Teledyne ISCO Water’s LevelRay non-contact level sensor uses FMCW (Frequency Modulated Continuous Wave) technology to remotely measure liquid level. The sensor is mounted over the flow stream, transmitting and receiving radar waves that are reflected off the liquid’s surface. The elapsed time between transmitted and returned signals determines liquid level. The non-contact measurement method reduces the frequency of maintenance and is ideal for applications where the flow may contain chemicals, grease, silt, or suspended solids.
Submersible for continuous operation
In addition to working as a non-contact sensor using radar waves, the LevelRay’s rugged design and IP68 protection allow it to withstand being submerged. When a LevelRay is installed with the optional integrated pressure sensor, level measurement switches from radar to the pressure sensor upon submersion and continues providing level readings while submerged.
Quick and easy flow meter interface
LevelRay outputs level measurement using TIENet® or Modbus RS485 protocols. The TIENet protocol readily allows the LevelRay to interface with Teledyne ISCO DuraTracker or Signature flow meters for level and flow measurement. The flow meter calculates the flow using one of the built-in flow conversions or a user-defined level-to-flow relationship. Using Modbus protocol, LevelRay can be connected to a non-ISCO device for level and flow measurement.
