ETG - Model RLS - Radar Hydrometric Level Sensor - Brochure

The RLS is a two-wire level transmitter operating with 6 GHz radar pulses for measurement ranges up to 20 m. It lends itself to the continuous monitoring of liquids and sludge in non-pressurised storage tanks in normal environmental conditions. The RLS is suitable for applications with chemical vapours, temperature gradients, vacuum or pressure, for example in tank farms, in storing chemical substances, in digestion towers or in sludge tanks. ETG RLS has a measurement range from 0.3 up to 20 m. The design of the RLS offers simple programming with the intrinsic security hand-held programming device, also without opening the cover of the instrument in the Ex area. The rod antenna in polypropylene offers high chemical resistance and is made as a single watertight piece. It has an integrated internal shield that eliminates disturbances coming from the assembly structure. The high signal/noise ratio of the RLS guarantees optimum reliability. The level measurement contains level switches and protection against overflow, empty signalling and protection against dry operation.
