Installation Hardware
ONICON F-5400 Insertion Thermal Mass Flow Meters employ a process adapter
fitting design that allows for insertion and removal without interrupting flow. 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" hole 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 purging 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.
Important 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.
