The handling of pointer shaking of metal tube float flowmeter needs to determine the cause based on the degree of shaking and take targeted measures, as follows: Minor pointer shaking is mainly caused by medium fluctuations, such as small and frequent changes in the flow rate and pressure of liquids or gases in pipelines. Solution: Overcome by increasing damping. The damping device can reduce the influence of medium fluctuations on the float, making the pointer movement smoother. For example, installing dampers inside or outside the flowmeter, or adjusting the parameters of the existing damping structure (such as damping hole size, damping liquid viscosity in megahertz, etc.). Reason for moderate pointer shaking: Abnormal flow state of the medium, such as unstable operating pressure of gas medium, causing force fluctuations on the float. Liquid media may generate eddies or turbulence due to improper pipeline layout, such as excessive bends or improper valve opening. Solution: Gas medium: Install pressure stabilizing devices (such as pressure reducing valves, pressure stabilizing tanks) or flow stabilizing devices (such as gas rectifiers) to ensure stable operating pressure; If pressure fluctuations still exist, the air damping of the float flowmeter can be increased (such as adjusting the air damping hole or adding air damping elements). Liquid medium: Optimize pipeline layout, reduce the number of elbows and valves, or adjust valve opening to reduce flow resistance; If necessary, install a rectifier in front of the flowmeter to make the flow of the medium smoother. Reason for severe pointer shaking: Strong pulsation of the medium, such as periodic pressure fluct

uations caused by reciprocating compressors, pumps, and other equipment. Unstable air pressure or significant differences between the gas operating parameters (pressure, temperature, flow rate) provided by the user and the actual operating conditions of the flow meter, resulting in the float exceeding the orange range (such as actual flow rate far exceeding the rated flow rate of the flow meter). Solution: Medium pulsation: Install a pulsation buffer (such as an airbag buffer tank) in front of the flowmeter to absorb pressure fluctuations; Or modify the equipment that generates pulsation (such as adding variable frequency control, optimizing piston motion frequency). Parameter mismatch: Verify the operational status parameters provided by the user against the actual operating conditions of the flowmeter, and reselect or adjust the flowmeter range; If the actual flow rate is too large, a larger specification flowmeter needs to be replaced; If there is a significant deviation in pressure and temperature, it is necessary to install pressure and temperature compensation devices or correct the measurement results. Adjustment of air damping: If unstable air pressure is the main cause, further air damping can be added (such as replacing larger damping holes or increasing the number of damping components), but attention should be paid to avoiding excessive damping that may cause slow response. Other precautions: If the pointer shakes accompanied by abnormal noise or the float is stuck, it is necessary to check whether there are impurities or wear on the float inside the flowmeter. If necessary, clean or replace the components. During installation, it is necessary to ensure that the flowmeter is vertical (horizontal installation
