САМОДІАГНОСТУВАННЯ ВИТРАТОМІРА НА БАЗІ МЕТОДУ ЗМІННОГО ПЕРЕПАДУ ТИСКУ ПІД ЧАС ВИЗНАЧЕННЯ ВИТРАТИ ПРИРОДНОГО ГАЗУ

The purpose of this communication is to present a methodology for self-diagnosis of a flowmeter based on the method of variable differential pressure under operating conditions of Ukrainian gas networks, which have mostly non-stationary modes of gas flows in pipelines. The implementation of this methodology will reduce operating costs by switching to preventive maintenance of the flowmeter based on the variable differential pressure method, taking into account the risks of metrological failures.
