The KROHNE OPTISOUND 3050 C Ultrasonic Level Gauges are especially suitable for level measurement of solids, but are also good for liquids. The instruments offers measuring ranges of 0.8 to 45m (2.6 to 147.6ft) for liquids and 0.8 to 25m (2.6 to 82ft) for solids.

Resistant materials for the transducers and process fittings also allow applications in corrosive products (depending on the model).

Short ultrasonic pulses in the range of 18 kHz to 35 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.

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.

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.
