSIG, then you should program less than zero for low pressure alarm, and 500 or more for high pressure alarm. High limits are also used in the SCALE for the Modbus variables. The high limit is equalent to 32767 or 4095. The low limit is not used for calculating the scale. The scale starts at zero to wherever the high limit value.

3. Set up the fail code: Maintenance and Failure Code values tell the flow computer

to use a default value in the event the transmitter fails. The default value is stored in Maintenance. There are three outcomes: the transmitter value is always used, no matter what (Failure Code = 0); the Maintenance value is always used, no matter what (Failure Code = 1); and the Maintenance value is used only when the transmitter’s value indicates that the transmitter has temporarily failed (Failure Code = 2).

RTD inputs will skip 4-20 mA assignment because RTD is a raw signal of 50 (ohms) to 156. Readings beyond that range require a 4-20 mA signal to the flow computer or using the built in Rosemount Multi Variable transmitter. The Rosemount Multivariable has a range of –40-1200 degrees Fahrenheit. Density coefficients for raw frequency inputs are programmed in this menu. The menu will only show parameters relevant to the live density selected (i.e., Solartron or UGC, etc.).

WIRING:

Wiring to the flow computer is very straightforward and simple. But still it is very important to get familiar with the wiring diagram.

Wiring the Analog Inputs:

Typical wiring for analog inputs 1 and 2 are shown in the drawing. Analog inputs 3 and 4 are to the left of analog 1 and 2. Note that the analog input has only one common return, which is the -Ve signal of power supply powering the transmitters. When wiring 1-5 volts, make sure to calibrate the flow computer for the 1-5 volt signal because the flow computer calibration defaults for the 4-20mA, which is different from the 1-5 volts. JP5 must be cut for 15 volt inputs. The jumpers for analog 1-4 are in order from right to left. It is possible to cut the first two jumpers for analog 1 & 2 in for 1-5 volts signal and have analog in 3 & 4 as 4-20mA signal. Signal line impedance provided by our flow computer is less than 250. Therefore, when using a smart transmitter that requires a minimum of 250 resistance in the loop, an additional resistor at the flow computer end needs to be installed in series with the 4-20mA loop in order to allow the hand held communicator to talk to the transmitter.

NOTE: The 4-20mA or 1-5 volt DOES NOT source power to the transmitters. You can use the DC

power feeding the flow computer to power the 4-20mA loop IF that power supply is FILTERED.

RTD

The flow computer shows wiring to RTD 1 and RTD 2. 100 platinum can be used; a temperature range of -43F to +300F can be measured. RTD 1 is to the right where P5 designation is. In the figure below notice that each side of the RTD requires two wire connections. When using less than 4 wires a jumper must be used to make up for the missing lead. Internal excitation current source generated is approximately 7mA. .

RTD can be wired to multi-variable directly through specially provided cable. This wiring diagram describes wiring directly into the flow computer and not into the multi-variable.

Dynamic Flow Computers SFC332L Manual Quick Start — 1-19

Wiring Analog Output:

Wiring diagram shows typical Analog output wiring. Notice that analog output will regulate 4-20 mA current loop but DOES NOT source the power for it. External power is required.

ASSIGN ING/R ANGING THE 4-20MA AN ALOG OUT PUTS :

Go to the I/O assignment main menu and click Analog Output Assignment. A selection menu is prompted. Select the analog output number, and then enter what the 4-mA output will indicate and the 20 mA. Make sure that the 20 mA assignment value exceeds the upper range limit of what you assigned the Analog output for, otherwise the analog output will not update beyond 20 mA.

Page 25

Dynamic Flow Computers SFC332L Manual Quick Start — 1-20

Turbine Input Wiring

Scroll to Turbine under Wiring and press  ENTER. Two drawings above each other will show typical wiring for turbine meter 1 and turbine meter 2. When dual pickups from the same turbine are connected, use the inputs for turbine 1 for pickup 1 and turbine 2 for the second pickup coil. When connecting sine wave directly from the pickup coil make sure the distance from the pickup coil to the flow computer is very short--less than 50 feet with shielded cable. In the event there is presence of noise, the distance must be shortened. When connecting sine wave signal, the R11 jumper for meter 1 must be installed and R3 jumper for meter 2 must be installed. (JP3 and JP2 must be off when using sine wave). On the other hand, when using square wave, the square wave signal can be sinusoidal but has to be above 5 volts peak to peak with less than 0.4 volts offset in order for the flow computer to read it. R11 and R3 must be off and JP3 on for meter 1; JP2 must be on for meter 2.

