Standard Orifice Flowmeter

The standard orifice flowmeter is a differential pressure generating device for measuring flow. It can be used with various differential pressure meters or differential pressure transmitters to measure the flow of various fluids in the pipeline. Standard orifice flow meter throttling device includes standard annulus orifice, nozzle, etc. The orifice flow meter throttling device is used in conjunction with a differential pressure transmitter to measure the flow of liquid, steam, and gas. The standard orifice flow meter is used in petroleum, chemical, metallurgy, electric power, light industry and other departments.

The fluid filled with the pipeline, when they flow through the throttling device in the pipeline, the stream will form a local contraction at the throttling part of the throttling device, so that the flow velocity will increase and the static pressure will be low. The pressure drop, that is, the pressure difference, the greater the flow of the medium, the greater the pressure difference generated before and after the throttle, so the orifice flowmeter can measure the size of the fluid flow by measuring the pressure difference. This measurement method is based on the law of conservation of energy and the law of continuity of flow.

The intelligent throttling device (orifice flowmeter) is a new generation flowmeter that integrates flow, temperature, and pressure detection functions, and can automatically compensate for temperature and pressure. The orifice flowmeter adopts microcomputer technology and micro power consumption technology. Strong function, compact structure, simple operation and convenient use.
