Abstract

FIELD: measurement technology. SUBSTANCE: proposed design of transducer of flow rate of liquid and gas makes it possible to increase accuracy and reliability of measurements under vibration and fouling of medium flow. This leads to possibility of its usage under severe industrial conditions. Transducer converts value of flow rate of medium to electric signal which considerably promotes task of automation of accounting process of flow rate of medium with the help of computer. Case isolates sensitive element of transducer from flow of medium which totally excludes interference from fouling and enhanced service life and reliability of transducer. Membranes of which one is central form differential vessel which changes depending on flow velocity and correspondingly on flow rate of medium. Connecting capacitance - voltage to transducer one may generate electric signal proportional to value of flow rate of medium and processing signal by traditional methods one may automate accounting process with the use of computer. If static pressure in pipe-line is high it is possible to strengthen its shell with stiffening ribs and braces. By change of shape of surface, thickness and width of membranes one may change characteristics of transducer (for instance, linear, quadrature, etc) sensitivity, initial static capacitance. One of advantages of transducer is that it does not consume any energy. EFFECT: increased accuracy and reliability of transducer.

Предлагаемое устройство датчика расхода жидкости и газа (в дальнейшем - датчик) позволяет повысить точность и надежность измерений при вибрации и загрязнении потока среды. Это обеспечивает его применение в жестких производственных условиях. Датчик позволяет преобразовать величину расхода среды в электрический сигнал, что значительно облегчает задачу автоматизации процесса учета расхода среды с помощью ЭВМ. Корпус изолирует чувствительный элемент датчика от потока среды, что полностью исключает помехи от загрязнений и повышает долговечность и надежность датчика. Мембраны, одна из которых центральная, образуют дифференциальную емкость, которая меняется в зависимости от скорости потока и соответственно расхода среды. Подключая к датчику (например, к преобразователю) емкость - напряжение, можно получить электрический сигнал, пропорциональный величине расхода среды, и дальше, обрабатывая сигнал традиционными методами, автоматизировать процесс учета с помощью ЭВМ. Если статическое давление в трубопроводе высоко, то можно укрепить корпус ребрами жесткости и распорками. Меняя форму поверхности, толщину и ширину мембран, можно менять его характеристики (например, линейную, квадратичную, и т. д.), чувствительность, начальную статическую емкость. Одно из преимуществ датчика заключается в том, что он является энергонепотребляющим.The proposed device of the sensor for the flow of liquid and gas (hereinafter referred to as the sensor) allows to increase the accuracy and reliability of measurements during vibration and pollution of the medium flow. This ensures its use in harsh industrial conditions. The sensor allows you to convert the flow rate of the medium into an electrical signal, which greatly simplifies the task of automating the process of accounting for the flow of the medium using a computer. The housing isolates the sensor element of the sensor from the medium flow, which completely eliminates interference from pollution and increases the durability and reliability of the sensor. The membranes, one of which is central, form a differential capacity, which varies depending on the flow rate and, accordingly, the flow rate of the medium. By connecting a capacitance - voltage to a sensor (for example, a converter), you can get an electrical signal proportional to the flow rate of the medium, and then, processing the signal by traditional methods, automate the accounting process using a computer. If the static pressure in the pipeline is high, then you can strengthen the body with stiffeners and spacers. By changing the shape of the surface, the thickness and width of the membranes, it is possible to change its characteristics (for example, linear, quadratic, etc.), sensitivity, initial static capacity. One of the advantages of the sensor is that it is energy efficient.
