Working principle of the gas meter, gas meter is developed by using the principle of the liquid vibration design, a new type of flowmeter is widely used in oil, chemical plants, metallurgical industry, paper industry and other manufacturing industries fluid metrological verification, the flowmeter can't move the component, the credibility of strong, high precision, long life, can be in wide flow range precision measuring the instantaneous velocity of the liquid flow rate and total flow rate.It will not be harmed by material temperature, working pressure, viscosity and composition, in addition, it is not blocked, smooth, not easy to scale, heat resistance, high pressure, safety explosion-proof, suitable for extreme natural environment.Flow scoring integrated display information and remote display information, and can output differential signal or current data signal connected to the microcomputer network.
How does a gas flowmeter work
The gas flowmeter is a new type of flowmeter based on "Carmen vortex" principle.
When a stationary fluid flows through a pipe of a certain length, a collision with a cylinder of a discrete system immersed in the fluid creates a vortex (i.e., a kamen vortex) in the middle and lower reaches of the fluid.
When the Reynolds number (Re) of the fluid is within a certain range, the vortex generation regularity is stable and reliable, and the vortex generation frequency F is calculated by the formula: F= (St*V) /d is clear
Where, V is the water flow;D is the total width of the inlet surface of the cylinder.
Gas flowmeter selection
First to the advantages and disadvantages of various flowmeter has the sober understanding, next to the chemical and physical properties of material have a sober understanding, again on the processing technology of the installation on the spot standards and a healthy natural environment, and finally to understand customer accurate measurement precision of flowmeter, consider to whether the material flow meter of the category of traffic regulation, installation is considering flow meter installed on the spot on the spot, also want to consider what are the conditions and elements can endanger the metrological verification of flowmeter.Summary: 1. High attention should be paid to the selection of commodity motor; 2. Good commodities should be provided; 3.
