Saddle Clamp Installation
The Saddle clamp should be mounted on the pump discharge pipe in an area of laminar flow. Select a location with as long a straight run as possible. Avoid mounting
immediately after an elbow, gate or increase in pipe size (Any thing that would cause
turbulence). Allow a straight run of at least 6 pipe diameters after an elbow.
Cut a 1.5” diameter hole in the top side of the waterwa y. Position the saddleclamp
on the pipe with the indexing hole f acing the pump . Tighten the nuts on the “U” bolt
evenly to 30 ft/lbs.
Paddlewheel
Install the paddlewheel adapter (spacer) to the mount using four 7/16” screws.
Lubricate the O-rings on the paddlewheel and insert it into the mount .
Secure the transmitter with the 4 screws provided.
The Class1 Digital Flowmeter measures water velocity in the pipe to calculate the
flow rate. The location of the paddlewheel transmitter is important for proper operation and accurate readings. Mount the transmitter in a location that is accessible for
future maintenance and in an area where laminar (non-turbulent) flow is most likely
to be maintained. Most problems with flowmeter accuracy and performance can be
traced to the location of the transmitter.
The hole size for the paddlewheel transmitter PN102714 mount is 1-1/2”.
Engineering Standard Number
C1-102046-A
Transmitter Location
Elbows/Bends A straight run of pipe to the transmitter of at least six (6) times
the pipe diameter after an elbow or other turbulence producing item is desirable
for a successful installation. Try to locate the transmitter using the longest straight
section of pipe available. Minimal turbulence at the transmitter provides the most
accurate reading.
Valves/Gates If the transmitter is downstream of a valve, the minimum dis tance is
fifteen (15) times the pipe diameter. Whenever possible, mount the transmitter
before a valve.
Horizontal Pipes The transmitter will work in any position, however when mounted
on a horizontal run, it should be mounted in the top half of the pipe to allow debris
to be flushed out of the paddlewheel.

Increase/Decrease in pipe size The transmitter can be placed after an increase in pipe
diameter, never after a decrease.

flexible hose can greatly assist in reducing the number of elbows and amount of
turbulence between the pump and discharge pipe.
Wiring
The Flowminder system comes with a wiring harness that connects the transmitter
to the display.
The OEM must supply power and ground to the digital display. Consideration
should be given to the conditions under which the display will have power.
The display is internally protected against short circuits, overvoltage and reverse
polarity, but standard installation procedures should provide for circuit protection.
Maximum current used by the flowmeter is 1.5 Amps.
A momentary grounding switch can be added when the totalizer function is desired.
This is connected to the display through the 8 pin mini-connector at pin 8.
Electrical
The Flowmeter Display is connected to the OEM harness with a Deutsch 8 pin
mini-connector.
Mating Connector: DTM06-08S
Locking Wedge WM-8S
Mating Terminal: 0462-201-20141 20 gauge socket
Terminal Assignments: 1 N/C (no connection)
Connection to the vehicle is simply a matter of connecting the RED power wire to a
good 12 VDC voltage source and connecting the BLACK ground wire to a good
system ground.

Operation
The flowmeter displays the current flo w rate whenever the displa y has power and
the discharge is open. Range is 0 to 9995 GPM, LPM or IGPM as calibrated.
Totalizer
The display includes a totalizer function that displa ys the total amount of water
that has been flowed since the unit was turned on. This feature is enab led by
grounding terminal number eight (8) of the display connector .
While terminal number 8 is grounded, activating the left switch resets the totalizer
to zero (0).
The totalizer resets to zero whenev er power is remo ved from the displa y.
Multiply the reading on the display b y 100 (add two zeroes) for total flo w .

5. Calibration
Flowmeter Calibration is performed with the discharge stabilized at the desired calibration flow. (Smoothbore nozzle and Pitot gauge)
The calibration mode is entered by the use of a “password”.
There are two magnetic switches located at the low er corners of the display.
These switches are activated with the use of a magnet, switch activation is visually
confirmed by the lighting of the closest decimal point on the display.
Enter the switch sequence below to enter calibration mode.

Hold the magnet on the right switch until the display reads the Gallons per Minute
(GPM), Liters per Minute (LPM) or Imperial Gallons per Minute (IGPM) that you are
flowing. The speed with which the display increments/decrements the calibration flow
display increases as the switch is held. If you pass the flow value, release the switch
and reactivate. The display will “reverse direction” each time the switch is activated
and the speed will start out at the slowest rate. Maintain the calibration flow f or a minimum of 10 seconds to assure an accurate and stable calibration before activating the
left switch. When the flow is stable and the calibration flow r ate is entered into the
display, activate the left s witch to complete calibration.
The display will read “
Calibration is now complete.
6. Operation
The Flowminder will display the current flowrate whenever the display is enabled
and the discharge is open. Range is 0 to 9990 GPM, LPM or IGPM.

The flowmeter Super System is designed using the digital flowmeter and the digital pressure gauge. Each piece uses the standard digital display cutout. The only additional
consideration from the standard flowmeter is for mounting the pressure transducer. This
should generally be mounted after the valve and is a 1/4 NPT fitting. Use only the 1-1/4”
hex to tighten the transducer, not the body of the sensor. Follow the calibration procedure for pressure and flow as appropriate after installation.
