Why can vortex flowmeters be installed vertically under certain operating conditions? Detailed explanation of reasons

Under certain operating conditions, vortex flowmeters can be installed vertically, mainly because vertical installation can utilize fluid dynamic characteristics to ensure a full tube state, avoid gas accumulation, and meet the measurement requirements of specific media, while also meeting installation specifications. The specific reasons are as follows: Vertical installation can ensure that the measuring pipe section is full (for liquid measurement). Principle: When measuring the liquid flow rate in the measuring hall, vertical upward installation (the medium flows from bottom to top) can rely on the fluids own dynamic characteristics to keep the liquid filled in the measuring pipe section at all times. During the upward flow of liquid, the balance between gravity and fluid dynamics is achieved, avoiding the possibility of liquid not filling the pipeline section due to pipeline inclination or horizontal placement. Advantage: Full tube state is a prerequisite for accurately measuring liquid flow rate. If the measuring pipe section is not filled with liquid, it will cause unstable vortex signals and errors in the measurement of land code. Vertical installation effectively avoids this problem and improves measurement accuracy. Principle of avoiding measurement errors caused by gas accumulation: In liquid measurement, there may be a small amount of gas inside the pipeline. If installed horizontally, gas is prone to accumulate above the pipeline, forming air pockets. When installed vertically upwards, the gas flows upwards with the liquid and does not accumulate in the measuring pipe section. Advan

tage: Gas accumulation can affect the measurement accuracy of vortex flowmeters. The presence of gas can alter the density and velocity distribution of fluids, causing distortion of vortex signals. Vertical installation ensures the stability and accuracy of measurement signals by avoiding gas accumulation. Principle of ensuring uniform distribution of solids in fluid: When solid particles are present in the fluid, vertical installation can ensure even distribution of solid particles in the fluid. During the vertical upward flow process, solid particles are subjected to the combined effects of gravity, buoyancy, and fluid drag, and will not settle or concentrate in a certain area at the bottom of the pipeline. Advantage: The uniform distribution of solid particles helps maintain the stability of the flow field, enabling the vortex flowmeter to accurately detect vortex signals. If the distribution of solid particles is uneven, it will cause flow field disturbance and affect measurement accuracy. Compliance with specific installation specifications for straight pipe sections: When installing a vortex flowmeter, there must be sufficient straight pipe sections upstream and downstream to ensure the stability of fluid flow. Vertical installation also needs to meet this requirement. The length of the upstream straight pipe section is generally not less than 15-20 times the pipe diameter, and the length of the downstream straight pipe section is not less than 5-10 times the pipe diameter. Inner diameter matching of pipeline: When installing sensors, the inner diameter of the pipeline must be the same as that of the sensor. If they cannot be exactly the same, a pipeline slightly larger than the sensor diameter should be used, with
