The SKLG series of standard orifice flowmeters are differential pressure generating devices for measuring flow. Various differential pressure gauges or differential pressure transmitters can be used to measure the flow of various fluids in a pipeline. The orifice flow meter throttling device includes a ring chamber orifice plate, a nozzle, and the like. The orifice flowmeter throttling device is used with the differential pressure transmitter to measure the flow of liquid, steam and gas. The orifice flowmeter is widely used in petroleum, chemical, metallurgy, electric power, light industry and other departments.
The fluid filled with pipes, when they flow through the throttling device in the pipe, the flow will form a local contraction at the throttle of the throttling device, thereby increasing the flow rate and the static pressure is low, so that the throttle is generated before and after the throttle The pressure drop, that is, the pressure difference, the greater the flow rate of the medium flow, the greater the pressure difference generated before and after the throttle, so the orifice flow meter can measure the flow rate by measuring the pressure difference. This measurement method is based on the law of energy conservation and the law of flow continuity.