Note: When connecting square wave input, the JP3 and JP2 connect the turbine return to the

flow computer power return. Therefore, signal polarity is very important. Reverse polarity could result in some damage or power loss. When sine wave is used the signal polarity is usually of no significance.

The turbine input is immediately under the power input on terminal P1. The third pin down from the top is Turbine/PD "minus", and below it is Turbine plus. The second pulse input for Turbine/PD meter 2 or the second pickup coil is below turbine one input on P1. The fifth pin down from the top is turbine 2 "minus" signal and below it is Turbine/PD 2 plus signal.

Turbine input wiring for passive (dry contact) pulse generators

Some mass flow meters have pulse outputs that do not provide power but instead require external power, they are referred to as passive outputs, dry outputs, open collector, etc. (For example the Krohne UFM 3030 Mass meter).

In these cases the wiring should be as shown on the below diagram. The pull up resistor can be adjusted to limit the current sink by the Mass meter. For Turbine Input 1 JP3 must be ON and R11 OFF and if using Turbine Input 2 then JP2 must be ON and R3 OFF.

Density Input Wiring:

When using a live densitometer input with frequency signal, the signal can be brought into the Smart Flow Computer in its raw form. The Smart Flow Computer accepts a sine wave or square with or without DC offset. Example for density wiring can be seen in the wiring diagram. Three are two drawings, one with barrier and the other without. Barriers are used for area classification. Notice that the RTD wiring is also drawn to show how to hook the density RTD signal.

Note: When wiring the density input polarity is of significance and reverse polarity could

result in some damage or power loss. The density signal is on connector P4, the third and fourth pin down from the top. The third pin down is density plus, the fourth down is density minus. When Density input is 4-20mA it should be connected as a regular 4-20mA signal to the analog input and not the density frequency input.

CALIBRATION Through Window Program

Calibrations are performed under Calibration. Select inputs to be calibrated, and then select full, single, offset calibration method.

Analog Input 4-20mA or 1-5 volt signal

OFF SET CALIBRATION:

For simple offset type calibration simply induce the signal into the analog input and make sure the SFC332L is reading it. After you verify that the SFC332 recognized the analog input, enter the correct mA reading, and then click OK. The offset type calibration is mainly used when a small offset adjustment needs to be changed in the full-scale reading. The offset will apply to the zero and span. Offset is the recommended method for calibrating the temperature input.

FULL CALIBRATION METHOD:

To perform full calibration be prepared to induce zero and span type signal.

1. Induce the low end signal i.e. 4mA in the analog input.

2. Click inputs to be calibrated under calibration menu, click full calibration, enter the first point

- the analog input value i.e. 4mA, and then click OK button.

3. Now be ready to enter the full-scale value. Simply induce the analog signal and then enter the second value i.e. 20mA, and then click OK button

4. Induce live values to verify the calibration.

TO USE DEFAULT CALIBRATION

1. Select Analog Input

2. Select Reset calibration method

3. Now verify the live reading against the flow computer reading

RTD Calibration:

RTD Calibration is a 2-step process. The first step is a onetime procedure to verify transducer linearity and is done at the time the meter is being setup. The second step is the routine calibration sequence.

Step 1 – Linearity Verification

1- Use a Decade box with 0-150 °F settings. 2- Connect RTD cable to this resistive element for verification of linearity. Verify low and high

points. It must be within ½ degree. 3- Connect the actual RTD element and compare with a certified thermometer. 4- If not within ½ degree do a Full Calibration (See Full Calibration below). If problem persists

verify other elements such as RTD Probe, connections, shield, conductivity of connectors,

etc.

The purpose of the above procedure is to verify zero and span and make sure that the two points fall within the expected tolerance.

