Ultrasonic flow meter is designed to measure the fluid velocity of liquid within a closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and easy installation.
Transit-time flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers can be mounted in V-method where the sound transverses the pipe twice, or W-method where the sound transverses the pipe four times, or in Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. This selection of the mounting method depends on pipe and liquid characteristics. The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers.
The pipe type ultrasonic flowmeter consists of the main unit and a pipe type sensor. The DN15-DN32 uses a π Type Pipe Transducer, and the DN40 and above uses a standard pipe-type sensor. The pipe type ultrasonic flowmeter has the advantages of simple installation, high measurement accuracy, and no pressure loss. Widely used in tap water, heating, water conservancy, metallurgy, chemical, energy and other industries
