Owner’s Manual for ONICON Insertion Turbine Flow Meters • September 27, 2001

• Installing the meter with a factory supplied
depth gage:
1. Open valve completely, loosen the
position clamping nut, and insert the
meter until the bottom of the electronics
case touches the eye of the depth gage.
(Pierce insulation with gage until the tip
touches the pipe.)
2. Position the electronics enclosure parallel
to the pipe in the direction relative to the
flow. This will position the turbine with
its axis in line with the flow and in the
correct direction.
3. Tighten the position clamping nut.
Do not release the flow meter until you have tightened the position clamping nut
enough to hold the flow meter in the desired position. This will require less torque
than you might think, so be careful not to overtighten it and risk damaging the
adapter, nut or stem.
• Installing the meter without a gage: (Contact the factory for assistance)
NOTE: For installations with a limited straight run of pipe (less than the recommended
distances shown on pages 9 and 10),adjustments in insertion depth may be needed to
compensate for velocity flow profile variations. Please contact the factory for information on
velocity flow profiling for determining the average velocity location in undeveloped flow
locations.
3.4 REMOVAL OF THE METER
***CAUTION***
Remember, the meter may be under high pressure, and while removal of the meter is
basically the reverse of the insertion procedure detailed above, care must be taken to
ensure that the meter is supported against the pipe pressure before the position
clamping nut is loosened. Failure to do this will allow the pressure to suddenly and
rapidly force the meter from the pipe causing serious injury.
Prior to removal of the meter, make sure that you are standing on a secure platform
and have both hands available to manipulate the flow meter.
