Inspection of the Flowmeter and Compatibility

BLUE-WHITE INDUSTRIES LIMITED WARRANTY

FLOWMETERS are warranted to be free of defects in material and workmanship

for up to 12 months from the date of factory shipment. Warranty coverage is
limited to repair or replacement of the defective flowmeter only. Blue-White
Industries does not assume responsibility for any other damage that may occur.

This warranty does not cover damage to the flowmeter that results from misuse
or alterations, nor damage that occurs as a result of: meter misalignment,
improper installation, over tightening, use of non- recommended chemicals, use
of non-reccomended adhesives or pipe dopes, excessive heat or pressure, or
allowing the meter to support the weight of related piping. Flowmeters are tested
and calibrated with water and air only. Although meters may be suitable for other
chemicals, Blue-White cannot guarantee their suitability.

Flowmeters are repaired at the factory only. Call or write the factory to receive a
Return Authorization Number, carefully pack the flowmeter to be returned,
including a brief description of the problem. Note the RA number on the outside
of the carton.

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. (A length of
tubing is sometimes inserted into the meter body to prevent float
movement during shipping).

!

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.

Installation Guideline

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 accu­racy. 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

Floor

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

Pressure Temperature and

Pressure and temperature limits are inversely proportional. At the maximum
suggested pressure the temperature should approach 70°F / 21.1°C; at the
maximum suggested temperature the pressure should approach zero psi. We
cannot guarantee our flowmeters will not be damaged either at or below the
suggested limits simply because of many factors which influence meter integrity;
stress resulting from meter misalignment, damage due to excessive vibration
and/or deterioration caused by contact with certain chemicals as well as direct
sunlight. These situations and others tend to reduce the strength of the materials
from which the meters are manufactured.

Application Note

Flowmeters are tested and calibrated for water or air only.

Although meters may be suitable for other chemicals, Blue-White
cannot guarantee their suitability. It is the responsibility of the user
to determine the suitability of the flowmeter in their application.

Maintenance

The “Exploded View” drawing illustrates assembly of the F-451 series meter. If
your flowmeter needs to be cleaned refer to this drawing when reassembling the
unit. The tapered tube may be cleaned with a soft bottle brush. Use a MILD soap
and water solution for cleaning purposes. Hard water deposits can be removed
with a 5% acetic acid solution (vinegar). Note the floats “up” position.
