Selection conditions of turbine gas flow meter in measurement

Selection conditions of turbine gas flow meter in measurement

The turbine type gas flow meter mainly uses the turbine in the gas to sense the average speed of the gas, and is used to measure the volume flow of the gas. During the measurement process, the speed of the turbine is proportional to the volume of the medium being measured. Realized the flow measurement.

    When selecting a gas flow meter, we should pay special attention to factors such as fluid, instrument characteristics, installation requirements, and environmental requirements. For the characteristics of the medium gas, we need to conduct a detailed investigation. The characteristics of the fluid mainly include the pressure of the medium. , Temperature, density and other characteristics, in the process of inspection, we must know that the volume of the gas will change with the temperature and pressure of the medium, so we can consider compensation and correction when necessary. For the performance of the meter, we should focus on its characteristics such as accuracy, repeatability, and range ratio. In the selection, we should analyze and compare according to the indicators we know. The gas flow meter also needs to be selected according to the installation conditions such as the flow direction of the medium, pipe direction, pipe diameter, and installation location. They will affect the operation, maintenance and life of the flow meter. We should also consider the installation when choosing a gas flow meter. , Maintenance, purchase, calibration and other expenses, can not be purchased blindly, otherwise it will reduce the service life and measurement accuracy of the flowmeter.

    The turbine type gas flowmeter has the characteristics of high measurement accuracy and large flowmeter. It can also achieve temperature and pressure compensation in the measurement. At that time, it required higher installation lengths of straight pipe sections, which increased the difficulty during installation. In addition, it also has higher requirements for the cleanliness of gas, so it can be used for measuring natural gas and liquefied petroleum gas, and is mostly used in furnaces of industrial and mining enterprises.
