Installation Hardware
ONICON F-5500 Insertion Thermal Mass Flow Meters employ a process adapter fitting
design that allows for insertion and removal, when necessary, without interrupting
flow and draining the pipe. To take advantage of this feature, the flow meter must be
installed through an isolation valve. The installation must allow for sufficient overhead
clearance to fully extract the meter, and a full 7/8" opening in the pipe wall is required
to clear the sensor head and allow for insertion. Make sure that your valves and fittings
are full port and at least 1" in actual internal diameter.
Fig. 2.2: Installation Requirements
CAUTION! ONICON insertion style flow meters must be installed through a valve
assembly. Failure to do so negates the ability to remove the meter without shutting
down and draining the system. It will also result in an excessive amount of stem
protruding from the pipe. Excessive stem lengths unnecessarily expose the meter to
incidental damage.
NOTE: Flow meters installed through oversized access holes will be subjected to
undesirable turbulence that may affect the accuracy of the meter.
Flow Conditioners
Flow conditioners may be required when an insufficient straight run of pipe is available
upstream of the proposed sensor location. ONICON provides flow conditioners as an
optional accessory.
