INSTALLATION
There are no upstream or downstream piping requirements to achieve the operating specifications given
herein. The meters may be installed in any position as long as good piping installation requirements are
adhered to for best results. This includes proper support of adjacent piping to minimize inherent vibra-
tions produced within the system. Unions of the same pipe size and full port isolation ball valves may be
installed for ease of removal and servicing of equipment, if required. Meters should be placed in hori-
zontal, slightly ascending runs or vertical runs to prevent entrained air from accumulating in the
meter. They should not be placed at the highest point in the piping for this same reason. Piping system
should be filled slowly to prevent water hammer from damaging sensor. The meter sensor can also be
damaged by reverse flow.
Isolation ball valves, when used, should be in the full open position. Throttling valves should always be
placed downstream of the meter, a minimum of 10 pipe diameters downstream.
Teflon
®
tape or pipe sealant can be used in mounting the meter to the piping when using good technique.
Teflon
®
tape, if not applied properly to the connecting piping, can become caught on the bluff and affect
the flow measurement.
Use of diaphragm or piston pumps will affect metering performance, unless they are installed with a
properly sized pulsation dampener and pressure control valve, to minimize pulsating flow. The piping
system must create some backpressure on the meter to allow vortex formation and to prevent cavitation,
especially at full flow. Minimum required back pressure is 10 PSIG at max flow and 70
°
F (21
°
C).
Higher back pressures are required at elevated temperatures and occasional surges to 125% of max flow.
This situation will not be encountered in most installations. If while increasing the flow, the signal or
displayed flow appears to drop off, but reappears when flow is reduced, contact OMEGA to determine
back pressure requirements to extend the flow range to the capacity of the meter.
