Compact Clamp-On Sensor for Non-invasive Flow Metering in Tubes

The ultrasonic flow sensor SONOFLOW CO.55 quickly detects the flow rate of liquids in tubes. Due to its construction the non-invasive clamp-on sensor is particularly suitable for applications in fields with strict hygienic standards. The tube is easily put into the sensor and enables a smooth and uncomplicated change.

Unlike all other on the market available sensors the complete evaluation is integrated in the sensor, so that no additional external electronic board is required. This increases the user’s flexibility in terms of its product design. The number of deployed sensors is variable, without blocking valuable space in the system.

The SONOFLOW CO.55 is constructed as a built-in component for machines and apparatus. The electrical integration into the control system can be carried out easily. The sensor has got a configurable current or pulse output. The service interface allows an easy parameterization, calibration and readout of measuring values. This method can be adapted to individual tube sizes as well as other specifications, such as different voltages, switching outputs or material characteristics.

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