In the current industry, the flow rate is guaranteed to be highly efficient and safe. A variety of conventional flow metering equipment, used for petroleum, chemical industry, electricity, food, manufacturing, etc. How do you choose the main text for the main text? Choose the correct choice for the flow rate system development analysis, the key factors in the process, the comprehensive fluid characteristics, the flow rate, the power and temperature requirements, etc.
Hyakugai flow calculation principle
Water meter flow meter usage card gate meter street principle runs flow meter. When measuring the flow rate of a fluid flow system, the flow rate of the fluid flow in the pipeline is increased, and the ratio of the flow rate to the flow rate of the fluid flow is determined. The flow rate is calculated based on the calculated flow rate. In this case, the flow rate device has high precision, robustness, safety, and other advantages, making it a medium-choice design for industrial enterprises.
The key factor in selecting the city flow rate
Fluid type physical properties
Fluid measurement such as water body, liquid steam, etc. for measuring flow rate. Fluid density, viscosity, temperature control and other factors determine the selection of urban flow rates. For example, high viscosity fluid or physical selection demand special attention flow measurement design, avoidance factor flow characteristics unbalanced guide measurement difference.
Flow range and pipe size
When selecting a vortex flowmeter, it must be determined according to the flow range of the actual application. The flowmeter range should cover the change between small and large flows. The caliber of the vortex flowmeter and the pipe size should match to ensure the stability of the vortex signal and the accuracy of the measurement.
Pressure and temperature conditions
Different operating environments have a direct impact on the selection of vortex flowmeters. Vortex flowmeters are more stable and have a wider range of adaptability under high pressure or high temperature environments. Therefore, in applications under high pressure or extreme temperatures, vortex flowmeters suitable for high temperature and high pressure conditions should be selected.
Medium flow rate and flow state
The vortex flowmeter has strict requirements on the fluid flow rate. Generally, the optimal working flow rate range of the vortex flowmeter is between 2 and 12 m/s. At low flow rates, the vortex signal is weak, which may lead to unstable readings; high flow rates may cause signal overload. Therefore, the flow rate range needs to be comprehensively considered when selecting to ensure that the flowmeter operates under optimal working conditions.
Installation and maintenance of vortex flowmeter
The installation location of the vortex flowmeter should be selected in an area with stable flow, no bubbles, and no impurities to avoid the generation of interference signals. During the installation process, ensure that the straight section length of the pipeline meets the requirements so that the fluid can maintain uniform flow when passing through the flowmeter. Regular maintenance and calibration are also key to ensure the long-term stable operation of the vortex flowmeter. Since the vortex flowmeter does not rely on moving parts, its maintenance requirements are relatively low, but its performance still needs to be checked regularly to ensure measurement accuracy.
