Ultrasonic Flow and Bubble Sensors for Liquids

Non-contact liquid measurement on rigid and flexible tubing plays an important role in a large number of applications with highest sterility and hygiene requirements and purity demands.

Non-invasive flow meters and air bubble detectors are key components in the semiconductor industry, in bioprocessing applications, and are widely used in medical technologies.

Product Portfolio

Areas of Application

Expertise

Liquid Flow Measurement

High-precision SONOFLOW and SEMIFLOW flow sensors are used for non-contact liquid flow monitoring. They measure and control flow velocities, flow rates, and flow volume as well as dosing processes.

Air Bubble Detection

Sensors in the SONOCHECK ABD series are designed for contact-free air bubble detection in liquid-filled tubes. They also assume tasks for full / empty monitoring.

Calibration Service & Repair

To maintain the original performance and accuracy of our products, we recommend recalibrating our sensors every 12 months. In addition to recalibrating our flow sensors, we offer safety inspections and repair services for all our ultrasonic products.
