The PiloTREK series of level gauges are simple devices that work according to the radar method. The principle of operation is based on measuring the transit time of reflected pulses. The propagation velocity of microwave pulses is practically the same in air, gas and vacuum, regardless of the temperature and pressure of the process, so the measured distance is not affected by the physical properties of the measured medium. The level gauge induces microwave pulses lasting several nanoseconds in the antenna, and part of the energy of the emitted signals is reflected from the surface of the measured mass, depending on the characteristics of the measured medium. The flight time of the reflected signal is measured and processed by electronic devices, and then this value is proportionally converted into distance, level or volume data.
PiloTREK25 Hz pulse radar sensors (K band) are considered the most advanced non-contact level meters in the field of industrial process automation. Now a new product is available for order: PiloTREK with a flange and a parabolic antenna made of stainless steel DN150 and a measuring range of 15 - 23 m. Such a level gauge is ideal for measuring media with a low dielectric constant, since it has a scattering angle of 6° (dead zone of 0.4 m). Such indicators can be compared with the indicators of high-precision level meters built on the ultrasonic measurement principle.
