Structural features of the V-cone flowmeter

1, self-protection

Due to the boundary layer effect of the fluid on the surface of the cone, the surface of the cone is protected and the critical dimensions of the cone are not altered by wear, ensuring long-term stability of the measurement accuracy.

2, self-rectifying characteristics

Since the tip cone is at the center of the pipe, the fluid is forced to shrink toward the pipe wall, so that the flow field can be rectified through the cone. The data can be reproduced in real time without sufficient development. The requirements of the straight pipe section are very short. The advantage is that other flowmeters can't do it, and it has revolutionary significance in practical applications.

3, self-cleaning characteristics

Since the fluid is accelerated along the cone, the dirty impurities cannot retain the surface of the cone; the liquid in the liquid or the liquid in the gas, as well as the particles, fibers, etc., are swept downstream through the gap between the cone and the pipe, and there is no dirt or impurities. Surviving, clogging and affecting measurement can ensure long-term stable operation of the instrument.

4, wider range

Due to the special structure of the cone, the negative pressure region produces low frequency and low amplitude noise, and the negative pressure and pressure interference of the orifice plate is small, that is, the smaller differential pressure signal can be measured, so that the range ratio can be achieved. 15:1.
