v Cone flowmeters are installed in long, flat tubes. If there are no obstructions and no disturbances, the fluid is called full development flow. If you take a line on the diameter of the pipe, the flow rate at each point on the line is different. The fluid at the pipe wall is almost zero due to the frictional force, and the flow rate at the center is the highest. If a cone is suspended in the center of the pipe, it forces the flow rate at the center to slow down and the flow rate near the pipe wall is accelerated, thereby achieving the effect of "homogenizing" the flow rate. The center of other differential pressure flowmeters is empty and cannot homogenize the flow rate. This is one of the great advantages of the V-cone flowmeter, which allows the V-cone to generate enough differential pressure at low flow rates. This effect is even more pronounced with decreasing flow rates, and it also reduces the need for straight pipe sections. Claim. In this state, other traditional differential pressure meters may not be able to measure.
1. A very mature and well-known technology = ease of use and ease of use;
2. No internal electronic components = flexible to use (change range, replacement, maintenance, on-site inspection); not affected by electromagnetic interference in the field;
3. The user retains the right and opportunity for the selection of the electronic part; the electronic part (transmitter) can be individually calibrated and easily integrated;
4. No moving parts, high repeatability;
5. Applicable area width, flexible use case (Applicable medium: liquid/gas/steam; high/medium/low temperature, high/medium/low pressure; high/medium/low flow rate; clean/dirty fluid; large/medium/small tube path)
6. The highest degree of standardization;
7. Accuracy is guaranteed: the error caused by the change of density is small, only 1/2 of speed-type flowmeter (such as electromagnetic, vortex, turbine, ultrasonic flowmeter); (∵ density item is within the root number)
8. Very flexible permanent pressure loss / drop; (flexible in design, β value can be selected as needed);
9. Replaceability and expandable ability; (differential pressure transmitter, the second table, a component can be replaced, differential pressure transmitter can be connected in parallel to expand the range)
10. Easy verification (as long as the hydrodynamics are similar and geometrically similar, the outflow coefficient can be replicated);
11. There are many types of primary components for a variety of materials to choose from, especially the new generation of AVZ;
12. Can install insulation (heat tracing) device to achieve liquid viscosity reduction;
13. According to the use of environmental requirements, classification and classification, easy to meet the explosion-proof requirements.
14, with good accuracy (≤ 0.5%) and repeatability (≤ 0.1%).
15, with a wide range ratio (10:1 ~ 15:1)
16, since the rectifier function, only a very short straight pipe (1 ~ 3D before 0 ~ 1D).
17, self-cleaning function, can measure dirt and easy fouling fluid, suitable for blast furnace gas and other impurities more media.
18, self-protection function, the critical parts of the throttle are not worn, can maintain long-term stable work.
19, high temperature, high pressure, corrosion resistance, not afraid of vibration.
20, the type of measurable fluid is very wide (liquid, gas, steam), flow measurement range is wide (minor flow ~ large flow), adapt to the pipeline DN15 ~ DN3000.
21. The structure design of the flowmeter is a fluid sweep type structure. It is impossible to retain any entrapped gas, liquid or solid dirt in the fluid. It is very suitable for measuring the flow of dirty fluids, such as coke oven gas, wet gas, etc.
22, no moving parts
23. When the fluid flows through the inner cone with a special profile, a boundary layer is formed at its periphery and the fluid is removed from the edge of the cone tail, thereby reducing the possibility of it being worn out.
24. Steam and hot water are measured at the heat exchange station without the need for a straight pipe section. Due to the relatively small space of the heat exchange station, the selection of a general flowmeter requires a long straight pipe section, which affects the running accuracy. It is used to measure blast furnace gas and has a self-cleaning effect. The pressure-inducing pipe is not easy to be blocked.
