!

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

!

Carefully inspect the meter for any damage that may have occurred during shipping.

!

Remove the plastic tubing that has been inserted during packaging for shipping
reasons.

!

Make sure your pressure, temperature, fluid and other requirements are compatible
with the meter before installation.

!

The maximum temperature capability decreases as the pressure increases. The max
PSI decreases as the temperature increases. See the chart on the following page.

!

Although the meter may be suitable for other chemicals, Blue-White meters are tested
with water. If you are unsure of the meters compatibility with your chemical, please
consult the factory.

!

Blue-White warranties the flowmeter for use with water only.

Installation Guideline

Caution: Follow these instructions to
avoid failure.

Ceiling

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
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 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-450 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.
