Claims (1)

Способ определения расхода пульсирующего потока газа на магистральном газопроводе методом переменного перепада давлений на сужающем устройстве, включающий измерение давления и температуры перед диафрагмой и перепада давления на диафрагме, вычисление подкоренного выражения указанных параметров и определение по их усредненным значениям коэффициента расхода, отличающийся тем, что предварительно определяют спектральное распределение пульсаций газового потока на газопроводе и производят измерение давления перед сужающим устройством и перепада давления на диафрагме с частотой, по крайней мере, в два раза большей максимальной частоты спектра пульсаций, находят усредненное значение подкоренного выражения упомянутых давлений и температуры, по которому с учетом коэффициента расхода определяют расход пульсирующего потока газа.A method for determining the flow rate of a pulsating gas flow in a main gas pipeline by the method of variable differential pressure on a constricting device, including measuring pressure and temperature in front of the diaphragm and differential pressure on the diaphragm, calculating the radical expression of these parameters and determining their averaged flow coefficient, characterized in that it is previously determined spectral distribution of pulsations of the gas flow in the gas pipeline and measure the pressure in front of the constricting device and a differential pressure on the diaphragm at a frequency at least twice the maximum frequency pulsation spectrum, finding the average value of the radicand of said pressure and temperature at which the given flow rate coefficient is determined pulsating gas flow.
