Pressure Temperature and
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. It is the responsibility of the user
to determine the suitability of the flowmeter in their application.
Application Note
Maintenance
The “Exploded View” drawing illustrates assembly of the F- 462 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.
