LEVEL SENSORS

The general purpose ultrasonic level transmitter provides continuous level measurement up to 18.0′ (5.5m) with a 4-20 mA signal output, and is configured via 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 from 1.25m to 5.5m
  • Configuration is fast and easy via WebCal software and USB adapter
  • Narrow beam width and short dead band optimized for small 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

H2trOnics recommends the Flowline EchoPod® series of level transmitters for accurate and reliable level sensing. The DL34, DL24, and DL14 models serve a wide range of configurations as displayed in the specification table below:
