Digital Flowmeter Information
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”.

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.
Class1
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.
