Abstract

В настоящем изобретении предложены расходомеры, которые способны точно измерять объемный расход жидкости, протекающей через трубопровод, не требуя априорных сведений о физико-химических характеристиках жидкости, например, для калибровки массового расхода тепла. Одной из областей применения расходомеров из настоящего изобретения является включение их в состав системы для измерения расхода мочи, выделяемой пациентом, которому введен катетер. В изобретении также предложены способы использования этих расходомеров.
