OMEGA’s LVCN318 ultrasonic level transmitter and controller provides continuous level measurement up to 5.5 m (18') with a 4 to 20 mA signal output, and is configured via our free software via a USB adaptor. 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.
