Abstract
The invention is intended for determining the quantity yield of a compressible fluid flowing through a conduit which is provided with a pressure reducing valve. According to the invention, this determination is made by using a vibration sensor which is subjected to vibrations from the pressure reducing valve, and at least one pressure sensor mounted upstream of the valve. The signals emitted by the vibration sensor are processed in a processing unit. These processed signals and the signals emitted by the pressure sensor are digitalized in an analog to digital converter unit, and then sent to a computer, which, using the data previously stored in its memory unit, outputs a value corresponding to the quantity of fluid. The invention is particularly designed for use in measuring the quantity yield of a combustible gas.
