The V-cone flowmeter has the same principle as other differential pressure flowmeters and is also a type of throttling differential pressure flowmeter. The appearance of tower-shaped (V-shaped cone) breaks the structural pattern that has been followed for nearly a hundred years, making the throttling differential pressure instrument produce a "mass leap." A major breakthrough in V-cone flowmeters is the “change in fluid centering at the center of the pipe to shrinkage of the side wallâ€.
The boundary layer effect formed by the special structure of the flow meter makes the critical parts of the throttle not wear out, so it can keep the geometric dimension unchanged for a long time, so it can work stably for a long time without calibration.
When measuring the flow of coke oven gas, since the coke oven gas contains benzene, ammonia water and tar, these gases may be separated from the gas during the measurement and aggregate and assemble on the inner wall of the pipe and other components in the pipe. Pressure plugs in venturi tubes and orifice plates are blocked and cannot be measured. In severe cases, the flowmeters are also damaged.
The V-cone flowmeter itself is a very unique V-shaped element that interacts with the fluid in the cone. It not only creates a very good velocity distribution, but also creates a pressure zone upstream that prevents the formation and deposition of contaminants and thus maintains A constant beta value, because the high pressure measurement hole is also located in this pressure measurement section, it can also be kept clean from contamination or clogging, since the cone body can generate a controlled flocculation area around itself and downstream of it. In this flocculation area, natural energy is always kept clean without contaminant buildup, so that the low-pressure measuring hole is always kept clean. There will be no blockage.
The self-cleaning function of the V-cone flowmeter is suitable for measuring the flow of various media containing impurities, completely avoiding the clogging due to various impurities on the flowmeter and affecting the measurement work of the flowmeter. The V-cone flowmeter is the best choice for preventing clogging when the measured gas contains more debris and is prone to condense and clog.
v Cone flowmeter is purely mechanical, so it is resistant to high temperatures, high pressure, corrosion and vibration. Wide range of measurable fluids (liquid, gas, steam), wide measuring range (small flow ~ large flow), applicable pipe diameter DN15 ~ DN3000.
