WARRANTY
A One Year Warranty comes with each unit against manufacturer’s defects. This does not include clogging due
to lack of regular maintenance or excessive sediment and/or contaminants in water. This warranty also excludes
damage to units caused by using the unit outside of the specified parameters.
Do not operate this flow
meter if incoming pressure exceeds 80 psi.
Should inlet pressure exceed 80 psi, the optional HydroLogic pressure regulator (
HL 10077
) is required for
operation.
IMPORTANT NOTICE
• Use this meter for water only. Do not use to meter fuel or chemicals.
• This meter is not legal for trade applications.
• The meter is very sensitive to electrical “noise” and may not operate correctly if located near some
electrical equipment.
CAUTION:
Blowing compressed air through the turbine assembly could damage the rotor.
Do not contact your dealer or distributor for warranty issues.

If the meter display becomes dim or blank, replace
the batteries as follows:
1. Remove the four Phillips-head screws from the
face of the meter and lift the faceplate from the
turbine.
2. Remove the old batteries and clean any
corrosion from the terminals.
3. Install new batteries. Make sure the positive post
is in the correct position.
4. When the batteries are replaced, the faceplate
will power ON. Check the display to ensure
normal functions have resumed before
assembling again.
5. Re-seat batteries, if necessary, and position
the faceplate on the turbine housing. To avoid
moisture damage, make sure the O-ring is fully
seated. Tighten the four screws on the faceplate.
