Overview of integrated V-cone flowmeter:

Integrated V-cone flowmeterIt is a throttling device that integrates the classic Venturi tube and annular orifice plate. Its theoretical principle is based on the Bernoulli equation of energy conservation and the flow continuity equation in a closed pipeline, and is used in stable flow

The flow velocity in the pipeline is proportional to the square root of the differential pressure. The V-cone flowmeter has low requirements for the installation of pipeline sections and low pressure loss, and can measure fluids containing particles, low-pressure fluids, high humidity gases, and various dirt and stains

Fluid utilizes the throttling effect generated by the V-cone in the flow field to measure flow rate by detecting the upstream and downstream pressure difference. Compared with ordinary throttling components, it has changed the throttling layout from a central orifice throttling to a circular one

Throttle,. Moreover, the V-cone itself serves as a rectifier for the flow field and has become a new type of flowmeter. The V-cone flowmeter, composed of a V-cone sensor and a differential pressure transmitter, can measure a wide Reynolds number (8 × 10)

The flow rate of various media within the range of 3 ≤ Re ≤ 5 × 107.
