FIELD: measurement equipment.
SUBSTANCE: invention relates to the field of flow meters. More precisely, the invention describes a prover of a flow meter, a check method of a flow meter and a computer of the flow meter prover. A group of inventions is proposed, which includes a prover of a flow meter, a check method of a flow meter and a computer of the flow meter prover. With that, the flow meter prover includes a pipe having a check section, a displacer installed in the pipe with possibility of being moved along the check section between the first and the second positions, the first pair of sensors, which is installed in the check section and determines the first calibrated volume, the second pair of sensors, which is installed in the check section between the first and the second positions and determines the second calibrated volume, and a processer; with that, the first and the second pairs of sensors are installed so that they can transmit to the processor the data on the first and the second calibrated volumes at each pass of the displacer between the first and the second positions, and the processor is made so that it can create the first and the second sets of samples as per the first and the second calibrated volumes respectively. The flow meter check method involves multiple passage of the displacer through the prover, actuation of the first pair of sensors by means of the displacer; the first calibrated volume is determined by means of the above first pair of sensors at every run of the displacer; reflection of the first calibrated volume at each run of the displacer; actuation of the second pair of sensors by means of the displacer; the second calibrated volume is determined by means of the second pair of sensors at each run of the displacer; reflection of the second calibrated volume at each run of the displacer; creation of the first set of samples of the first reflected calibrated volumes and creation of the second set of samples of the second reflected calibrated volumes. The flow meter prover computer includes a processor connected to a multi-volume prover equipped with a displacer, which can receive signals, at each run of the displacer, on the first and the second calibrated volumes with the corresponding sets of pulse signals of the flow meter, which are generated at one run of the displacer, and creation of the first and the second sets of samples by means of sets of signals on the first and the second calibrated volumes respectively.
EFFECT: achieving the required repeatability and error of measurements.
