IPC: G01F1/84
Filed: 1994-08-25
Abstract: PURPOSE: To realize a highly accurate measurement regardless of the temperature variation or the like by contriving the connection method for lead wires to detect the difference and the sum of signals from a plurality of vibration detectors directly. CONSTITUTION: A sensor means 50 comprising two vibration detectors delivers a vibration speed difference signal 100 and a vibration speed sum signal 101, respectively, to amplifiers 7, 8 and the output of the amplifier 7 is connected with a synchronous rectification/integration operating means 9. With such connection of lead wires, a difference signal and a sum signal of the vibration speed of a tube are obtained from the means 50 wherein the difference signal 100 is composed of a Coriolis amplitude component and an exciting amplitude component. The difference signal 100 then undergoes synchronous rectification and integration at the means 9 using the sum signal 101 as a reference signal and outputted as a Coriolis component signal 102 from the means 9. Since the signal 102 is proportional to the mass flow rate, the mass flow rate can be determined based on the signal 102.
