The preferred plumbing setup is one containing a by-pass line
(Fig. 3) that allows meter inspection and repair without interrupt-
ing flow. If a by-pass line is not utilized, it is important that all
control valves be located down-stream of the flow meter (Fig. 4).
This is true with any restriction in the flow line that may cause
the liquid to flash. If necessary, air eliminators should be in-
stalled to ensure that the meter is no incorrectly measuring en-
trained air or gas.
It is recommended that a minimum length, equal to 10 (10) pipe
diameters of straight pipe, be installed on the up-stream side and
five (5) diameters on the down-stream side of the flow meter.
Otherwise meter accuracy may be affected. Piping should be the
same size as the flange size.
Do not locate the flow meter or connection cable close electronic
motors, transforming, sparking devices, high voltage lines, or
place connecting cable in conduit with wires furnishing power for
such devices. These devices can induce false signals in the flow
meter coil or cable, causing the meter to read inaccurately.
If problems arise with the flow meter and monitor consult Appen-
dix A (Trouble Shooting Guide). If further problems arise, con-
sult factory. Turbine Meter Repair Kits are also available, see
Appendix C. If the internal components of the turbine flow me-
ter are damaged beyond repair, these repair kits are available.
Information pertaining the turbine meter repair kits are referenced
in Appendix C.
Caution: Damage can be caused by striking an empty me-
ter with high velocity flow stream.
