The Krohne OPTISOUND 3020 C Ultrasonic Level Gauges are especially suitable for level measurement of liquids, but are also good for solids. The OPTISOUND 3020 C offers measuring ranges of 0.4 to 8m (1.3 to 26.2ft) for liquids and 0.4 to 3.5m (1.3 to 11.5ft) for solids.
Short ultrasonic pulses in the range of 35 kHz to 70 kHz are emitted by the transducer to the product surface, reﬂected there and received by the transducer. The pulses travel at the speed of sound - the elapsed time from emission to reception of the signals depends on the level in the vessel. By simply entering the vessel dimensions, a level-proportional signal is generated from the distance. It is not necessary to ﬁll the vessel for adjustment.
The latest microcomputer technology and the proven processing software select the level echo from among any number of false echoes and calculate the exact distance to the product surface. An integrated temperature sensor detects the temperature in the vessel and compensates the inﬂuence of temperature on the signal running time.
