FUJI Ultrasonic Flowmeter Series

FUJI Ultrasonic Flowmeter Series Ultrasonic wave pulses are made to propagate diagonally from the upstream side and the downstream side with the sensor installed on the exterior of piping. Time difference caused by the flow is detected and used for the measurement of the flow rate. Ultrasonic pulses are transmitted into the liquid. Flow velocity distribution is calculated to find the flow rate, taking advantage of the nature of Doppler frequency of the echo from reflectors such as air bubbles and particles in fluid that fluctuates according to flow velocity. - Duosonics = ( FSH, FSW) - TIME DELTA-C= ( FSV, FLS, FSG, FSD) - M-Flow PW= ( FLR, FLS) - Portaflow C ( FSC, FSD) FEATUREs: Increased range of applicable fluids achieved by automatic switching High accuracy ( 0.5-1% ) achieved by pulse Doppler method adopted for the first time in the world Flow velocity distribution in piping viewed in real time High-speed response: 0.2 seconds ( Depends on piping conditions.) Relaxation of linear pipe length conditions allowed Significant improvement of resistance to air bubbles.
