Flow Meter - Type A
Engineered Products
DESCRIPTION
The B&G Circuit Sensor Flow Meter is a precision machined wafer-type orifice
insert that is installed between standard 125, 150, 250 or 300 psi ANSI flanges, to
monitor system flow with a minimum friction head loss.
System flow is determined by obtaining a differential pressure across the flo
w
meter orifice by sensing upstream and downstream pressures through the readout
valves, then referring to the calibrated nameplate for the corresponding flow.
