Abstract

FIELD: measurement technology. SUBSTANCE: invention refers to means measuring flow rate of liquids and gases by usage of mark put into fluid medium. It may find use in chemical industry, in public services and so on. In compliance with proposed method flow of measured medium is passed through measurement section of pipe-line with uninterrupted formation of mark in the form of anomalous area at inlet to section, mark is registered at outlet of section. With emergence at outlet of signal of registration of its onset this signal is sent to input of mark former and by it formation of mark at input is stopped till moment of emergence of signal of registration of its end at outlet of section. Then mark is formed again and flow rate of medium is determined by frequency of emergence of mark. Device for implementation of proposed method has measurement section of pipe-line at which inlet former of mark is mounted, reference pickup is placed ahead of it, which output is connected to one input of comparator. Output of registration pickup is connected to second input of comparator. Registration pickup is installed at outlet of measurement section. Output of comparator is connected to input of former of mark and to input of measurement circuit composed of frequency divider and counter of number of pulses connected in series. EFFECT: simplified design measurement device. 2 cl, 2 dwg

Изобретения относятся к средствам измерения расхода жидкостей и газов с использованием метки внутри текучей среды и могут использоваться в химической промышленности, коммунальном хозяйстве и т.п. Целью заявляемых изобретений является упрощение средств измерения. Сущность изобретений: способ измерения расхода жидких и газообразных сред заключается в том, что поток измеряемой среды пропускают через измерительный участок трубопровода, непрерывно формируют на входе участка метку в виде аномальной области, регистрируют ее на выходе участка и при появлении на выходе сигнала регистрации ее начала подают этот сигнал на вход формирователя метки и по нему прекращают формирование метки на входе до момента появления сигнала регистрации ее конца на выходе участка и лишь затем формируют ее снова и определяют расход среды по частоте следования метки. Устройство для осуществления указанного способа содержит измерительный участок трубопровода, на входе которого установлен формирователь метки, а перед ним - опорный датчик, выход которого подключен к одному входу компаратора, к второму входу которого подсоединен выход датчика регистрации, установленного на выходе измерительного участка, выход компаратора подключен к входу формирователя метки и к входу схемы измерения, состоящей из последовательно соединенных делителя частоты и счетчика числа импульсов.The invention relates to means for measuring the flow of liquids and gases using a tag inside the fluid and can be used in the chemical industry, utilities, etc. The aim of the claimed invention is the simplification of measuring instruments. The inventive method for measuring the flow rate of liquid and gaseous media is that the flow of the medium to be measured is passed through the measuring section of the pipeline, a mark is continuously formed at the inlet of the section in the form of an anomalous region, it is recorded at the output of the section, and when the signal of registration of its beginning appears at the output this signal to the input of the label former and on it the formation of the label at the input is stopped until the signal of registration of its end at the output of the section appears and only then it is formed again and determined ie consumption of protection by repetition frequency tags. The device for implementing this method comprises a measuring section of the pipeline, at the input of which a label former is installed, and in front of it is a reference sensor, the output of which is connected to one input of the comparator, the output of the registration sensor installed at the output of the measuring section is connected to its second input, the output of the comparator to the input of the label driver and to the input of the measurement circuit, consisting of a series-connected frequency divider and a counter of the number of pulses.
