Tides Sensors

The RADAR level sensor model RADAR 6115/6135 provides distance measurements based on the running time of microwave pulses transmitted to and reflected from the surface of the water, snow or other liquid and solid surfaces. Our RADAR 6115/6135 Level sensor operates in the time domain, using a high pulse repetition frequency (PRF) and therefore it does not require FFT analysis, that characterizes FM or CW radars. Pulse RADAR operates purely within time domain.

Tides Sensor

Millions of pulses are transmitted every second and a special sampling technique is used to produce a “time expanded” output signal. The Microwave transmitters are virtually unaffected neither by temperature nor atmospheric pressure, air density, winds or any other weather conditions. The RADAR technology is intrinsically very accurate, also allowing a broad margin of programmable measurement ranges (up to 35 meters programmable), perfectly adapted to the site requirements. GEO-CONNECT System for configuration and adjust in the field by means of a PC.

Our RADAR level sensor has an accuracy of 2 mm in the whole range for individual measurements, and 1 mm for averaged values when connected to our Data Loggers METEODATA/HYDRODATA. This accuracy cannot be achieved by ultrasonic technology, as when the weather conditions vary, the ultrasound becomes more vulnerable to large errors and erratic readings.
