Choice of Three Port Sizes: Select from 1/2” , 3/4” or 1” NPT porting to meet system requirements. NOTE: Using reduced ID fittings will affect calibrated range.

Encapsulated Circuitry: Withstands the harshest environments.

Several Outputs Available: The standard interface is a 2-wire, 4-20mA current loop. Sensor signal may be transmitted on a low cost wire without degradation. Pulse, relay and 0-5 VDC (regulated) are also available.

Connects Directly to your Flow Monitoring Instruments: Can be connected directly to analog acquisition cards, chart recorders or other monitoring instruments, without external signal conditioning.

Simply Plumb and Apply Power: Comes factory calibrated to your flow range specifications.
