Geolux - Model LX-80 -Radar Level Sensor
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.
- Contactless water level measurement
- The narrowest beam measurement angle on the market (5°)
- RS-232, RS-485 Modbus, SDI-12, analog 4-20 mA interfaces in all models
- Remote configuration of all instrument parameters through any digital communication interface
- Robust small size IP68 aluminum or stainless steel enclosure
- Water level monitoring for rivers, channels and lakes
- Early flood warning
- Water reservoir monitoring and irrigation control
- Observing the level of various fluids in the chemical industry
- Fluid and solid level tracking in the food industry
- Monitoring levels in waste water, industrial applications, and tanks
