The optimised ultrasonic limit switch Sonocontrol 15 from Sonotec (Germany) detects quickly and reliably whether or not a pipe is filled with liquids or liquid gases. The compact sensor is widely used in petrochemical plants. Here, the Sonocontrol 15 is employed for the protection of pumps and the control of filling systems.

The known advantages of the limit switch, such as the non-intrusive ultrasonic measurement through the wall as well as the precise distinction between empty and liquid filled pipes, have been upgraded by further favourable characteristics. The simplified installation method of the 2-wire system for example, which can be carried out even during system operations, guarantees an optimal use of the device. Due to a new pipe fastening system made of plastics, the sensor can be relocated quickly and easily. Furthermore, the advanced firmware assures a stable operating mode.   The required power supply is 12 to 40 VDC. According to the 4 to 20mA concept, the switching status is represented by the current consumption of the sensor. The acceptable medium or pipe temperature range lies between –40°C to +140°C. A version of the Sonocontrol 15 is also available specifically for use in hazardous areas.
