1.6 Rosemount 3814 Liquid Ultrasonic Flow
meter design
The Rosemount 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. Computer simulations of various velocity profiles demonstrate that
multiple measurement paths provide an optimum solution for measuring
asymmetric flow. The Rosemount 3814 Liquid Ultrasonic Flow Meter utilizes four
cross-bore, parallel-plane measurement paths, offers a high degree of
repeatability, bi-directional measurement and superior low-flow capabilities
without the compromises associated with conventional technologies.
