The general purpose ultrasonic level sensor provides continuous level detection up to 26.2 (8m) with 3 programmable relays for level switch or level control functions, and a 4-20mA signal output. The sensor is programmed via the integral push button display module. Each relay can be configured on a single set point alarm or latched on two set points for automatic fill or empty in simplex, duplex or triplex level control modes with selectable time delay 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 broadly selected for pump lift station, sump and day tank level applications.
