The Type F111 Hot-Tap Flow Sensors may be removed and reinstalled while the pipe is under pressure. A square wave output signal is generated with frequency proportional to rate of rotor rotation and flow velocity. This pulse output is normally fed to a FlowX3 flow monitor/transmitter, blind transmitter, batch controller or adjustable flow switch. It can also be fed to other brand instruments or PLC’s.

Two types of sensors are available, Hall Effect which requires a 5 to 24 VDC power supply and Coil Effect which operates with less power, 3 to 5 VDC. Coil is required with the battery powered flow monitor. Hall Effect signals may be transmitted up to 300 meters (984 ft.) without the need for conditioning whereas Coil Effect signals may be transmitted up to 16 meters (52.5 ft.) without conditioning.
