Caution: Follow these instructions to
avoid failure.
Danger: Wear eye protection when
installing or removing flowmeter.
1. Misalignment will damage the meter!
Flowmeter must be installed in an
exact vertical plane to ensure accu-
racy. Be certain of proper plumbing
alignments. Misalignment may cause
the o-ring seals to leak. The
meterbody material can be damaged
by UV rays. Do not install in direct
sunlight.
2. Pipe dope and glue will damage
the meter!
Use only PTFE tape on the threaded
adapters. Polysulfone meter body and
fittings cannot tolerate PVC Glue
and/or pipe dope. Even fumes can
cause severe damage. If you are
installing your flowmeter to a glued
pipe configuration, install the flowmeter
after all glued fittings are dried and
lines are purged of all fumes. Never
hold the meter body with pliers or like
tools. Union nuts should be hand tightened only. DO NOT OVER-TIGHTEN!
3. Vibration and heavy loads will damage the meter!
Wall, floor and ceiling mounts and supports must be carefully aligned with the
meter body and sturdy enough to support the plumbing and prevent vibration.
Never allow the flowmeter to support the weight of related piping.
4. Solenoid valves will damage the meter!
Avoid a system that will impose a sudden burst of flow to the meter. Such a
burst will cause the float to impact the float stop with destructive force. Solenoid
valves, or other quick opening valves cannot be used unless meter is protected
against sudden bursts of flow.
5. High pressures and temperatures will damage the meter!
The maximum acceptable temperature and pressure is interdependent. The
maximum acceptable working pressure is dependant on the actual fluid tempera-
ture. The maximum acceptable fluid temperature is dependant on the actual
working pressure. (see Temperature Vs. Pressure chart).
