V-cone Flowmeter

Principle: cone flowmeter is a kind of differential pressure flow meter, which has the same principle as other general differential pressure flow meters, and is based on Bernoulli's law of energy conversion in closed pipes. When the flow field is stable, the velocity in the pipe is proportional to the square root of the differential pressure. ...

Product introduction

Cx-vcfm V-cone Flowmeter
?
Rationale:
Cone flowmeter is a kind of differential pressure flow meter. The principle of cone flowmeter is the same as that of other general differential pressure flow meters. It is based on Bernoulli's law of energy conversion in closed pipeline. In the case of differential pressure, it is proportional to the square root of the flow field. If the upstream pressure is p
1, the downstream pressure is P2 and the differential pressure generated is △ P, then:
Δ P = P1-P2, and the β coefficient numerical equation of throttling is as follows:
β=
Where D is the inner diameter of the pipe and D is the outer diameter of the tapered throttling element
If q is the flow rate, the flow equation of differential pressure flowmeter is:
Q=ky
Among them, q is the volume flow rate, y is the gas expansion coefficient, K is the variable constant, which varies according to different components

measurement system
The differential pressure signal must be sent to the instrument to measure the differential pressure, and then the signal must be processed by the computer. For the medium with too large temperature and pressure variation or high measurement requirements, sometimes it is necessary to correct the temperature and pressure. Our company can provide these instruments, and can be programmed and calibrated before delivery.
