Remove the power from the instrument. Move the jumper on
the left and middle pins to the right hand and middle pins.
Reapply the power momentarily. Turn the power off and
move the jumper back to the left and middle pins. Reapply
the power; the totalizers should read zero (0).
Flow Rate Over—There are a number of discrepancies that
can cause the OLOLOL indication, listed below.
•

•
Instrument is calibrated for a different meter.
Meter flow rate exceeds instrument calibration rate.
Meter maximum flow capacity is exceeded.
To eliminate a flow rate calibration problem check that the
meter and instrument calibration agree. If recalibration is
necessary refer to module #2 in the Instrument Recalibration
Section.
CntA dP – (Numeric selection depends on the factors
determined below.)
CntA ScF – (This factor equals the desired totalizer registration
divided by the number of pulses for that registration. The
number varies with each meter and registration. Example for
a W2000 DRE meter reading in gallons. 500.9663 pulses
equals 1000 gallons. Therefore, the factor is 1/500.9883 or
0.0019961. Only four(4) digits can be entered for the factor.
Therefore, the number entered would be 0.0020, the factor
rounded off. To improve the accuracy the decimal should
be moved two (2) places and the factor becomes 0.19961.
Since the decimal was moved two (2) places, the selection
for CntA dP above is 0.00 and the factor entered into Cnt
ScF is 0.1996.
CntA rSt—to CtLd
Calibrating The Readout
CntA dir—NOr
CAUTION: All instruments are preprogrammed to
operate with the meter specified when ordered and
no additional programming is required. Entering the
program mode may cause erroneous operation. This
should only be done when the operating specifications
have changed.
CntA Ld—000000
To enter the programming mode, depress and hold the SEL
button on the readout for 2 seconds. In the program mode
the display will show Pro and flash to nO. There are five
(5) programming modules available. Press the RST button
to step through the modules. When the correct module is
displayed, press the SEL button to enter that module.
Cntb Bat—nO
Cntb dP – (Usually the same as CntA dP) If the units of
measure are not the same use the procedure listed above
to determine the decimal point location and factor. Possible
examples are one totalizer reading in gallons and the second
in cubic feet, cubic meters or imperial gallons.
Cntb ScF – (Usually the same as CntA ScF, if not use the
procedure listed above.)
RSt P – UP – nO
USEr InP – reset
In the module the function being programmed is shown then
flashes to the value presently entered for the function.
USEr ASn – both A – b
Pressing the RST button stops the display from flashing and
places the unit into the data selection mode.
Module #2 (2 – rAte)
In the selection mode the operator presses the RST button
to scroll through the parameters available for that menu.
RAtE dP – The decimal location depends on the flow rate
value. Typically is set to display the multiplier to use all six
digits on the display. (This setting is determined below.)
When the desired selection is displayed press the SEL
button to store the data and advance to the next menu. When
setting numerical values use the RST button to increment
the flashing digit, and momentarily press the SEL button to
advance to the next digit. To start the least significant digit
flashing momentarily depress the RST button.
To exit the programming mode and save all parameters
step through the module until one of the five main modules
is displayed, then press the SEL button until Pro nO is
displayed. Pressing the SEL button at this point enters the
data and closes the program mode.
THIS PROGRAMMING PROCEDURE ONLY APPLIES 5
TO VERSION 3.0 AND 3.1 READOUTS.
PROGRAM MENUS
Module #1 (1 – input)
InP A-b – dual Cnt
RAtE Enb – yES
RAtE dSP – This number represents the maximum flow
rate to be displayed. In establishing this number, all 6 of the
available digits should be used if possible. (This setting is
determined below.)
RAtE InP – (The Hertz value at the programmed flow rate.
This number should be enhanced as follows: For a W2000
DRE the maximun flow rate is 2500 GPM. At 20.87 hertz.
The 2500 could be used for RAtE dSP above, but to improve
the accuracy it should be set to 25000. The decimal was
moved one place to the right, the hertz value must also be
moved one place to keep proportions the same. Therefore,
RAtE dP should be 0.0, RAte dSP should be 25000.0 and
the hertz set to 208.7.

To activate set point 2. Set the first step SPt SEL to SP2
and the second step SP2 Enb to yES. Follow the above
procedure starting with SPt ASn.
