The Bell & Gossett Circuit Setter® 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 flow meter orifice by sensing upstream and downstream pressures through the readout valves, then referring to the calibrated nameplate for the corresponding flow. Circuit Sensor® Flow Meters are suitable for a maximum operating temperature of 250 deg F (121 deg C), and are equipped with RV-125A Readout Valves fitted with an integral EPT check valve designed to minimize system fluid loss during the monitoring process.
