APPLICATION NOTES
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.
Flowmeters are tested and
calibrated for water only.
MAINTENANCE
The “Exploded View” drawing illustrates assembly of the F-451N 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. Note the
float’s “up” position.

1 The flowmeter must be installed in a
vertical plane to ensure accuracy.
Misalignment may damage the flowmeter
and also may cause the o-ring seals to leak.
2 Use only PTFE tape on the threaded
adapters.
Pipe dope and glue will damage
the polysulfone meter body and fittings. Or
install the flowmeter after all glued fittings
have dried and fumes have been purged
from the system.
3 Mounts and supports must be sturdy
enough to support the plumbing and
prevent vibration.
Vibration and heavy
loads will damage the meter.
4 Avoid imposing a sudden burst of flow
to the meter.
Solenoid valves will damage
the meter. Such a burst will cause the float to
impact the top float stop with destructive
force.
5 The Maximum fluid temperature is
dependant on the working pressure.
High
pressure and temperature with damage the
meter. (see temperature VS pressure chart)
