ABSTRACT:
A measuring method and device are provided for determining at least one pumping characteristic, or a parameter, of a fluid having at least a liquid phase and a multi-phase gas phase, with the parameter being the parameter called GLR which corresponds to the ratio of the volume of the gas phase to the volume of the liquid phase. The device comprises a positive-displacement pump, having a suction pressure, a delivery pressure and a chamber having a volume, as well as one of at least one of a pressure sensor in the chamber, a detector adapted for measuring pump work, and a sensor for knowing a volume of the chamber. The sensors and detectors each deliver a value, and the characteristic to be determined is a characteristic which is not measured by the device.
