FIELD: measuring equipment.
SUBSTANCE: device and method of monitoring of flow measuring system. In one version flow system comprises flow meter, first and second pressure sensors, flow stabiliser and device for condition monitoring. Flow meter is configured to measure volume of fluid medium flowing through flow meter. First pressure sensor is located near flow meter for measurement of fluid pressure near flow meter. Flow stabiliser is located upstream of flow meter. Second pressure sensor is located upstream of flow stabiliser for measurement of fluid pressure upstream of flow stabiliser. Device for condition monitoring is connected with flow meter and pressure sensors and is configured to establish possible deviation in operation of flow meter system based on difference between pressure measurements of first and second pressure sensors.
EFFECT: technical result is increased measurement accuracy due to use for monitoring operation of pressure sensor near flow meter and to set of possible changes in operation of flow regulator.
