The use of gas meter scale installation

Abstract: the use of gas meter scale installation information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. The use of gas meter installation the use of gas meter installation: 1, when the meter working conditions transform ( Such as the change of medium, environment temperature change, etc. ) Readjust, zero to the instrument should be. At the same time, the instrument tube must be level. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the use of gas meter scale installation details. The use of gas meter installation the use of gas meter installation: 1, when the meter working conditions transform ( Such as the change of medium, environment temperature change, etc. ) Readjust, zero to the instrument should be. At the same time, the tube must be installed level, with level calibration. Otherwise will increase the working conditions change on the influence of the zero drift. Frame swing or more with no vibration, so should not be used on ships. 2, although the specific heat of real gas varies with the different of pressure change and even some gas range is relatively large, but the instrument measuring precision stays a laurel a certain range. 3, selection of pipe material, in addition to the consideration of corrosion resistance, is better to choose material with better thermal properties. Test item nitrogen, for example, in the same 0 & ndash; 100 kg/cm2 pressure and 0 ~ 7 liters/hour traffic within the scope of testing, with the measuring accuracy of nickel pipe is 2 ~ 2. 5% while stainless steel is 3 ~ 4% ( The coefficient of thermal conductivity of nickel is about three times that of stainless steel) 。 4, due to the gas meter must be under the condition of the gas specific heat is relatively stable to unstable work properly so that the gas composition, gas central belt entrainment and approximation gas liquefaction critical area of the working conditions as than calorific value was unstable, unfavorable use this instrument. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
