Installing Flow Sensor Cable
With the flowmeter in place, install the flow sensor cable.
The flow sensor cable has a GREEN sensor body and mates
with the 3-pin connector on the main harness marked with
a GREEN cable tie. Screw sensor all the way into hole of
flow me ter. Tighten 3/8” jam nut to secure sen sor in place.
Uncoil flow sensor cable and carefully route it to meet the
main harness flow connector marked with GREEN tie. Align
connectors and press firmly together until locking tab clicks
into place. Secure cable with ties provided.

and SprayMate II

II Wiring Diagram on page 10.
NOTE: Sensors with GREEN bodies can be used for either
SPEED or FLOW but not for RUN/HOLD.

Manual Pressure Relief Valve
If you have a positive displacement pump or a cen
trif
u-
gal pump capable of generating excessive pressure, you
must in stall a pressure relief valve and adjust it to a safe
max
i
mum pressure. If a positive dis
place
ment pump is
operated without a pressure relief valve, damage may re sult
to pump or other plumbing component.
See Illustration 9.

The f lowmeter must be installed in the main line after any strainers,
return lines, or valves. Securely mount flowmeter in an area away
from intense vibration. A vertical installation with flow entering the
bottom is preferred, especially at rates below 5 gallons per minute.
Other orientations are sufficient providing the flowmeter remains
full of fluid. To avoid erratic flow readings allow a minimum of 6”
of straight tubing at the flowmeter input and output. If installation
constraints don’t allow this keep bends as gentle as possible.
Micro-Trak® flow meters are bidirectional (exception: green plastic
turbine and mag flowmeters are one direction only). Flipping the
flowmeter periodically (black nylon and stainless steel Micro-Trak®
manufactured models) to reverse the flow will greatly extend the life
of the flowmeter by evening out bearing wear.
