Working principle <br /> Conical flowmeter is a differential pressure type flow meter. Flow meters designed based on the differential pressure principle have been used for more than 100 years. Differential pressure flow meters are based on the principle of energy conversion in sealed pipelines, which means that for stable fluids, pipeline pressure and the flow rate of the medium in the pipeline The square root of is inversely proportional: the pressure will decrease when the velocity increases. When the medium approaches the cone, its pressure will be P1. When the medium passes through the throttle region of the cone, the velocity will increase and the pressure will decrease to P2. Both 1 and P2 are led to the differential pressure transmitter through the pressure tap of the cone flow meter. When the flow rate changes, the differential pressure between the two pressure taps of the cone meter will increase or decrease. . When the flow velocity is the same, if the throttle area is large, the differential pressure value is also large. The β value is equal to the throttle area of the cone divided by the cross-sectional area of the inner diameter of the pipe (convertible to the diameter ratio between the two).
