Ceiling Caution: Follow these instructions to
avoid failure.
Danger: Wear eye protection when
installing or removing flowmeter.
1. Flowmeter must be installed in an exact
vertical plane to ensure accuracy.
Be certain of proper plumbing alignments.
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. Wall, floor and ceiling mounts and supports are to be carefully aligned and
sturdy. Wall, floor and ceiling supports are recommended as needed. This is
to maintain pipe alignment and to prevent vibration.
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 dependent on the actual fluid tempera-
ture. The maximum acceptable fluid temperature is dependent on the actual
working pressure. (see Temperature Vs. Pressure chart).
