V cone flow sensor and flowmeter The device is widely used in petroleum, chemical, natural gas, mining, metallurgy, steel, electric power, water conservancy, water supply and drainage, paper, sugar, pharmaceutical, beverage, textile, printing and dyeing, chemical fiber, environmental protection and municipal engineering, etc. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the characteristics of the V-cone flowmeter and the details of the installation method. V cone flow sensor and flowmeter The device is widely used in petroleum, chemical, natural gas, mining, metallurgy, steel, electric power, water conservancy, water supply and drainage, paper, sugar, pharmaceutical, beverage, textile, printing and dyeing, chemical fiber, environmental protection and municipal Metrology and measurement in engineering and other fields. Especially in the measurement of organic gases such as coke oven gas, blast furnace gas, natural gas, flue gas, liquefied petroleum gas, and high-viscosity and polluted media such as raw material oil and slurry, V-cone flow sensors and flowmeters have unique advantages. The working principle of 1 V cone flow sensor and flow meter The theoretical basis of 1.1 V cone flow sensor and flow meter. The V-cone flowmeter is a differential pressure flowmeter. Its theory is based on the Bernoulli's law of mutual conversion of energy in a closed pipeline, that is, in the case of a stable flow, the flow velocity in the pipeline is proportional to the square root of the differential pressure. . Structural features of 1.2 V cone flow sensor and flowmeter. Although the V-cone flow sensor and flowmeter are also differential pressure flowmeters, they break through many of the limitations of traditional differential pressure flowmeters and utilize throttling components that are coaxially installed in the pipeline. The difference is that the minimum flow section of the common shut-off device is circular, while the minimum flow section of the V-cone flow sensor and the flowmeter is annular. When the fluid flows through the gap formed by the V-cone suspended in the pipe and the pipe wall, the fluid velocity accelerates and reaches the maximum at the largest end of the V-cone, forming a low-pressure end at the downstream of the V-cone. Differential pressure, through the measurement of differential pressure to measure the flow. Due to the unique structure of the V-cone flow sensor and the throttling part of the flowmeter, the fluid does not shrink rapidly in the pipeline, the change of the fluid pressure is relatively smooth, and the differential pressure signal is more stable. Therefore, the V-cone flow sensor and flowmeter can ensure the accurate measurement of flow, especially small flow. At the same time, due to the characteristics of the suspension axis and the V-cone structure, when the fluid approaches the V-cone, the flow velocity in the center of the pipe becomes slower, and the fluid velocity near the pipe wall gradually increases, and the automatically formed high-speed fluid directly scours the inner cone throttle. and the inner wall of the pipeline, so as to automatically complete the cleaning work and avoid the adhesion and stacking of dirty media. Therefore, V-cone flow sensors and flowmeters are very suitable for fluid measurement of media containing gas in liquid, water in gas, and liquid or gas containing fixed particles or other impurities. The performance and characteristics of 2 V cone flow sensor and flowmeter 2.1 V cone flow sensor and flowmeter produce more stable differential pressure signal and more accurate small flow measurement. The pressure difference of the orifice plate is through the throttling part with the opening in the middle, so that the fluid suddenly shrinks and the flow changes, thus generating the pressure difference; The flow changes smoothly, which weakens the amplitude of the pressure fluctuation, makes the pressure difference signal generated by it more stable, and the distinguishable pressure difference signal is smaller, which is more conducive to the measurement of small flow. 2.2 V cone flow sensors and flow meters measure a wider flow range. Due to the unique structure of the V-cone flow sensor and the flowmeter, a sufficiently resolved differential pressure can still be generated at low flow rates, so that the lower limit of the differential pressure range is lower than that of the traditional differential pressure instrument, and the lower limit of the range can be extended to 15:1. 2.3 V-cone flow sensor and flowmeter have high repeatability and high measurement accuracy. V-cone flow sensor and flowmeter have better repeatability than±0.1%; measurement accuracy is better than±0.5%. Compared with traditional instruments, 2.4 V cone flow sensors and flow meters have the characteristics of wear resistance, self-cleaning, good long-term stability and long service life. The V-cone flow sensor and the V-shaped cone in the flowmeter will form a boundary layer on the surface of the V-shaped cone when the fluid flows. The fluid leaves, reducing the possibility of being worn; at the same time, its own purple plot feature makes the throttling size stable for a long time, so it has long-term stability. 2.5 V cone flow sensor and flowmeter with short straight pipe section requirements.
