How to choose the correct D differential pressure value for Tianjin pressure transmitter parameters and integrated orifice flowmeter?Xi'an Huaheng Instrument Online Answer:Integrated orifice plate flowmeter is a differential pressure generating device for measuring flow.It can measure the flow of various fluids in pipelines with various differential pressure meters or differential pressure transmitters.

 

　　節(jié)流裝置包括環(huán)室孔板，噴嘴等。節(jié)流裝置與差壓變送器配套使用，可測(cè)量液體、蒸汽、氣體的流量，它廣泛應(yīng)用于石油、化工、冶金、電力、輕工等部門(mén)。

 

　　The throttling device includes a ring chamber orifice plate,a nozzle,etc.The throttling device is used with differential pressure transmitter to measure the flow of liquid,steam and gas.It is widely used in petroleum,chemical,metallurgical,electric power,light industry and other departments.

 

　　作為國(guó)內(nèi)較早研發(fā)和生產(chǎn)孔板流量計(jì)的廠家，生產(chǎn)的一體化孔板流量計(jì)質(zhì)量?jī)?yōu)良，性能卓越，在國(guó)內(nèi)眾多工業(yè)現(xiàn)場(chǎng)得到廣泛應(yīng)用。

 

　　As an early manufacturer of orifice flowmeter in China,the integrated orifice flowmeter has excellent quality and excellent performance,and has been widely used in many industrial sites in China.

 

　　V錐流量計(jì)是利用V錐體在流場(chǎng)中產(chǎn)生的節(jié)流效應(yīng)，通過(guò)檢測(cè)上下游壓差來(lái)測(cè)量流量。與普通節(jié)流件相比，它改變了節(jié)流布局，從中心孔節(jié)流改為環(huán)狀節(jié)流。

 

　　V-cone flowmeter uses the throttling effect produced by V-cone in the flow field to measure the flow rate by detecting the pressure difference between upstream and downstream.Compared with the ordinary throttle,it changes the throttle layout from the central orifice throttle to the circular throttle.

 

　　實(shí)踐使用證明，V錐流量計(jì)與其他流量?jī)x表相比，具有長(zhǎng)期精度高、穩(wěn)定性好，受安裝條件局限小、耐磨損、測(cè)量范圍寬、壓損小、適合贓污介質(zhì)等優(yōu)點(diǎn)。而且V錐體本身作為流場(chǎng)的整流器而成為一種具有獨(dú)特性能的優(yōu)異的新型流量計(jì)。由V錐傳感器和差壓變送器組合而成的V錐流量計(jì)，可精確測(cè)量寬雷諾數(shù)(8×103≤Re≤5×107)范圍內(nèi)各種介質(zhì)的流量。

 

　　Compared with other flow meters,V-cone flowmeter has many advantages,such as high long-term accuracy,good stability,small installation conditions,wear resistance,wide measurement range,small pressure loss and suitable for smuggled media.Moreover,as a rectifier of flow field,V-cone becomes a new type flowmeter with unique performance.A V-cone flowmeter composed of a V-cone sensor and a differential pressure transmitter can accurately measure the flow of various media in a wide Reynolds number range(8*103
