品牌：RETZ/我們一直致力于流體控制和測控領域的持續(xù)創(chuàng)新，始于2005……進口孔板流量計作為過程自動化控制系統(tǒng)的檢測儀表和測量物料數(shù)量的總量表，被廣泛適用于煤炭、化工、交通、建筑、輕紡、食品、醫(yī)藥、農業(yè)、環(huán)境保護各個領域

進口孔板流量計原理及用途Principle and purpose

孔板流量計是將標準孔板與多參量差壓變送器（或差壓變送、溫度變送器及壓力變送器）配套組成的高量程比差壓流量，充滿管進口孔板流量計原理及用途.jpg道的流體流程管道內的節(jié)流裝置，在節(jié)流件附近邊成局部收縮，流速增加，在其上、下游兩側產生靜壓力差（如圖）。在已知有關參數(shù)的條件下，根據(jù)流動連續(xù)件原理和伯努利方程可以推異出辨壓與流量之間的關系（流量愈大，所產生的壓差愈大）而求得流量。

Orifice plate flowmeter is a high range ratio differential pressure flow device composed of a standard orifice plate and a multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter, and pressure transmitter). The throttling device in the fluid flow pipeline that is filled with the pipeline locally contracts near the throttling component, increases the flow rate, and generates a static pressure difference on both upstream and downstream sides (as shown in Figure 1). Under the condition that relevant parameters are known, the relationship between differential pressure and flow rate can be inferred based on the principle of flow continuity and Bernoulli equation (the larger the flow rate, the greater the pressure difference generated) to obtain the flow rate.