Step 2 – Routine Calibration

Once Linearity has been verified through Step 1, the routine calibration procedure is reduced to simply connecting the actual RTD and doing an offset point calibration (see offset calibration below).

Calibration after that will be simple verification for the stability of the transmitter. If it drifts abnormally then you need to verify the other parts involved.

Calibration Procedures through Windows™ Software

At the top menu, go to Calibration and Select RTD Input.

RESET TO DEFAULT CALIBRATION

1. Select Reset calibration method

2. Now verify the live reading against the flow computer reading

OFFSET CALIBRATION:

2. Induce a live value and wait for 10 seconds for the reading to stabilize. Then enter the live value. The value entered must be in Ohm only.

3. Now verify the live reading against the flow computer reading

FULL SCALE CALIBRATION:

1. Prepare low range resistive input (i.e., 80 Ohm.) and High range resistive input (i.e., 120. Ohm).

2. Go to the calibration menu and select RTD full calibration method. Induce the low end (80 Ohm.) resistive signal and then wait 10 seconds, enter live value in ohm value, and click OK button.

3. Induce the High range signal (120 Ohm.) and wait 10 seconds, then enter live value in Ohm

and click OK button.

4. Now verify the live reading against the flow computer reading.

TOOLS

Com Settings

PORT - COMMUNICATION PORT NUMBER (1,2,3,4)

Enter the PC port used to communicate with the SFC332L Flow Computer.

Baud Rate

Note: this parameter must be set the same for both the PC and the SFC332L Flow

Computer for communication to occur.

Baud rate is defined as number of bits per second. The available selections are 1200, 2400, 4800, 9600, or

19200.

Parity

Note: this parameter must be set the same for both the PC and the SFC332L Flow

Computer for communication to occur.

RTU - NONE ASCII - EVEN or ODD

Set the parity to match the Modbus Type.

Data Bits

Options available: 5, 6, 7, or 8. Generally used: 8 for RTU mod, 7 for ASCII mode.

Stop Bits

Options available: 1, 1.5,or28. Generally used: 1.

Modbus Type

Note: this parameter must be set the same for both the PC and the SFC332L Flow

Computer for communication to occur.

The Modbus Communication Specification is either Binary RTU or ASCII.

Unit ID Number

The Unit ID Number is used strictly for communication purposes; it can take any value from 1 to 247. Only one master can exist in each loop.

Note: Do not duplicate the Unit ID number in a single communication loop!

This situation will lead to response collisions and inhibit communications to units with duplicate ID numbers.

Time Out

The amount of time in seconds the program will wait for an answer from the flow computer.

Retry Times

Retry times for the program to communicate with the flow computer in case of timeout.

Auto Detect Settings

Click this button and the configuration program will attempt to communicate with a single SFC332L Flow Computer at different baud rates and formats. Failure to communicate can occur because of a wiring problem, wrong PC port selection, communication parameter mismatch between PC and SFC332L Flow Computer (Modbus type, parity, baud rate, etc.) or lack of power to the SFC332L Flow Computer. To use this feature, the user must insure that only one SFC332L Flow Computer is connected to the PC. More than one SFC332L Flow Computer in the loop will cause data collisions and unintelligible responses

Meter Configuration

METER SETTINGS

Company Name

Up to 20 characters. The company name appears in the reports.

Meter Location

Up to 20 characters. This entry appears only in the report and serves no other function.

Day Start Hour (0-23)

Day start hour is used for batch operation. If daily batch is selected, the batch will end at day start hour; all batch totalizers and flow-weighted values are reset.

Disable Alarms

Use Disable Alarms to ignore alarms. When the alarm function is disabled alarms are not logged. Alarms are also not logged if the DP is below the cut-off limit.

Common Parameters

This feature allows the Flow Computer to use the transmitters on meter one to substitute and compensate for meter two.

Atmospheric Pressure

This pressure is local pressure or contracted atmospheric pressure. (I.e. 14.73 PSI).

