Fast, Reliable and Non-invasive: Sensors for Contactless Flow Measurement

SONOFLOW contactless flow-rate measurement

In medical technology many sensitive fluids are used that should not be contaminated any circumstances. The flow rate of medicines and blood preparations has to be monitored with utmost care as well. Sensors are required that provide precise measurement values without coming in contact with the corresponding medium.

The contactless SONOFLOW sensors by SONOTEC Ultraschallsensorik Halle GmbH fulfill exactly the aforementioned criteria. They are made of different materials (e.g. aluminum, stainless steel, plastics to accommodate any situation) and are simply clamped-n the tube with the flowing medium. This ensures that fluids cannot been contaminated by the sensor housing. Additionally, the sensor does not require sterilization. Therefore, the SONOFLOW sensors are especially suited for applications with highest hygienic requirements.

The handling of the ultrasonic sensors is simple: An external electronic board is not needed as the electronic signal processing unit is directly integrated into the housing of the sensor.

The clamp-on sensors of the SONOFLOW series are applicable for various tubing types and materials, for example PVC, silicone, PFA or PTFE. They are available for all tubing diameters and can be customized to individual applications on request.

In addition to the approved features – like fast measurement of pulsating and bi-directional flow rates – SONOTEC equipped the sensor SONOFLOW CO.55 in the version 2.0 with a volume switch. The flow meter is now able to perform small control tasks. It can even stop a connected dosing pump after a predefined amount of liquid passed through the tube.

Besides the flow sensor series SONOTEC offers the combined sensor SONOFLOW CO.56. This sensor is able to measure the flow rate by simultaneously detecting air bubbles in the flowing liquid.
