LU74-5004, Flowline EchoSwitch Series, Ultrasonic Level Switch Vertical Mounting Ultrasonic Level Sensor

Flowline Ultrasonic Level Switch

The Flowline Ultrasonic level sensor provides continuous level detection up to 26.2ft (8m) with 3 programmable relays for level switch or level control functions and a 4mA to 20mA signal output. This sensor is programmed via the integral push button display module. Each relay can be configured on a single set point (high-level alarm or low-level alarm) or latched on two set points for automatic fill or empty in simplex (one pump or valve), duplex (two pumps) or triplex (three pumps) 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.
Note:
Compatible with Various Flowline product ranges such as DataLoop, DataView, DataPoint and Commander
