Any measuring instrument has an important indicator, which is accuracy. The same is true for flow meters. The higher the measurement accuracy, the better the efficiency and safety in production. Therefore, the accuracy must be considered when purchasing a flow meter. Since accuracy is considered, it needs to be considered in terms of various selection parameters.When selecting the type of rotameter and float flowmeter, temperature, pressure, measuring medium, density, flow range, material, etc. will affect the measurement error.In terms of temperature and pressure, these two parameters have a great influence on the density of gas. Gas is easily compressed, and temperature changes, pressure changes, and medium density also change. In the production process, the flow meter is calibrated according to the parameters provided by the customer when calibrating. Errors may occur when measured in different environments. The second is the flow range problem. The flow range should also be accurate. Don’t think that the flowmeter of the same caliber, the larger the flow, the better. The minimum and maximum flow rates of glass rotameter and metal tube rotameter are both 10 times. It is often more accurate that the commonly used flow rate is about 60% of the flow rate range, so this flow rate range should also be taken into consideration when selecting a model. The third one is the medium. The density of the medium itself is also different, and some mediums are corrosive. When considering the selection of the flowmeter, the material must be considered.Also need to consider its various other parameters, such as its ability to withstand pressure, these are the more important factors that affect its work.To put it simply, the purchase of a glass rotor flowmeter is not a very simple matter, and a comprehensive analysis and consideration of the problem is required, so that the correct flowmeter model can be selected and the most effective flowmeter can be obtained.
