Daniel 3418 Eight-Path Gas Ultrasonic Flow Meter
The new Daniel 3418 8-path ultrasonic flow meter crafted, developed, and designed by Emerson, offers the highest accuracy and best in class performance coupled with the same high functionality required by sophisticated fiscal measurement users.
The 3418 combines the power of two interlocked 4-path British Gas design meters in one flow meter body. The second set of chords is the mirror image of the first, which allows the meter to cancel out the effects of swirl and cross flow. The 3418 Flow Meter boasts a 0.5 OIML accuracy class and requires only five diameters of straight run and no flow conditioner.
