Thermo-Flo™ with Compact Flow Controll
#157 in Flow Sensors
-
Application
-
The general purpose ultrasonic level transmitter provides continuous level measurement up to 9.8’ (3m) with a 4-20 mA signal output, and is configured via our free Webcal software. The level sensor has 4 programmable relays with selectable hysteresis and fail-safe logic. The embedded level controller can lower cost by replacing external control hardware. This non-contact liquid level sensor is ideally suited for corrosive, sticky or dirty liquids, and is widely selected for day tank, skid, IBC, sump and process tank level applications.
