Abstract

В изобретении предложены устройство и способ измерения расхода жидкости, протекающей через трубопровод. Это устройство основано на расходомере, который приспособлен для точного измерения объемного расхода жидкости с использованием простого, рентабельного, энергосберегающего и точного способа с использованием только лишь одного датчика температуры. Способ основан на введении импульса тепловой энергии в протекающую жидкость и на измерении роста температуры в зависимости от времени и подводимой мощности. Расход может быть определен путем сравнения результатов этих измерений с градуировочной таблицей, созданной путем выполнения аналогичных измерений для известных значений расхода. Одним из вариантов применения, который описан для иллюстрации признаков способа и устройства настоящего изобретения, является измерение расхода мочи, выделенной пациентом с введенным катетером.
