METHOD FOR CONTROL OF OPERATION OF A GAS-MEASURING STATION

A method for control of operation of gas-measuring station includes control with period Tof serviceability of sensors that measure parameters, and additional control of temperature sensors. One measures parameters of gas flow that characterize gas flow rate. The control of serviceability of sensors is carried out at all the measuring pipelines through determination for each measuring pipeline of the average values of each of measured first and second parameters that characterize gas flow rate, during the period of control T, calculation after the end of each period of control Tof difference of average values of each of respective first and second parameters that characterize gas flow rate. If difference of average values of respective parameters for the measuring pipeline does not exceed the error of measurement of respective parameter one considers the sensors to be inoperable. If difference of values of any respective parameters exceeds the error of measurement of the parameter that is given, one considers sensors that measure those parameters to be out of order. Additional control of temperature sensors of the first and the second device for determination of gas flow rate of all operating measuring pipelines one carries out at the end of given time interval through comparison of values of temperature measured by temperature sensors of both devices for determination of gas flow rate for each measuring pipeline to temperature values measured in that very measuring pipeline with a control thermometer with class of accuracy not lower that that of temperature sensors. At coincidence, with account of accuracy of the sensor and control thermometer, of the value of temperature measured by the sensor and the value measured by control thermometer, one considers that temperature sensor is operable. At discrepancy, with account of accuracy of the sensor and control thermometer, of temperature value measured by any sensor and the value measured by control thermometer, one considers the sensor is nonserviceable. Спосіб контролю роботи газовимірювальної станції включає контроль з періодом τсправності датчиків, що вимірюють параметри, і додатковий контроль датчиків температури. Вимірюють параметри потоку газу, що характеризують витрату газу. Контроль справності датчиків здійснюють для всіх працюючих вимірювальних трубопроводів шляхом визначення для кожного вимірювального трубопроводу середніх значень кожного з вимірюваних перших і других параметрів, що характеризують в
