Turbine Flow Meter Manual 05/14 - 0721-3 / 13518 Page 12

3.3 INSERTION METER MECHANICAL INSTALLATION

ONICON Insertion Turbine Flow Meters employ a hot tap adapter design that allows for

insertion and removal, when necessary, without interrupting ow and draining the pipe. To take

advantage of this feature, the ow meter must be installed through an isolation valve. The

installation must also allow for sufcient overhead clearance to fully extract the meter, and a full

1” opening in the pipe wall is required to clear the sensor head and allow for insertion. Make sure

that your valves and ttings are full port and at least 1” in actual internal diameter.

CAUTION

ONICON insertion style ow meters must be installed through a valve assembly. Failure to do so

negates the ability to remove the meter without shutting down ow and draining the system. It will

also result in an excessive amount of stem protruding from the pipe. Excessive stem lengths

unneccessarily 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.
