Inspection of the Flowmeter and Compatibility
!
Check for damage while unpacking the flowmeter.
!
Remove any instruction sheets and shipping materials that may have been
inserted into the meter body for shipping reasons.
!
Remove the box containing the float. Note the up position of the float before
removing the float from the meter body (tube). The float must be installed in
the same direction when re-assembling the flowmeter.
!
Remove the pipe fitting adapters with o-rings and the union nuts. Note the
proper location of the o-ring in the groove. Be sure the o-ring is properly
seated during installation.
!
Be sure the meter and the materials of construction are suitable for your
application.
!
The maximum temperature and pressure is shown on the following pages.
!
Although the meter may be suitable for use with other fluids, Blue-White
meters are tested with water and air only. If you are not sure that the meter
is compatible with your fluid, consult the factory.
!
The meter can be damaged by UV light. Do not install the meter in direct
sunlight.
!
Blue-White guarantees the meter is suitable with air and water only.

Installation Guideline
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 temperature. The maximum acceptable fluid temperature is dependent on the actual
working pressure. (see Temperature Vs. Pressure chart).
