EchoWave LG10-11 Guided Wave TDR Liquid Level Sensor Transmitter


Offered in three probe types, the general purpose guided wave level transmitter provides continuous level measurement up to 18’ (5.5m) with a 4-20 mA signal output, and is configured via our free WebCal software. This liquid level sensor is applied in non-turbulent environments with foam, vapor, condensation, temperature or pressure. Select the rod or cable probe for use with clean, dirty, coating or crystallizing liquids in above grade metal or below grade tanks of any material. Select the coaxial probe for use with clean, non-coating or crystallizing liquids in above or below grade tanks of any material. Standard probe lengths may be user cut in the field. Typical applications include small bulk storage, day tank, skid or machine, IBC or drum, process tank, cooling tower and waste sumps.


  • Offered in standard or custom probe lengths up to 18’ (5.5m)
  • Configuration is easy via WebCal software and USB adapter
  • Rugged 316L stainless steel probe and process mount
  • 4” (10cm) dead band enables utilization of the entire tank
  • Disturbance scan maps and rejects false echo signal returns
  • Rugged NEMA 4 aluminum enclosure with 316L process mount
  • Self diagnostics with five selectable fail-safe signal outputs
