Forging Flange ORIFICE FLANGE WN A-105 2" 300# RF CED.XS
The principle of
Full pipe flow, when they flow through the pipe of the throttle device, a beam to local contraction at the throttling of the throttle device, 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, the throttling produce the greater the pressure difference before and after, so can be measured by the size of the pressure difference to measure fluid flow. This measurement method is based on the law of energy balance and the law of flow continuity.
Intelligent throttle device (flowmeter) is a new generation of flowmeter which integrates the function of flow, temperature and pressure detection and can automatically compensate the temperature and pressure. The meter adopts advanced microcomputer technology and new micro power consumption technology, with strong function, compact structure, simple operation and convenient use.
The characteristics of
Throttling device structure is easy to copy, simple, firm, stable and reliable performance, long service life, low price.
The orifice plate calculation adopts international standard and processing
Wide application range, all single - phase flow can be measured, some miscible flow can also be used.
The standard throttling device can be put into use without real flow calibration.
The one-type orifice plate is more simple to install, without pressure lead tube, can be directly connected to the differential pressure transmitter and pressure transmitter.
