The general purpose ultrasonic level switch provides continuous level detection up to 49.2" (1.25m) with 4 programmable relays for level switch or level control functions, and is configured via our free WebCal software. 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 broadly selected for small day tank, skid, IBC, sump and process tank level applications.
