Ultrasonic Open Channel Flowmeter
product details

Product principle


GFM ultrasonic open channel flowmeter uses the time difference between ultrasonic emission wave and reflected wave to measure the water level in the standardized metering weir (groove), and converts it into the flow rate by using the ISO flow standard calculation method through the transmitter.
