Teledyne ISCO LevelRay Radar Sensor

Teledyne ISCO’s LevelRay non‑contact radar level sensor uses FMCW (Frequency Modulated Continuous Wave) method to measure liquid level. Mounted above the flow, it sends a linearly frequency‑swept radar signal and receives the reflection from the liquid surface. The slight time delay between transmitted and reflected signals creates a beat frequency proportional to distance, allowing the device to calculate level accurately. This non‑contact method minimizes maintenance and performs reliably in applications with 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.
