FIELD: machine building.
SUBSTANCE: in a method proposed for detection of working fluid flow along a supply manifold, the inlet and the outlet of the supply manifold are communicated with tight reservoirs filled with gas, and measurement of static pressure at the inlet and outlet of the supply manifold section during its calibration and further detection of working fluid flow are carried out in tight reservoirs after their partial filling with a working fluid. As the working fluid flows, its temperature is measured, and the working fluid flow is determined by a calibration characteristic corresponding to the measured temperature. Overload that affects the supply manifold is measured, its projection at a straight line stretching via the inlet and outlet of the supply manifold section is detected. Hydrostatic pressure of working fluid column is calculated on the section of the supply manifold from the overload projection, and depending on its direction towards the inlet or outlet of the supply manifold section, it is subtracted from the appropriate measured static pressure, and static pressure difference is detected with account of the completed correction.
EFFECT: reduced error for detection of working liquid flow along a supply manifold under high speeds of flow with static pressure pulsations.
