LX-80 Water Level Radar Sensor

Name: LX-80 Water Level Radar Sensor
SKU: LX80-Series

The Geolux LX80 instruments are a cutting-edge solution for contactless radar-based water level measurement. Operating in the 80 GHz frequency range (W band), the LX80 instruments transmit modulated electromagnetic waves and measure the frequency shift of the waves reflected from the water surface. The measured freqeuncy shift accurately corresponds to the distance between the instrument and the water surface, which the instrument reports.

Features

Contactless, highly accurate, water level measurement.
Narrowest beam measurement angle on the market (5°).
RS-232, RS-485 Modbus, SDI-12, and analog 4-20 mA interfaces included in all models.
Remote configuration of all instrument parameters through any digital communication interface.
Robust, small-sized IP68 aluminum or stainless steel enclosure.

Description

The LX80 is engineered for low power consumption, making it suitable for remote and long-term deployments. It offers multiple communication interfaces, including RS-232, RS-485 Modbus, SDI-12, and analog 4-20 mA, ensuring compatibility with both Geolux and third-party dataloggers. Additionally, all instrument settings can be remotely configured via any available digital communication interface, allowing remote reconfiguration of the instrument’s operating parameters.

A key feature of the LX80 is its exceptionally narrow beam width of just 5°. This focused beam allows for simpler installation and ensures that nearby structures, such as bridge railings or pillars, do not interfere with the accuracy of the water level measurement. It also allows for installation in existing stilling well structures.

The instrument is designed for continuous non-contact water level monitoring in hydrological networks according to WMO-No. 168.
