Product Description

Geolux LX-80 series of instruments are advanced contactless radar level meters designed for precise distance measurement from the instrument to the surface of the various fluids.

This functionality is achieved by transmitting an electromagnetic wave in 80 GHz frequency range (W band), and measuring the frequency shift of the electromagnetic wave reflected from the water surface. Instruments are characterised by low power consumption, supported by multiple communication interfaces, compatible with Geolux and third-party dataloggers, and support remote configuration of all instrument settings over any available digital communication interface. Narrow beam width of only 5° allows for simpler installation, and that nearby structures such as bridge railings or pillars do not interfere with the accuracy of the water level measurement.
