Installation of gas flow meter

Abstract: The use and installation information of the gas flow meter is provided by the excellent flow meter and flow meter production and quotation manufacturers. The use and installation of the gas flowmeter: 1. When the working conditions of the flowmeter are changed (such as changing the medium, the ambient temperature changes greatly, etc.), the zero position of the instrument should be re-adjusted. At the same time, the conduit of the meter must be level. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the use and installation of gas flowmeters. Use and installation of gas flowmeter Installation of gas flowmeter: 1. When the working conditions of the flowmeter change (such as changing the medium, large changes in ambient temperature, etc.), the zero position of the instrument should be re-adjusted. At the same time, the conduit of the instrument must be installed horizontally and calibrated with a spirit level. Otherwise, it will increase the influence of working condition changes on zero drift. The rack should not be vibrated or swayed, so it is not suitable for use on ships. 2. Although the specific heat of the real gas varies with the pressure, and even some gases vary greatly, the measurement accuracy of the instrument can still be maintained within a certain range. 3. In the selection of conduit materials, in addition to considering corrosion resistance, it is better to choose materials with better thermal conductivity. Taking the measurement of nitrogen as an example, also at 0—100kg/cm2 pressure and 0 to 7 standard liters/hour flow rate, the measurement accuracy of nickel tube is 2 to 2.5% and that of stainless steel is 3 to 4% (the thermal conductivity of nickel is about three times that of stainless steel. ). 4. Since the gas flowmeter can work normally only when the specific heat of the gas is relatively stable, the specific heat value is very unstable in the case of unstable gas composition, fog in the center of the gas, and working conditions approaching the liquefaction critical area of ​​the gas. , should not use this instrument. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'The use and installation of gas flow meter'
