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

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

Caution: Follow these tips to avoid failure.
Danger: Wear eye protection when

installing or removing flowmeter.

Flowmeter must be installed in an

exact vertical plane to ensure
accuracy. Use Teflon® tape (or
similar) for the flowmeters threaded
adapters.

2. Hand tighten union nuts. No

to support the weight of related piping
or tubing.

4. Valves - 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. Magnet, solenoid, or other quick
opening valves cannot be used unless
meter is protected against sudden
bursts of flow.
Maximum working pressure not to

exceed recommended psi at fluid
temperature (see Temperature Vs.
Pressure chart).

Blue-White® guarantees the meter is
suitable with air and water only.

* Your flowmeter has been designed to be virtually maintenance free. Should your
unit need occasional cleaning, use a mild soap and bottle brush.

* Be sure to note the floats "UP" position before disassembling the meter.
Cleaning: The flowmeter body and all other parts can be cleaned by washing in a

mild soap and water solution. A soft bristle brush will simplify cleaning inside the
meter body. Note the floats up position for re-assembly.

Pressure and Temperature

Pressure and temperature limits are inversely proportional. At the maximum
suggested pressure the temperature should approach 70°F / 21°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.

Flowmeters are tested and calibrated for water or air only.

Although meters may be suitable for other chemicals, Blue-White cannot guarantee their suitability.
