  • 6P rated for corrosive liquids
  • Fast & accurate configuration

EchoPod DL34 Ultrasonic Level Sensor

The EchoPod DL34 is a general purpose, ultrasonic level sensor providing non-contact level detection up to 5 m with 4 SPST 60 VA 1A relays and a two-wire 4-20 mA level measurement output. Each relay can be configured on a single set point alarm or latched on two sets for automatic fill or empty in simplex or duplex control modes with fail-safe logic. The embedded controller can replace external control hardware. The sensor is well suited for a wide range of corrosive, sticky, or dirty type media.

 Features of the EchoPod DL34 Ultrasonic Level Sensor include:

  • Multi-function sensor provides 4-20 mA measurement, switch, and control functions.
  • Compact sensor with 3″ beam width and 8” dead band optimized for small tank applications.
  • Four 1A relays programmable for switch or advanced pump or valve control and fail safety.
  • Rugged PVDF transducer and polycarbonate enclosure rated 6P for corrosive applications.
  • WebCal, an innovative PC user interface that provides fast and accurate configuration.

The EchoPod DL34 is ideally suited for:

  • Atmospheric day tank level
  • Process vessels or dispensers
  • Waste sumps
  • Pump lift stations
  • Mini-bulk storage applications
  • Small tank applications
