2.
Seat the meter level and square on the mating connections with the flange
stamped with a flow arrow on the upstream side, with the arrow head
pointing in the direction of flow. Position a gasket in place for each side.
Make sure both gaskets are smooth and even with no gasket material ex-
tending into the flow profile. Obstructions in the pipeline will disturb the
flow and cause inaccurate measurements.
3. Install bolts in both process connections. Tighten the nuts in the se-
quence shown in Figure 2-2. Check for leaks after tightening the flange
bolts.
Series M23 Insertion Flow Meter Installation
Prepare the pipeline for installation using either a cold tap or hot tap
method described on the following pages. Refer to a standard code for all
pipe tapping operations. The following tapping instructions are general in
nature and intended for guideline purposes only. Before installing the me-
ter, review the mounting position and isolation value requirements given
below.
Mounting Position
Allow clearance between the electronics enclosure top and any other ob-
struction when the meter is fully retracted.
Isolation Valve Selection
An isolation valve is available as an option with Series M23 meters. If
you supply the isolation valve, it must meet the following requirements:
1. A minimum valve
bore diameter of
1.875 inches is re-
quired, and the
valve’s body size
should be two inches.
Normally, gate
valves are used.
2.
Verify that the
valve’s body and
flange rating are
within the flow meter’s maximum o perating pressure and tempera-
ture.
3.
Choose an isolation valve with at least two inches existing between
the flange face and the gate portion of the valve. This ensures that the
flow meter’s sensor head will not interfere with the operation of the
isolation valve.
