FIELD: instrumentation.
SUBSTANCE: proposed plant for testing of flow meters-gas counters comprises a pipeline, stop valves, a compressor, an elastic reservoir, an inlet testing manifold, a testing header, test areas, an outlet testing manifold, a filter, a temperature sensor, an absolute pressure sensor and a differential pressure sensor, besides, a flow setting device is made in the form of two tightly adjacent polished coaxial discs rotating relative to each other with holes, at the same time in one of the discs the holes are calibrated.
EFFECT: elimination of limitation of accuracy for a plant of testing of flow meters-gas counters by accuracy of a reference flow meter, provision of a more manufacturable flow setting device.
