Abstract | An apparatus and a method are described for measuring the mass flow rate of material flowing through at least one vibrating conduit. A pair of motion detectors (P1, P2) is disposed at separate points along the conduit for detecting motion thereof and for developing first and second motion responsive analog voltage signals (V1, V2). Differencing means (30) are responsive to said first and second analog voltage signals (V1 and V2) and generate a difference signal (V3) which is proportional to the voltage difference therebetween. Further, summing means (32) are provided which are responsive to said first and second analog voltage signals (V1, V2) and generate a sum signal (V4) which is proportional to the sum of the voltages thereof. Integrating means (34) are provided for integrating said difference signal (V3) and, further, dividing means (36) are used for dividing the integrated difference signal (V5) by said sum signal (V4) to develop an output signal (V6) proportional to the mass flow rate of material flowing through the conduit. |
