FIELD: the invention refers to control-diagnostics technique of bolting-adjusting fittings of the main gas pipeline.
SUBSTANCE: the mode of definition of volumetric consumption of transported gas through closed bolting-adjusting fittings being in impulse injection of portion of indicated gas into the flow of the transported gas at the output into the bolting-adjusting fittings, registration of the moment of its appearance with the aid of sensors of concentration of indicated gas before and after the bolting-adjusting fittings and measurement of time τ of delay of marker of passing of the portion of the indicated gas from the place of its injection to the place of reception of various values of static pressure of the transported gas, at testing of the bolting-adjusting fittings in natural conditions they additionally measure duration of impulses received with the aid of the sensors of concentration at the input and output of the bolting-adjusting fittings for various static pressures they calculate the value of special broadening Δd=f(τ) of various values of static pressures of transported gas and knowing the time of delay of marker τ and its special transported broadening Δd they define volumetric consumption of transported gas through closed bolting-adjusting fittings.
EFFECT: increases accuracy of definition of volumetric consumption through bolting-adjusting fittings.
