Guided Radar Level Meters

Guided Radar Level Meters

Guided Radar Level Meter uses time domain reflectometry for continuous measurement of liquids or solids. It's a cost-effective, higher-performing replacement for traditional level meters with an intuitive, five-step quick setup procedure that gives reliable measurements within minutes.

Guided radar level meter can measure the level of a wide range of liquid products on a large variety of installations within the stated pressure and temperature range, including LPG and LNG. It can be deployed in blending tanks, distillation tanks, process tanks, separators, solid silos (inventory) and storage tanks. It does not require calibration or commissioning when installed, and can measure liquid interface with or without an air gap.The level meter can also measure level and interface simultaneously as it has an optional second analog output. Lastly, the level meter can measure powders and granulates of materials with dielectric constants of 1.6 and even lower. A variety of rigid and flexible probes allow measurement in silos up to 35 m (115 ft) high.

Time domain reflectometry uses low-intensity electromagnetic pulses along a rigid or flexible conductor. These pulses move at the speed of light, and when they reach the surface of the product to be measured, they are reflected with an intensity that depends on the dielectric constant of the product. The device measures the time from when the pulse is transmitted to when it is received. The time value is converted into an output current of 4-20 mA and/or a digital signal corresponding to the level.
