What is ultrasonic flowmeter working principle?
There are three kinds of liquid ultrasonic flowmeter based on different working principle. They are transit-time flowmeter,Doppler ultrasonic flowmeter and cross-correlation ultrasonic flowmeter. The products we are offering are the first one— the transit-time ultrasonic flowmeter. A transit-time flowmeter is based on the time difference between upstream and downstream sound propagation intervals. It usually provides very good accuracy (1%). It works well for clean flow or flow with minor particles. Applications include pure water, sea water, wash water, sewage, process liquids, oils, chemicals, and any homogeneous liquids which are capable of ultrasonic wave propagation. The most widely used ultrasonic flowmeters are based on the transit-time principle. As shown in the figure A typical transit-time ultrasonic flow meter system utilizes two transducers that function as both ultrasonic transmitter and receiver. The flow meter operates by alternately transmitting and receiving a burst
