Improved process for the measurement of weight flowrates and related devices

摘要: The process for the measurement of weight flow-­rate an outflowing fluid inside a pipe made oscillate by impulse-generating unit at certain frequency, and constant controlled amplitude, consists in making said constantly exactly its twisting resonance counteracting oscillation with least couple brakes, performing braking action which is proportional to shifting speed, has intensity larger than Coriolis forces acting on pipe, detecting two symmetrical points relatively middle, wherein largest deformation occurs, finally determining differences amplitudes above-said shifts, difference directly desired flow-rate, but condition that all disturbances have been eliminated. Furthermore, different forms practical embodiment instruments operating according process, as well specific circuits are taken into consideration.