Select Scale Value

Scale value use high limit parameters. Full-scale value can be selected using 32767 with sign bit or as 4095 analog values. Example: Temperature high limit is set as 150 Degree F. and current temperature reading is 80 Degree F Scale value will read 17475 = 80/150x32767 (if 0 is selected), or 2184=80/150 x 4095 (if 1 is selected)

Meter Bank

Single or two meters run configuration per individual SFC332L Flow Computer. Enter '1', if two meters are connected to the flow computer.

Bi-Directional

This feature allows a status input to give direction for meter one and two, just meter one, meter two, or the flow computer phase angle feature. The phase angle require dual pickups, therefore this feature is only available with single meter setup only. The phase angle feature relies on high precision quadrature decoder that gives quick and precise direction detection. Bi-directional totalizers will totalize accordingly.

Stream Selection

Single stream can be single meter or bank of two meters. Dual streams allow the user to monitor independent products on separate streams simultaneously.

Date: 8/1/2019

Page 50

Dynamic Flow Computers SFC332L Manual Data Entry — 2-5

Station Total

Station total can add meter one and two, subtract meter one from meter two, or just ignore this feature by selecting none. Station Total does not affect, destroy or otherwise alter the data from either meter. When Station Total is other than none, an additional data parameter, Station Total, is generated by the SFC332L Flow Computer and appears in reports and on the live display monitor.

Select Flow Rate Display

The flow rate will be based on daily basis, hourly, or minute.

Flow Rate Average Second

The flow rate is averaged for 1-10 seconds to minimize fluctuating flow rate conditions. This number

averages the current flow rate by adding it to the previous seconds’ flow rate, and then displays an averaged

smoothed number. Only a low-resolution pulse meter requires this function.

Print Intervals in Minutes (0-1440)

When the second port (RS-232) of the SFC332L Flow Computer is configured as printer port, a snapshot report is generated every print interval (i.e., every five minutes, every hour, or every ten hours).

GM/CC Conversion Factor

This factor is used to reference the density to density of water (i.e. .999012) to establish specific gravity.

Run Switching

Run switching is used to switch from tube one to tube two, when flow rate reaches certain limits. The SFC332L Flow Computer has one active output that can be dedicated to this function. The time delay allows for some delay in switching.

Note: if Run Switching is being used, then the meter should be configured for a single stream (see

Set Up under Meter).

Run Switch High Set Point

When this flow rate value is exceeded and after the delay timer expires, the switch output will activate. This output opens normally meter run two. The SFC332L Flow Computer provides open collector type output that requires external power.

Run Switch Low Set Point

When the flow rate drops below this value and stays below it until the delay timer expires, the output switch will be turned off to shut meter two.

Daylight Saving Time (DST)

Enabling Daylight Saving Time (also called “Summer Time”) sets the Flow Computer to automatically

forward its time by one hour at 2:00 AM on a preset day (“Spring Forward”) of the year and roll back on a second date(“Fall Back”).

If left in auto mode, the computer calculates the DST dates based on USA standards, which are, Spring Forward the first Sunday of April and Fall Back the last Sunday of October.

For countries with other DST dates, the user can enter dates manually. For example, European Summer Time starts the last Sunday in March and ends the last Sunday in October.

Effects of DST on Historical Data

Given the sudden time change that DST creates, the historical reports will show an hour with zero flow at 2:00 AM of Spring Forward Day and an hour with double flow at 1:00 AM of Fall Back Day, to achieve consistent 24-Hour a day flow records.

INPUT/OUTPUT ASSIGNMENT

Parameters in this section are in the submenu I/O | Input Assignment | … unless otherwise noted. Throughout this section the label [Parameter] includes all

these parameters unless otherwise noted: DP, Temperature, Pressure, Density, and Densitometer Temperature.

Transducer Input Assignment

The Flow Computer provides 4 analog inputs, 4 status input, 5 switch outputs, one density frequency input, two turbine inputs, two 4 wire RTD inputs, and 2 multi variable inputs. In order for the Smart Flow Computer to read the live input, the input must be properly assigned and properly wired.

