3 Instruction Manual
Meter Body
The flowmeter should be lifted by a rope sling being passed around the outside of the meter or,
in the case of the large meters the lifting lugs should be used. Never pass a cable or beam
through the flowtube for lifting purposes, as this will damage the flowtube liner and render the
meter unusable. Do not support the meter by its case.
Check for alignment and spacing of pipe work, as the meter should not be used to pull pipe
work into alignment. Table overleaf gives face to face and overall dimensions for the various
sizes and types of meter.
Place flange gaskets on the flange faces of the meter and position the meter between the
flange faces of the piping. Gaskets should be cut 3 mm larger than the inside diameter of the
pipe.
Insert bolts through the flanges and run washers and nuts onto the bolts. Check the piping for
alignment and the gaskets for concentricity. Tighten the nuts evenly – do not over tighten as
this may damage the liner. Bolt torque should be limited to that which will produce a positive
seal.
Application Guidelines
1. The velocity at maximum flow should be greater than 1 m/s. (select the meter size
accordingly)
2. The minimum flow velocity the flowmeter will measure is 0,1m/s.
3. The maximum velocity the flowmeter will measure is 10 m/s
4. The conductivity of the liquid should be greater than 20μs/cm.
