Ultrasonic flow measurement
Fields of application
Air conditioning systems (heating and cooling water flow measurement), HVAC systems, energy-saving applications, etc.
Benefits
This fixed-mount ultrasonic flowmeter applies a measurement method based on transit time difference. By taking advantage of the latest electronic advances and digital signal processing technology, we have developed a compact, lightweight device with enhanced accuracy and ease of use, while retaining excellent immunity to air bubble formation. Communication capability (MODBUS® : optional) is also available.