Spare Assignment

This is used for display and alarm purpose only. It is not used in the calculation process. To read spare input value, use the diagnostic screen

4mA and 20mA

Enter the 4mA value and the 20mA value for the transducer. Note that these values cannot be edited if [Parameter] Assignment = 0. Therefore to set the parameter Meter#1 Temperature @4mA the Temperature Assignment parameter cannot equal zero. Note that any [Parameter] can potentially have @4mA and @20mA settings (but not one without the other).

Low/High Limit

Enter the low and high limits. When live value exceeds high limit or less than low limit, an alarm log will be generated. Note that this value cannot be edited if [Parameter] Assignment = 0. Therefore to set the

parameter Meter#1 Temperature Low Limit the Temperature Assignment parameter cannot equal zero.

Maintenance Value

The value to be used when the transmitter fails, or while calibrating. For calibration, set fail code to 1 while calibrating. Note that this value cannot be edited if [Parameter] Assignment = 0. Therefore to set the

parameter Meter#1 Temperature Maintenance the Temperature Assignment parameter cannot equal zero. Note that any [Parameter] can potentially have a Maintenance setting.

Fail Code

Fail Code 0: always use the live value even if the transmitter failed. Fail Code 1: always use the maintenance value

Fail Code 2: use maintenance value if transmitter failed. I.e. 4-20mA is >21.75 or <3.25) Note that this value cannot be edited if [Parameter] Assignment = 0. Therefore to set the parameter Meter#1 Temperature Maintenance the Temperature Assignment parameter cannot equal zero. Note that any [Parameter] can potentially have a Maintenance setting.

Use Stack DP

The SFC3332L Flow Computer allows the user to select dual DP transmitters on each meter for better accuracy and a higher range flow. Use in conjunction with the DP Switch High % parameter setting.

DP Switch High %

The SFC332L Flow Computer will begin using the high DP when the low DP reaches the percent limit assigned in this entry. Example: DP low was ranged from 0-25 inches and switch % was set at 95%. When low DP reaches 23.75 in (= 0.95 * 25) the SFC332L Flow Computer will begin using the high DP provided the high DP did not fail. When the high DP cell drops below 23.75, the Flow Computer will start using the Low DP for measurement.

Density Type

If live density is connected to the meter, user must enter the density type. Raw density frequency or a 420mA input can be selected. This density will be used to calculate mass flow and net flow.

Density 4-20mA Type (Density Unit)

Note that this type of input requires the user to choose a subtype, as indicated in the table above.

Use Meter Temperature as Density Temperature

Allows the meter temperature to calculate the effect of temperature on the densitometer. Make sure the meter and densitometer temperature are similar to avoid measurement errors.

Use Meter Pressure as Density Pressure

To allow the meter pressure to calculate the effect of pressure on the densitometer. Make sure the meter and densitometer pressure are similar to avoid measurement errors.

Densitometer Settings - Density Period Low/High Limits

Density Period is the time period in microseconds. The densitometer fails if the density period exceeds the density period low or high limits. If the densitometer fails and density fail code is set to 2, the maintenance value will be used.

TRA NSDUCER AND MULTI.VARIABLE TAG

Up to 8 alphanumeric ID number. The transmitters are referred to according to the TAG ID. All alarms are labeled according to TAG ID.

User can assign an output to each of the Smart Flow Computer’s output switches from this list. The Smart

Flow Computer switch outputs are open collector type, requiring external D.C power. Outputs in the top list,” Pulse Outputs”, require a definition of pulse output per unit volume. Therefore a Pulse Output Width must be defined when one of these switch types are chosen. These outputs are available through switches 1 or 2 only. Outputs in the bottom list,” Contact Type Outputs”, are ON/OFF type outputs. They can be assigned to any of the five switch outputs. (Switches 1 and 2 can be pulse or contact type output; switches 3, 4, 5 are contact-type output only.)

Pulse Output and Pulse Output Width

Pulse Output is used to activate a sampler or external totalizer. The number selected will be pulses per unit volume or per unit mass. If 0.1 pulse is selected, the one pulse will be given every 10-unit volumes has passed through the meter. Pulse Output Width is the duration, in milliseconds, of one complete pulse cycle (where each cycle is the pulse plus a wait period, in a 50/50 ratio). For example: if POW = 500 millisecond, the Flow Computer at most can produce one pulse each second regardless of the pulse per unit volume selected (500 millisecond pulse + 500 millisecond wait). If POW = 10 millisecond the Flow Computer can produce up to 50 pulses per second. The Flow Computer’s maximum pulse output is 125 pulses/second. The Pulse Output in combination with the Pulse Output Width should be set so that this number is not exceeded.

