德國*Endress+Hause電磁流量計50P80-EAOA1AAOAAAA
E+H電磁流量計是根據(jù)法拉第電磁感應(yīng)定律進(jìn)行流量測量的流量計。電磁流量計的優(yōu)點是壓損極小,可測流量范圍大。zui大流量與zui小流量的比值一般為20:1以上,適用的工業(yè)管徑范圍寬,zui大可達(dá)3m,輸出信號和被測流量成線性,精確度較高,可測量電導(dǎo)率≥1μs/cm的酸、堿、鹽溶液、水、污水、腐蝕性液體以及泥漿、礦漿的流體流量。但它不能測量氣體、蒸汽以及純凈水的流量。
當(dāng)導(dǎo)體在磁場中作切割磁力線運(yùn)動時,在導(dǎo)體中會產(chǎn)生感應(yīng)電勢,感應(yīng)電勢的大小與導(dǎo)體在磁場中的有效長度及導(dǎo)體在磁場中作垂直于磁場方向運(yùn)動的速度成正比。同理,導(dǎo)電流體在磁場中作垂直方向流動而切割磁感應(yīng)力線時,也會在管道兩邊的電極上產(chǎn)生感應(yīng)電勢。感應(yīng)電勢的方向由右手定則判定,感應(yīng)電勢的大小由下式確定:
Ex=BDv-----------------式(1)
式中Ex—感應(yīng)電勢,V;
B—磁感應(yīng)強(qiáng)度,T
D—管道內(nèi)徑,m
v—液體的平均流速,m/s
然而體積流量qv等于流體的流速v與管道截面積(πD?)/4的乘積,將式(1)代入該式得:
Qv=(πD/4B)* Ex ---------式(2)
由上式可知,在管道直徑D己定且保持磁感應(yīng)強(qiáng)度B不變時,被測體積流量與感應(yīng)電勢呈線性關(guān)系。若在管道兩側(cè)各插入一根電極,就可引入感應(yīng)電勢Ex,測量此電勢的大小,就可求得體積流量。
德國*Endress+Hause電磁流量計50P系列測量原理:根據(jù)法拉第電磁感應(yīng)定律,在磁感應(yīng)強(qiáng)度為B的均勻磁場中,垂直于磁場方向放一個內(nèi)徑為D的不導(dǎo)磁管道,當(dāng)導(dǎo)電液體在管道中以流速v流動時,導(dǎo)電流體就切割磁力線.如果在管道截面上垂直于磁場的直徑兩端安裝一對電極則可以證明,只要管道內(nèi)流速分布為軸對稱分布,兩電極之間產(chǎn)生感生電動勢:
e=KBDv (3-36)
式中,v為管道截面上的平均流速,k為儀表常數(shù)。由此可得管道的體積流量為:
qv= πeD/4KB (3-37)
由上式可見,體積流量qv與感應(yīng)電動勢e和測量管內(nèi)徑D成線性關(guān)系,與磁場的磁感應(yīng)強(qiáng)度B成反比,與其它物理參數(shù)無關(guān)。這就是電磁流量計的測量原理。
需要說明的是,要使式(3—37)嚴(yán)格成立,必須使電磁流量計測量條件滿足下列假定:
①磁場是均勻分布的恒定磁場;
②被測流體的流速軸對稱分布;
③被測液體是非磁性的;
④被測液體的電導(dǎo)率均勻且各向同性。
