EchoWave® LG10 / LG11 Guided Wave Radar Level Transmitter





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