Ultrasonic Flow Sensor - Marquardt

The Ultrasonic Flow Sensor enables precise and reliable measurement of liquid flow using ultrasonic technology.
In addition to flow rate and direction, the sensor detects air bubbles, particles and empty pipes, supporting efficient and reliable system control.

Ultrasonic Flow Sensor - Marquardt

The Ultrasonic Flow Sensor is designed for precise and reliable measurement of liquid flow. Using advanced ultrasonic technology and piezo elements, the sensor measures both flow rate and direction, providing accurate data for efficient system control.
In addition to flow measurement, the sensor detects air bubbles, particles and empty pipes. It also enables reliable measurement of liquids containing suspended solids and can detect the glycol concentration within the medium.
With no moving parts, the ultrasonic measurement principle provides high durability and low maintenance requirements. Customizable software as well as flexible electrical and mechanical interfaces enable adaptation to different system architectures and application requirements.
The sensor is supplied pre-calibrated and tested and is particularly suitable for heating, cooling and HVAC systems as well as household appliances and water flow measurement applications.
