Claims (2)

1. Способ измерения микрорасхода газа, включающий помещение теплочувствительного элемента в охлаждающий его поток газа, отличающийся исключением влияния температур входящего газа и внешней среды на показания микрорасходомера путем термостабилизации газового потока на фиксированном уровне.1. A method of measuring micro-flow of gas, comprising placing a heat-sensitive element in a gas flow cooling it, characterized in that it excludes the influence of temperatures of the incoming gas and the environment on the readings of the micro flow meter by thermal stabilization of the gas flow at a fixed level. 2. Тепловой микрорасходомер, содержащий корпус с расположенным в нем газовым трактом, отличающийся тем, что, с целью автономизации расходомера газовый тракт содержит теплообменник управляемой мощности, а улучшение качественных показателей микрорасходомера (точность, чувствительность, диапазон измерения расхода) достигается заменой металлического теплочувствительного элемента полупроводниковым термисторным и разделением газового потока дополнительно введенной газораспределительной на два идентичных по расходу и температуре газовых потока. 2. Thermal micrometer, comprising a housing with a gas path located in it, characterized in that, for the purpose of autonomy of the flow meter, the gas path contains a heat exchanger of controlled power, and the improvement of the quality of the micrometer (accuracy, sensitivity, flow measurement range) is achieved by replacing the metal heat-sensitive element with a semiconductor thermistor and separation of the gas flow of the additionally introduced gas distribution into two gases identical in consumption and temperature th flow.
