Orifice Plate Flowmeter

Orifice Plate Flowmeter

Flowmeter is the eye of industrial production, and has a close relationship with the national economy, national defense construction, scientific research, plays an important role in the national economy, can be used for gas, liquid, steam, and other media flow measurement.

Works: fluid pipe, flows through the pipe when the throttle device, a beam can appear local contraction, so that the flow velocity increases, the static pressure is low, so the throttling parts before and after the pressure drop is produced, the pressure difference, the greater the flow of medium flow, in the front and rear of the throttling parts the greater the pressure difference, so the orifice meter can be measured by the size of the pressure difference to measure fluid flow. This measurement method is based on the law of energy conservation and the law of flow continuity.

Working characteristics: ① Throttling device has simple structure, firm, stable and reliable performance, long service life and low price; ② Wide application range, all single-phase flow can be measured, part of the miscible flow can also be applied; (3) Standard throttling device can be put into use without real flow calibration; The installation of the hole plate is more simple, no pressure tube, can be directly connected to the differential pressure transmitter and pressure transmitter.
