Concept and characteristics of V-cone flowmeter
2011-12-22 10:26:02

,又名;V型锥流量计;V形锥流量计;锥型流量计;锥形流量计;内锥流量计; V-cone flowmeter , also known as; V-cone flowmeter; V-cone flowmeter; cone-shaped flowmeter; conical flowmeter; inner cone flowmeter;

Practical use proves that compared with other flow meters, V-cone flowmeters have high long-term accuracy, good stability, limited installation conditions, wear resistance, wide measurement range, small pressure loss,

Suitable for dirty media and other advantages. It uses the throttling effect produced by the V-cone in the flow field to measure the flow rate by detecting the upstream and downstream pressure difference. Compared with ordinary throttles, it changes the throttle layout,

Throttling from the center hole to annular throttling. And the V-cone itself, as a rectifier of the flow field, has become an excellent new type of flowmeter with unique performance. Combination of V cone sensor and differential pressure transmitter

,可精确测量宽雷诺数(8×103≤Re≤5×107)范围内各种介质的流量 The V-cone flowmeter can accurately measure the flow of various media within a wide Reynolds number (8 × 103≤Re≤5 × 107)


V cone flowmeter features :


Use medium gas, steam, liquid, solid dust; suitable for almost all media


High accuracy: readings> 0.5%


1. Measurable gas-liquid two-phase medium (moisture, condensate, etc.)


2. Non-clogging and non-adhesion: The cone-shaped thorough purging design avoids the retention of residues, condensates or particles in the fluid

3. Wide range ratio: usually 10: 1, choosing the right parameter can achieve up to 50: 1

4. Good repeatability and stable signal: 0.1% better than the orifice plate


5. Measurable dirty media (coke oven gas, blast furnace gas, raw oil, residue oil, etc.)

6, complete specifications, flexible installation methods: optional pipe type, flange pressure type, wafer type, long-distance pipeline type


7, long-term stability is good: β rate can be unchanged for a long time, and ensure long-term accurate measurement


8. Wide pipeline range: pipeline size from 1/2

9. Measurable high temperature and high pressure medium: working temperature up to 700 ℃, maximum pressure 42Mpa


10, small pressure loss: the same β value, pressure loss is the orifice plate 1/3 ~ 1/5 low installation requirements: center V-throttle,

11. Signal stability: "Signal fluctuation" is 1/10 of the orifice plate;

12. Abrasion resistance: After the streamlined cone is throttled, a linear boundary layer effect is generated on the surface of the cone, making the cone difficult to wear, without regular cleaning and replacement of parts, and without repeated calibration


13. Wide β value range: V-cone's unique geometry allows a wide range of β values
