Your Blue-White F-452N Series

!

Your Blue-White flowmeter was designed to be easy to
install.

!

Please read the Instruction Guideline on the next page
before installing your flowmeter.

!

This flowmeter is an instrument, special care should be
taken when handling and installing.

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 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 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).

Pressure and Temperature

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 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-452N 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.