ANALOG OUTPUT ASSIG NMENT

4-20mA selection must be proportional and within the range of the selected parameter. The 4-20mA signal is 12 bits.

Assignments:

Note: Assignments 4, 8, and 12 are not used.

**Note: Remote control output can be controlled through the Modbus communication link.

MODBUS SHIFT

Reassigns Modbus address registers on one Flow Computer to variables for easy polling and convenience. Use Modbus Shift to collect values in scattered Modbus registers into a consecutive order. The Flow Computer will repeat the assigned variables into the selected locations. Note: some Modbus registers are 2 byte/16 bit, and some are 4 byte/32 bit. Register size incompatibility could cause rejection to certain address assignments. Refer to the manual for more details and a listing of the Modbus Address Table Registers. Example: you want to read the current status of switches #1 and #2 (addresses 2617 and 2618) and the Forward and Reverse Daily Gross Total for Meter #1 (addresses 3173 and 3189). Make assignments such as:

3082=2617 (modbus shift – 2 bytes) 3083=2618 (modbus shift – 2 bytes)

3819=3173 (modbus shift – 4 bytes)

PID PARAMETERS PID CONFIGURATION

(PID) Proportional Integral Derivative control – We call this function PID, however the flow computer performs Proportional Integral control. And does not apply the Derivative. The Derivative is not normally used in flow and pressure control operations and complicates the tuning operation

Use Flow Loop

(Valid entries are 0 or 1) Enter 1 if the computer performs flow control. Enter 0 if the flow computer does not perform flow control.

Flow Loop Maximum Flow rate

Enter the maximum flow rate for this meter. This rate will be basis for maximum flow rate to control at.

Flow Set Point

Enter the set point. The set point is the flow rate that the flow computer will try to control at.

Flow Acting – forward or reverse

Enter 0 if the control is direct acting, Enter 1 if the control is reverse acting. Direct acting is when the output of the controller causes the flow rate to follow in the same direction. The output goes up and the flow rate increases. A fail Close valve located in line with the meter will typically be direct acting. If the Controller output signal increases, the control valve will open more causing the flow rate to increase. Reverse acting is when the output of the controller causes the opposite action in the flow rate. A fail open valve in line with the meter will typically be reverse acting. If the Controller output increases the control valve will close some causing the flow rate to decrease. Care must be taken to study where the valves are located in relation to the meter and whether the valves are fail open or fail close to understand if the controller should be direct or reverse acting. Some control valves can be fail in position (especially electrically actuated control valves). This valve should be studied to understand if the actuators themselves are direct or reverse acting.

Use Pressure Loop

(Valid entries are 0 or 1) Enter 1 if the computer performs pressure control. Enter 0 if the flow computer does not perform pressure control.

Pressure Maximum

Enter the Maximum pressure for this meter. This pressure will be basis for Maximum pressure to control at.

Pressure Set Point

Enter the set point. The set point is the pressure that the flow computer will try to control at.

Pressure Acting – forward or reverse

Enter 0 if the control is direct acting, Enter 1 if the control is reverse acting. Direct acting is when the output of the controller causes the pressure to follow in the same direction. The output goes up and the pressure increases. A fail open valve located in the line downstream of the meter will typically be direct acting to maintain the pressure at the meter. An Increase in the output from the controller will cause the control valve to close thus causing the pressure to increase. Reverse acting is when the output of the controller causes the opposite action in the flow rate. A fail close valve in the line downstream of the meter will typically be reverse acting to maintain the pressure at the meter. An increase in the output signal will cause the valve to open, which will cause the pressure to be released thus causing the pressure to decrease. Care must be taken to study where the valves are located in relation to the meter and whether the valves are fail open or fail close to understand if the controller should be direct or reverse acting. Some control valves can be fail in position (especially electrically actuated control valves). These valves should be studied to understand if the actuators themselves are direct or reverse acting.

