： Structural characteristics of V-cone flowmeter :
1 ） 自整流特性 ( 1 ) Self-rectifying characteristics
The pointed cone is in the center of the pipe, forcing the fluid to gradually shrink toward the pipe wall. The flow field is rectified by the cone. The calibration data can be reproduced without full development. The special advantage is that other flowmeters cannot do it, and it has revolutionary significance in practical applications.
量程更宽 (2) Wide range
15 ∶ 1 。 Because of the special structure of the cone, the negative pressure area generates small noise with high frequency and low amplitude, and the interference of negative pressure taking from the orifice plate is very small. Therefore, a smaller differential pressure signal can be measured, so that the range ratio can Reached 15 : 1 .
3 ）自清洗特性 ( 3 ) Self-cleaning characteristics
Dirty impurities are accelerated along the cone, so the surface of the cone cannot be retained. The gas in the liquid or the liquid in the gas as well as particles and fibers are also swept downstream through the gap between the cone and the pipe. Dirt, impurities, and blockages affect measurement to ensure long-term stable operation of the meter.
4 ）自保护 ( 4 ) Self-protection
Because of the surface layer effect formed by the fluid on the cone surface, the cone surface is protected, and abrasion will not change the key dimensions of the cone, ensuring long-term stability of measurement accuracy.
