IMPORTANT : All flow lines should be purged prior to installing the
meter. To prevent possible damage to the meter, install the
meter ONLY in flow lines that are clean and free of debris.
Upon initial start-up of the system a spool piece should be installed
in place of the flowmeter so that purging of the system can be
performed to remove all particle debris which could cause damage
to the meter internals. In applications where meter flushing is
required after meter service, care should be taken as to not over-
spin the meter, as severe meter damage may occur.
CAUTION : Avoid over-spinning the meter. Over-spinning the meter may
result in damage to the meter internals and lead to meter
failure.
3.2 Strainers/Filters
The Omega FTB500 Series of Low Flowrate Meters is designed
for use in a clean fluid service. However, the service fluid may
carry some particulate material which would need to be removed
before reaching the flowmeter. Under these conditions a
strainer/filter may be required to reduce the potential hazard of
fouling or damage that may be caused by foreign matter.

If a strainer/filter is required in the system, it should be located
upstream of the flowmeter taking care that the proper minimum
distance is kept between the strainer and flowmeter.
3.3 Installation Kits