Module #5— (5—SeriAL)
The serial communications are only accessible when an
optional RS232 or RS485 serial communications module
is ordered in the instrument. A separate data sheet and
programming is included with this option.
Setting Option B Factors
The option B factor is coded in binary and can be changed
in the field to any whole number between 1 and 4095. To
determine the factor the following procedure should be used.
1. Determine the quantity that the contact closure
represents.
2. Determine the value of a pulse from the meter in either
quantity per pulse (cubic feet/pulse) or pulses per
quantity (pulses/cubic foot).
3. Determine factor as follows (assuming desired output is
in 1000 cubic feet increments and meter output is 0.564
cubic feet per meter pulse).
a. Calculate the pulses per cubic foot by determining the
reciprocal of 0.564.
1/0.564= 1.7730496 Pulses/Ft3
NOTE: If meter data is available in pulses per cubic foot, this
step can be eliminated.
b. Multiply the pulses per cubic foot by the quantity to be
indicated. (In this example 1000).
1.7730496 X 1000 = 1773.0496 pulses per 1000 ft3.
c. Since the circuitry is only capable of handling whole
numbers, the factor must be rounded to the nearest
whole number (1773).
TH-W-APK-00-00-0612-05-A
Page 5 of 8
NOTE: When the factor is rounded , a small error is
introduced, in this example .0028%. In applications where
this error is not acceptable the addition of option I or using
option Bb will reduce the error considerably.
d. To set the factor on the option B on the option B board
locate the 12 position dip switch on the board. To start,
place all 12 switches in the off position. Setting the factor
is accomplished by turning the dip switch ON so that the
sum of the factors equals the number desired. There is a
unique combination of factors for each desired number.
They are determined in the following manner, select
the largest binary number from the chart that does not
exceed the balance, continue selecting and subtracting
until the balance equals zero (0). At this point, all factors
subtracted must be set into the instrument by placing the
associated switch in the ON position.
3. Apply the formula noted in step #1 to determine the
calculated Range capacitor value. Example: For a
W2000 Turbo Meter at 2500 GPM.
C = 1.54 / 20.874
C = .0738 microfards.
4. A .0738 microfard capacitor is not a standard, that
cannot be procured. To be in the calibration range of
the adjusting pots, the C value selected must be within
10% of the calculated valve. This may require paralling
capacitors to reach the desired value. To achieve
maximum adjusting range, the final value should be a
close to the calculated value as possible.
Example: The calculated value is .0738 microfarads,
therefore, the final capacitor value must be within the 10%
range of .0664 to .0810 microfarads. Although there is a
standard .068 microfarad capacitor available, it is at the
low end of the range. To move the final selection closer
to the middle, the .068 microfarad capacitor should be
paralleled with an .0068 microfarad capacitor increasing
the value to .0748 microfarads. Because you are limited
to available capacitor values and all capacitors have a
tolerance some trail and error may be necessary if a
capacitance meter is not available.
5. Install the correct capacitor values on the PC Board.
The stability of the range capacitor affects stability of the
converter; only polycarbonate or polystrene capacitors
should be used.
The D/A converter is factory set to a precise frequency to
match the water meter or signaling device. If it becomes
necessary to recalibrate the D/A converter, the following
procedure must be followed and high quality test equipment
used. Any component changes must be made with equivalent
components.
Range Capacitor Selection
The range capacitor value is determined by the frequency
output and the desired range for the meter that is driving it.
To determine the Range Capacitor value:
Test Equipment Setup (Using a milliampere meter)
To calibrate the converter you need a signal generator with a
digital readout and a digital VOM that can read milliamperes
in the 20 milliampere range. A voltmeter can be used with a
precision resistor. The signal generator must have a open
collector or a switch output. See option 1. The typical signal
generator has a pulse type output. To use this type of signal
generator a switching type transistor must be connected
between the signal generator and the instrument being
calibrated. See figure #2.
1. Use the formula C range 1.54 / f (C value is in
microfarads.)
