•  Simplex, duplex & triplex options
•  Integrated timer for pump/valve
•  NEMA 4X rated enclosure
 

The EchoSwitch LU74 through to LU78 Series general purpose ultrasonic level sensor provides continuous level detection up to 26.2’ (8m). The EchoSwitch from Flowline has 3 programmable relays for level switch or level control functions, and a 4-20mA signal output.
 
EchoSwitch II features digital push button configuration, eliminating target calibration. Each relay can be configured on a single set point to control pumps, valves or alarms. In addition, all 3 relays can be simplexed, duplexed or triplexed.
​
EchoSwitch II now features an integrated timer with pump/valve delay and timed pump alternation. The switch is well suited for a broad range of corrosive, waste and slurry type media and is broadly selected for atmospheric day tanks, pump lift stations and waste sump applications.
 
Features of the EchoSwitch LU7 Ultrasonic Level Switch include:
 

• Simple digital push configuration, no more target calibration
• Available in 2.5m or 7.5m range
• 10cm miniature dead band optimises the filling capacity of sumps or vessels

Multi-Point Ultrasonic Level Switch and Controller.The ideal float switch replacement providing non-contact level detection up to 7.5m with 3 relays for advanced pump, valve and alarm automation functions.