PID TUNING

Flow Controller Gain

(Allowable Entries 0.0 – 9.99) The gain is effectively 1/Proportional Band. The basis of theory for proportional band is the relationship of the percentage of the output of the controller to the percentage of the change of the process. In this case, if the control output changes 5% the flow rate should change 5%, the proportional band would be 1.0 and the gain would be 1.0. If the percentage of the output is 5% and the flow rate would change by 10%, the proportional band would be 2 and the Gain would be 0.5 However since you do not know until you are flowing the effect of the output on the flow rate, you have to start somewhere. A good starting point is to use a proportional band of 0.5 if the valve is properly sized.

Flow Controller Reset

(Allowable Range 0.0 – 9.99) Reset is the number of minutes per repeat is the time interval controller adjusts the output to the final control element. If the reset is set at 2, the flow computer will adjust the signal to the flow control valve every 2 minutes. If the Reset is set at 0.3, the output signal will be adjusted approximately every 20 seconds, until the process and set point are the same. The rule of thumb is the reset per minute should be set slightly slower that the amount of time it takes for the control valve and the flow rate to react to the flow computer output signal changing. This can only be determined when there is actual flow under normal conditions. It is best to start the reset at

0.3 or reset the signal every 3 minutes, if the control valve is properly sized.

Pressure Controller Gain

(Allowable Entries 0.0 – 9.99) The gain is effectively 1/Proportional Band. The basis of theory for proportional band is the relationship of the percentage of the output of the controller to the percentage of the change of the process. In this case, if the control output changes 5% the pressure should change 5%, the proportional band would be 1.0 and the gain would be 1.0. If the percentage change of the output is 5% and the pressure would change by 10%, the proportional band would be 2 and the Gain would be 0.5. However since you do not know until you are flowing the effect of the output on the pressure, you have to start somewhere. A good starting point is to use a proportional band of 0.5 if the control element is properly sized.

Pressure Controller Reset

(Allowable Range 0.0 – 9.99) Reset is the number of times per minute the controller adjusts the output to the control valve. If the reset is set at 2, the flow computer will adjust the signal to the final control element every 2 minutes. If the Reset is set at 0.3, the output signal will be adjusted approximately every 20 seconds, until the process and the set point are the same. The rule of thumb is the reset per minute should be set slightly slower that the amount of time it takes for the control valve and the pressure to react to the flow computer changing the output. This can only be determined when there is actually flow under normal conditions. It is best to start the reset at 0.3 or reset the signal every 3 minutes, if the control element is properly sized.

HISTORICAL DATA

VIEW, CAPTURE AND STORE

To retrieve historical data, go to Historical Data menu. The View option retrieves the data from the flow computer but does not store the information into the database. The second option, Capture and Store, retrieves the information, shows it on the screen and stores it on the database.

The available types of reports are:

PREVIOUS HOURLY DAT A

Up to 50 previous hour data are stored in the Flow Computer. Enter first report and the Flow Computer will go backward from that selected report. Current hour cannot be selected.

PREVIOUS DA ILY DATA

Up to 50 previous daily reports can be retrieved.

ALA RM REPORT

Up to 100 previous alarm data can be retrieved. The data are starting from the most recent to the oldest.

AUDIT REPORT

The audit trail report shows configuration parameter that has changed which could influence the calculated numbers. The Flow Computer provides up to 100 event logs. One purpose for audit trail is to back track calculation errors that result from mistakes by the operator of the flow computer operator.

BAT CH REPORT

Up to 50 previous batch reports can be retrieved.

Viewing previously captured reports

Once a report is stored in the database using the Historical Data | Capture and Store option it can be seen using the Previously Captured Reports option under the Historical Data Menu.

When the option is selected, a dialog will appear asking for the name of the report you want to

see. There is a “View last captured report” option than will show the data acquired the last time

from a device. If you want to see another report different than the last one just type the name of the report in the space provided. The browse button can be used to see the list of reports stored in the database.

