What is the approximate price of a rotor flowmeter?
2. Installation method of V-cone flowmeter
1: The installation method of pipeline flange is: the V-cone flowmeter has two flanges at each end, which are connected to the flanges on the pipeline. This is a commonly used connection method in industry, especially suitable for connecting various pipeline diameters. This installation method can be installed separately with differential pressure transmitters and is usually used to measure the flow rate of steam and high-temperature media.. 2: The flange clamping installation method is as follows: the two opening ends of the V-cone flowmeter are each equipped with flanges. When the connected pipeline has no flange connection, welding can be used for connection, and then the V-cone flowmeter is installed between the flanges. 3: The pipeline welding installation method is to directly weld the V-cone flowmeter to the pipeline without flange connection. This method has a lower installation cost and reduces the cost of four flanges. It is suitable for installation sites with large caliber flow meters and belongs to the one-time vertical installation method.
3. Technical specifications of V-cone flowmeter
▲ High precision: ± 0.075% ▲ High stability: better than 0.1% fs/year ▲ High static pressure: 40mpa ▲ Continuous operation for 5 years without calibration ▲ Negligible temperature and static pressure effects ▲ Resistance to high overpressure in all directions
1. It has good accuracy (≤ 0.5%) and repeatability (≤ 0.1%).
.2、 It has a wide range ratio (10:
3. It has self rectification function and only requires a very short straight pipe section (front 1-3D and back 0-1D).
4、 Self cleaning function, capable of detecting dirty and easily scaling fluids, suitable for media with high impurities such as blast furnace gas.
5、 Self protection function, key parts of the throttle component do not wear out, and can maintain long-term stable operation.
6、 Resistant to high temperature, high pressure, corrosion, and vibration.
7、 The types of measurable fluids are very wide (liquid, gas, steam), and the flow measurement range is wide (small flow to large flow), suitable for pipelines ranging from DN15 to DN3000.
8、 The structure design of the flowmeter is a fluid sweep type structure, which cannot intercept any gas, liquid or solid pollutants carried in the fluid. Non state flow meters are often suitable for flow measurement of dirty fluids, such as coke oven gas, wet gas, etc. 9. No movable parts 10. When the fluid flows through an inner cone with a special profile, a boundary layer will be formed around it and the fluid will be guided away from the edge of the cone tail, thereby reducing the possibility of wear. 1
1、 Measure steam and hot water at the heat exchange station without the need for a straight sail or buried pipe section. Due to the small space of the heat exchange station, selecting a general flow meter requires a long straight pipe section, which affects the operating accuracy. It is used to measure blast furnace gas and has a self-cleaning effect. The pressure pipe is not easily blocked.
