Create more energy efficient home heat pumps, boilers and air conditioners with our new Ultrasonic Flow Sensor. It’s no ordinary ultrasonic flowmeter—ours is engineered for more accurate flow measurement and arrives calibrated and tested to your exact specifications.
Our Ultrasonic Flow Sensor excels at touchless detection of liquid flow—including glycol concentration—even when bubbles or particulates are present. Its flexible design includes the option for software-specific capabilities. Integrated temperature measurement adds even more brainpower, enabling precise control of heating and cooling systems.
Automatic digital detection instantly identifies flow direction, bubbles/ particles, empty pipes and glycol.
Optimized to the medium,
avoiding impeller or vortex
turbulence issues
Pre-calibrated and tested to your exact specifications for optimal accuracy
Advanced components
that work together to
elevate efficiency
How does an ultrasonic flow sensor work?
An ultrasonic flow sensor (or flowmeter) uses piezo elements to send and receive a high frequency signal across the flow. Flow rate affects the transmitted signal, resulting in a delay. That difference in time—called “time of flight”—is used to calculate flow rate.
Can ultrasonic flow sensors be used for liquids with suspended solids?
In general, ultrasonic flow sensors are less impaired than other technologies by the presence of particles or solids, but performance may vary depending on size or concentration. Marquardt’s Ultrasonic Flow Sensor can be precisely calibrated to mitigate some of these performance issues.
What is the maintenance required for ultrasonic flow sensors?
Because ultrasonic flow sensors have no moving parts, no maintenance is required, and wear is minimal.
What is the maximum and minimum flow rate that can be measured by the Marquardt Ultrasonic Flow Sensors?
Depending on the application, the maximum and minimum flow rate will vary. For more detailed information, please refer to the Ultrasonic Flow Sensor data sheets.
