Flowline LU77-5064 EchoSwitch Ultrasonic Level Switch & Controller 3m (9.8'), 95-250 VAC, 2" G

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.

Features:

• Offered in 3 level detection ranges from 9.8' (3m) to 26.2' (8m)
• Configuration is simple via integral push button display module
• Three programmable relays for switch, pump control and fail-safety
  • 1 pump or valve with 2 alarms
  • 2 pumps lead-lag with 1 alarm
  • 2 pumps duplexing with 1 alarm
  • 3 independent switch point alarms
• 4-20 mA output provides local or remote process level monitoring
• LCD display indicates level height in engineering units and relay status
• Narrow 2" or 3" beam width for applications with limited space
• Short 4" or 8" dead band maximizes the filling capacity of the tank