2. Determine the full scale frequency value for the signal
source. Exp. A 6” W2000 Turbo Meter outputs 20.874
hertz at 2500 GPM. If the 20 mA signal represents 2500
GPM then use 20.874 hertz for the (f) value in the above
formula. If the 20 mA is to equal a lower flow rate then
scale the frequency value to the lower requirement. For
example assuming a desired maximum flow of 1500
GPM or 60% of the maximum flow range, the frequency
at that flow rate is 60% of the 20.874 hertz or 12.524
hertz.
1. Disconnect the AC power to the instrument.
2. Disconnect any equipment connected to the 4 - 20 mA
output terminals.
3. Connect a milliampere meter directly across the 4-20
mA terminals on the instrument.
TH-W-APK-00-00-0612-05-A
Page 6 of 8
4. Connect the signal generator to the instrument being
calibrated. The plus output of the signal generator is
connected to the Signal Input terminal of the instrument.
Connect the minus or ground terminal of the signal
generator to the Ground terminal of the instrument. The
+12 VDC terminal is not connected. Using a voltmeter
insure that the 12 VDC output is present. (See Figure#2)
5. Apply power to the instrument.
6. Set the signal out of the signal generator to 0 Hertz out.
7. Check the output current by placing a milliampere
meter directly across the 4 - 20 mA output terminals. It
should read 4 milliamperes, if it does not adjust the zero
potentiometer until the meter reads 4.
NOTE: The 4 - 20 mA signal does not respond immediately
when the potentiometer is adjusted. Adjustment should be
in small increments allowing time for the current to stabilize
before further adjusting.
8. Set the signal generator to the full scale hertz value. The
milliampere meter should read 20 milliamperes. If it does
not, adjust the SPAN potentiometer to 20 milliamperes.
Again, adjustment should be in small increments
allowing time for the current to stabilize before further
adjusting.
9. Return to step #6 and readjust the zero setting if
necessary, then again check the full scale value. This
process of checking the zero and full scale values may
have to be repeated 4 or 5 times. The adjustment should
be smaller each time until the final values are achieved.
10. Set the signal generator to half scale (50% of the full
scale hertz). Check the milliampere meter, it should read
12 milliamperes. If it does not check zero and full scale
again. If the 12 milliampere output can not be achieved,
the circuit is not linear and can not be calibrated. It
should be returned for repair.
11. Disconnect the milliampere meter and reconnect the
water meter transmitter. Apply power.
Test Equipment Setup (Using a volt meter)
To calibrate the converter you need a signal generator with
a digital readout and a digital VOM that can read voltage in
the range determined by the resistor selected. The signal
generator must have a open collector or a switch output. The
typical signal generator has a pulse type output. To use this
type of signal generator a switching type transistor must be
connected between the signal generator and the instrument
being calibrated. See figure #1 and #2.
1. Disconnect the AC power to the instrument.
2. Disconnect any equipment connected to the 4 - 20 mA
output terminals.
3. Connect a precision resistor across the 4- 20 mA
terminals on the instrument The resistor value can be
between 1 to 500 ohms. The value selected depends on
the voltage required by the external device being driven,
resistor availability and the range of the voltmeter. For
this procedure we used a 500 ohm resistor . The voltage
out would be 2 (.004 X 500) to 10 (.020 X 500) volts.
4. Connect the signal generator to the instrument being
calibrated. The plus output of the signal generator is
connected to the Signal Input terminal of the instrument.
Connect the minus or ground terminal of the signal
generator to the Ground terminal of the instrument. The
+12 VDC terminal is not connected. Using a voltmeter
insure that the 12 Vdc output is present. (See Figure#2)
5. Apply power to the instrument.
6. Set the signal out of the signal generator to 0 Hertz out.
7. Check the output voltage by placing a volt meter directly
across the resistor. It should read 2 volts, if it does not
adjust the zero potentiometer until the meter reads 2
volts.
NOTE: The voltage does not respond immediately when the
potentiometer is adjusted. Adjustment should be in small
increments allowing time for the current to stabilize before
further adjusting.
8. Set the signal generator to the full scale hertz value.
The volt meter should read 10 volts. If it does not, adjust
the SPAN potentiometer to 10 volts. Again, adjustment
should be in small increments allowing time for the
voltage to stabilize before further adjusting.
9. Return to step #6 and readjust the zero setting if
necessary, then again check the full scale value. This
process of checking the zero and full scale values may
have to be repeated 4 or 5 times. The adjustment should
be smaller each time until the final values are achieved.