Date: 8/1/2019

Page 82

Dynamic Flow Computers SFC332L Manual Data Entry — 2-37

Exporting or Printing Reports

Once the data is retrieved from the Flow Computer it is shown in a report format, like the picture above. On this window there are several buttons.

 Arrow buttons let you go through all the reports captured.  The Print Button (shown o the picture) lets you print the report to any printer installed in your

computer. The printed version will look just like it is shown on the screen.

 The Export Button allows the user to save the report in different formats. Once the button is

pressed a small dialog appears showing the different formats available (see following picture).

In the first box select the format you want the file to have. Excel, Word or HTML formats are recommended because they preserve the report format. The plain text formats (text-format, CSV comma separated values, tab-separated values) include all the information but will require user modification to improve readability. The other text formats are text or paginated text. IMPORTANT: when a report is exported to text format it can only be 80 character wide, thus, some numbers might appear together making it hard to determine their original values. (i.e. values 1.2543 and 34.2342 on following columns might appear as 1.254334.2342).

Once the export format is selected, press OK and a dialog will appear asking for the file name that you want for the report. Type in the name and press SAVE.

SCHEDULED AUTO POLLING

Automatic Data Polling

Use the Historical Data | Scheduled Auto Polling to retrieve report information from devices in a periodic basis automatically.

These are the following settings:

Enable Automatic Data Retrieval: Check this option to enable the automatic polling. If the

automatic polling function is enabled an “AUTOPOLL” message will appear on the application’s

status bar (bottom-right corner of the application window).

Reports to Retrieve: check the reports you want to get from the devices, you can select as many as you want, just make sure the polling interval is long enough to allow the PC to retrieve the archive. For example, if the computer is programmed to poll 100 reports every 10 seconds, there will not be enough time to get the report before the next poll starts and data will be overlapped.

Report Name: provide a name to the reports captured so they will be available for viewing, printing and exporting.

Starting Day: Type the date where the poll is going to start. Select “Every Day” is the date doesn’t matter.

Polling Time: select the time you want the automatic polling to start, then select “Poll One Time”

if you want to execute these poll only once or select “Poll Every…” and type the polling interval for periodic polls. For example, to poll every hour and a half select “Poll Every…” and type 90 in

the Minutes field. IMPORTANT: Do not use straight hours as starting time (i.e. 7:00, 8:00). The flow computer calculates and updates its information at the beginning of the hour so if data is retrieved at this time it might be erroneous. Allow about 5 minutes for the flow computer to update the data.

Polling List: Add all the units you want to get data from on every poll. You can add up to 100 units. To add

a unit, just click “Add” and then type the unit’s Modbus ID number.

NOTE: The file C:\AutoPoll.log will contain all the logs for the automatic poll, it will tell if there was a

problem or if the data was retrieved successfully.

MODBUS PROTOCOL

TRANSMISSION MODE

ASCII FRAMING

Framing is accomplished by using colon (:) character indicating the beginning of frame and carriage (CR), line feed (LF) for the end of frame

ASCII MESSAGE FORMAT

RTU FRAMING

Frame synchronization is done by time basis only. The Smart Flow Computer allows 3.5 characters time without new characters coming in before proceeding to process the message and resetting the buffer.

FUNCTION CODE

To inform the slave device of what function to perform

ERROR CHECK

LRC MODE

The LRC check is transmitted as two ASCII hexadecimal characters. First, the message has to be stripped of the :, LF, CR, and then converted the HEX ASCII to Binary. Add the Binary bits and then two's complement the result.

CRC MODE

The entire message is considered in the CRC mode. Most significant bit is transmitted first. The message is pre-multiplied by 16. The integer quotient digits are ignored and the 16-bit remainder is appended to the message as the two CRC check bytes. The resulting message including the CRC, when divided by the same polynomial (X16+X15+X2+1) at the receiver which will give zero remainder if no error has occurred.

EXCEPTION RESPONSE

Exception response comes from the slave if it finds errors in communication. The slave responds to the master echoing the slave address, function code (with high bit set), exception code and error check. To indicate that the response is notification of an error, the high order bit of the function code is set to 1.

BROADCAST COMMAND

All units listen to Unit ID Zero, and none will respond when that write function is broadcasted.
