The Daniel 3814 Liquid Ultrasonic Flow Meter is a four-path (eight transducers) in-line
meter designed to measure the difference in signal transit time with and against the flow
across one or more measurement path(s). A signal transmitted in the flow direction travels
faster than one transmitted against the flow direction. Each measurement path is defined
by a transducer pair in which each transducer alternately acts as transmitter and receiver.
The meter uses transit time measurements and transducer location information to
calculate the mean velocity.