10. Set the signal generator to half scale (50% of the full
scale hertz). Check the volt meter, it should read 6 volts.
If it does not check zero and full scale again. If the 6 volt
output can not be achieved, the circuit is not linear and
can not be calibrated. It should be returned for repair.
11. Disconnect the milliampere meter and reconnect the
water meter transmitter. Apply power.

8. Press the SEL button 5 times. Readout should read
SP2-rSt yES, if not set to yES with the RST button.
In all other cases SP2-rSt should be set to nO.
9. Press the SEL button until the readout returns to normal
operation.
* bOUNd causes the relay to close when the flow rate equals
or exceeds set point. If the flow rate falls below the set point
the relay will open.
** LAtCH causes the relay to close when the flow equals
or exceeds the set point. Once closed it will remain closed
regardless of flow rate until the RST button is pushed.
Change Counter A and/or Counter b Scale Factor
1. If the counter scale factor must be changed, this is
accomplished in Module #1.
2. Go to PRO nO If instrument is locked follow the
Unlock procedure above to unlock.
3. Press the RST button once the readout should read
1 - INPUt
4. See procedure for Module #1 in the Program Modules
under CntA Scf. In the example the CntA ScF was 0.1996
with two (2) decimals entered under CntA dP. Following
the same logic 50.09663 pulses equals 100 gallons, the
reciprocal is 0.019961. To change to 100 gallon counts
change CntA dP to 0.0 (one (1) decimal ) and leave CntA
ScF at 0.1996. To change to 10 gallon pulses, change
Cnt dP to 0 (no decimals). After completing, press
SEL until the display shows Pro nO. Pressing it again
will return the display to normal operation. The above
procedure may be used for counter b by changing Cntb
Scf and Cntb dP.

Reducing the value of the counter b allows for smaller
quantities to be detected by option Bb. If the value of
counter b is 1000 gallons the Bb option can only count in
1000 gallon increments. Setting the value to 10 gallons then
any increment of 10 can be programmed. For example a
750 gallon contact closure would not be possible with 1000
gallon increments, but with 10 gallon increments with a set
point of 75 ( SP1 VAL = 75) it can be achieved. Reducing the
value of a count may cause a slight error in the total value.
Programming Option Bb ( Pulse Width and/or Value)
1. Determine the factor to obtain the desired contact
closure output. Example: For a W2000 DRE 500.96639
pulses represent 1000 gallons. To determine the factor,
take the reciprocal of the pulses per 1000 gallons.
(1/500.96639) = .001996)
Totalizer Reset
The electronic totalizer flashes “Cnt OVEr” to indicate that
the totalizer has rolled over. When this occurs, a manual
reset is necessary. With a NEMA4X enclosure, open the
door. Locate the 3 pin connector on the printed circuit board;
it is on the side of the board opposite the transformer above
the mounting hole. There is a 2 place (blue or black) jumper
on the 2 pins on the left side of the connector. Remove the
jumper and place it temporarily on the center and right hand
pins. This must be done with the power on, if preferable, turn
the power to the instrument off before moving the jumper.
After placing the jumper on the center and right pins, turn the
power on; this resets the totalizer to zero (0). After resetting,
move the jumper back to the orginal position.
2. Go to Pro nO. If instrument is locked follow the Unlock
Procedure above to unlock.
3. Press the RST button four (4) times the readout should
read 4 - SEtPt.
4. Press the SEL button once. Readout should read SPt
SEL - SP1. If not read SP! press the RST button until
it does.
5. Press the SEL button 2 times. Readout should read SP1
ASn - count b. If not press the RST button until it does.
6. Press the SEL button the readout should read SP1
Act t-Out. If not press the RST button until it does.
7. Press the SEL button the readout should read SP1 tOUt and change over to a number. This is the pulse
width in seconds if acceptable press SEL if not change
to desired number and press SEL button.
8. Pressing the SEL button above causes the display to
read SP1 VAL and change over to a number. This is the
number of counts on counter b that equal a pulse out.
For example if counter b is reading 10 gallon increments
and SP1 Val reads 100 this will create 1000 gallon
pulses. (10 X 100 = 1000)
9. Press the SEL button until the readout returns to normal
operation.
