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 situa-
tions and others tend to reduce the strength of the materials from which the meters are manu-
factured.
Flowmeters are tested and calibrated for water or air only.
F-420 Meter Installation
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
Please use the following steps to guide you through the
installation.
1.
Flowmeter must be installed in an exact vertical plane to
ensure accuracy.
2.
Use Teflon® tape (or similar)for the flowmeters threaded
adapters. Acrylic and other exotic plastics cannot
tolerate PVC Glue and/or pipe dope. Even fumes can
cause crazing. If you are installing your flowmeter to a
glued pipe configuration, install flowmeter
after
all
glued fittings are dried and lines are purged of all
fumes.Never hold the meter with pliers or like tools.
DO NOT OVER-TIGHTEN!
3.
Wall, floor and ceiling mounts are to be carefully aligned and sturdy. Wall, floor and ceiling
supports are recommended as needed.
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. Solenoid valves,
or other quick opening valves cannot be used unless meter is protected against sudden
bursts of flow.
5.
Maximum working pressure not to exceed recommended psi at fluid temperature (see
Temperature Vs. Pressure chart).
Caution:
Follow these tips to avoid failure
Danger:
Wear eye protection when installing or removing
flowmeter.
