Daniel 3410 series meter design

Daniel 3410 Series Gas Ultrasonic Flow Meters are designed to accurately measure
products in applications where reliable performance is critical, by measuring 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.
Daniel 3417 Gas Ultrasonic Flow Meter is a redundant 4-path meter design based on the
Daniel 3414 model. It has two 4-path British Gas meters in one body, where the second
coplanar 4-path meter mirrors the first and provides the same level of accuracy. Each
meter utilizes an independent set of four direct (cross-bore), parallel-plane measurement
paths that offer a high degree of accuracy and repeatability. Both meters offer bi-
directional measurement and superior low-flow capabilities, without the compromises
associated with conventional technologies.

Daniel 3416 Gas Ultrasonic Flow Meter is a custody meter and check meter in one body.
The primary custody meter is a 4-path British Gas meter design based on the Daniel 3414
model. The custody meter is independent and utilizes four direct (cross-bore), parallel-
plane measurement paths that offer a high degree of accuracy and repeatability. The
secondary check meter uses reflective (bounce) paths rather than direct chordal paths and
