В статье представлены результаты моделирования расходомера переменного перепада давлений с преобразователем расхода в виде расширяющего устройства, который выполняет измерение расхода потока пульсирующей жидкости. В статье описан метод получения основных модифицированных уравнений для описания моделей и представлена структура преобразователя расхода. В качестве такого расширяющего преобразователя расхода в работе используется конический диффузор. В работе получена модель такого расходомера и исследованы факторы, влияющие на процесс измерения пульсирующего расхода жидкости. Дана оценка неопределенности результатов измерения пульсирующего расхода с помощью подобного преобразователя. Исследованы факторы, влияющие на точность измерения расхода.

The article presents the results of modeling a differential pressure flowmeter with a flow transducer in the form of an expanding device that measures the flow rate of a pulsating liquid. The article describes a method for obtaining basic modified equations for describing models and presents the structure of the flow transducer. A conical diffuser is used as an expanding flow transducer in operation. In this article, a model of such a flow meter is obtained and the factors influencing the process of measuring the pulsating flow rate of a liquid are investigated. An estimation of the uncertainty of measuring results of the pulsating flow rate using such a transducer is given. The factors influencing the accuracy of flow measurement are investigated.
