1. Precautions for the use and installation of steam flow meters

Precautions for the use and installation of steam flow meters: Maintain a constant specific pressure heat capacity: When measuring gas flow, it is necessary to ensure that the specific pressure heat capacity of the gas remains constant. Therefore, steam flow meters cannot be used to measure gases with changes in composition, as changes in composition can cause changes in specific heat capacity at constant pressure, thereby affecting measurement accuracy. Gas must be dry: During measurement, the gas should be kept dry and avoid approaching the critical point to prevent unstable states such as liquefaction phase transition. Liquefied phase transition can lead to inaccurate measurement of flow meters and may even damage them. Avoid mixing liquid with bubbles: Steam flow meters cannot be used to measure mixed phase flows or fluids that may undergo phase transitions. When measuring liquids that are prone to vaporization, attention should be paid to the influence of heating elements on the measured liquid. If necessary, flow meters with cooling elements (i.e. negative heating elements) should be selected to ensure measurement accuracy. Handling pipelines containing smoke and gas production: When steam flow meters are applied to pipelines containing smoke and gas production, a separator or filter should be installed in front of the instrument to remove these impurities and prevent them from causing damage to the flow meter or affecting measurement accuracy. Installation precautions: Installation posture of flow sensor: Different types of steam flow meters have different requirements for the installation posture of the bucket. For example, the insertion

detection heads of thermal distributed capillary flow meters and Guinness law tube segment flow meters can be installed in any position, but some flow sensors are sensitive to installation positions. Therefore, during installation, the instrument manual should be carefully read and installed according to the requirements to ensure measurement accuracy. Especially for thin tube flow sensors, they can usually only be used and calibrated in the horizontal direction. If installed vertically, it may be affected by natural convection of the environmental atmosphere, resulting in inaccurate measurements. During installation, the horizontal deviation should be controlled within the allowable range. Requirements for straight pipe sections: Different types of steam flow meters have different requirements for upstream and downstream straight pipe sections. The thermal distributed flowmeter is not affected by the distortion of the flow velocity distribution profile and the rotating flow, as it is not sensitive to the requirements of the upstream and downstream straight pipe sections. However, the Jins law of pipe section access type or insertion type flowmeter is affected by these factors and requires a certain length of upstream and downstream straight pipe sections to ensure measurement accuracy. Currently, there are no specific regulations on this in international or national standards. Therefore, in practical applications, the required length of the straight pipe section should be determined based on the specific situation and the instrument manual. In summary, when using and installing steam flow meters, the above precautions should be strictly followed to ensure the accuracy of measurement and the normal operation of the flow
