Abstract

A device to measure the mass-flow rate of a fluid from the Coriolis force resulting from the flow of the fluid through the device during oscillation. The device comprises four U-shaped tubes wherein the phase and direction of flow in these tubes are arranged so as to cancel the errors due to motion of the instrument base.
