- Level measurement during processing and storage of liquids
- Sumps, water and wastewater basins
- Noncontact flow measurement and detection in open channels
Short ultrasonic pulses in the range of 35 kHz to 70 kHz are emitted by the transducerto 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 in fluence 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.
Wide application range:
OPTISOUND 3010C, 3020C and 3030C ultrasonic sensors are especially suitable for level measurement of liquids, but are also good for solids. The instruments differ inthe measuring range, the transducer version and the process fitting. Through different, adapted emitting frequencies, levels in a measuring range of 5...15m (16.4...49.2ft) can be measured. Resistant materialsfor transducers and process fittings also allow applications in corrosive products (depending on the model). Apractical mounting strap (option) enables easy orientation of OPTISOUND 3030C.
Unaffected by product properties:
Fluctuations in product composition or even complete product changes do not in fluence the measuring result. A fresh adjustment is not necessary.
Service and maintenance friendly:
Thanks to the non-contact measuring principle, OPTISOUND sensors are particularly easy to service and maintain.
