Transit Time Ultrasonic Flowmeter: A pair (or pairs) of transducers, each having its own transmitter and receiver, are placed on the pipe wall, one (set) on the upstream and the other (set) on the downstream. The time for acoustic waves to travel from the upstream transducer to the downstream transducer ta is shorter than the time it regires for the same waves to travel from the downstream to the upstream tu. The larger the difference, the higher the flow velocity. Flow direction tu Upstream transducer ta and tu can be expressed in the following forms: |d= 2 = td L c+V cose L c-V cose Downstream transducer Flow direction Question 2 (14 points) Listen Draw and explain, how a ultrasonic flow meter is used to measure the volume flow rate..
