A new range of radar level gauges based on advanced radar technology (FMCW) is about to be launched. There are three versions designed to be used in both simple and complex measuring applications. The radar level gauges claimed to be very reliable even under severe conditions, such as turbulence, or high temperatures and pressures. As a result, their sensitivity is much greater than that of earlier systems, according to Saab Tank Control AB, the Swedish company that developed the instrument.
