For Precise Measurement of Low Volume Flow Rates in Thin Pipes and Tubes

The precise ultrasonic flow sensor SONOFLOW IL.52 detects smallest flow rates of liquids quickly, using bidirectional measurement. Due to its construction and its resistance to temperature the sensor is particularly suitable for applications in fi elds with strict hygienic standards. An additional benefit is, that the sensor is wear- and maintenancefree.

The SONOFLOW IL.52 is constructed as a built-in component for machines and apparatus.
The mechanical installation and electrical integration into the control system can be carried out easily. The sensor has two current outputs or pulse outputs respectively. The service interface allows an easy parameterization, calibration and readout of measuring values.

In addition to our standard products, we can also manufacture customer-specific solutions.
