Ultrasonic Flow Meters

  • Patented temperature and glycol compensation logic accurately reads flow and eliminates calibration requirements.
  • Low power consumption of 0.5W saves energy and transformer capacity.
  • Multi-point wet calibrated to ensure accuracy and repeatability.
  • Analog output range of 0 to 10 VDC easily integrates with building automation systems.
  • Maintenance free.


Belimo ultrasonic flow meters are designed for HVAC chilled water, hot water, and water/glycol solutions from -4°F to 250°F [-20°C to 120°C] up to 60% glycol. These flow meters utilize ultrasonic transit time technology and Belimo’s patented temperature and glycol compensation logic to compensate for variations in a systems water composition to accurately indicate flow.
