EchoPod® DL24 Multi-Function Ultrasonic Level Transmitter














The general purpose ultrasonic level transmitter provides continuous level measurement up to 9.8' (3m) with a 4-20 mA signal output, and is configured via our free WebCal software. The level sensor has 4 programmable relays with selectable hysteresis 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 widely selected for day tank, skid, IBC, sump and process tank level applications.


 Switch and control functions with continuous level measurement output up to 9.8' (3m)

 Configuration is fast and easy via WebCal software and USB adapter

 Narrow 2" beam width and short 4" dead band optimized for day tanks

 Four (4) programmable relays rated @ 1A / 60VA for switch, pump or valve control and fail-safety

    1 pump or valve with 3 alarms

    2 pumps (lead-lag) with 2 alarms

     2 pumps (duplexing) with 2 alarms

    4 independent switch point alarms

 PVDF transducer and 6P polycarbonate enclosure for corrosive liquids

 Automatic temperature compensation for accurate measurement
