50W1F-H50A1A10B7AW德國(guó)E+H電磁流量計(jì)
50W3H-H50A1A10A7AW,50W1F-H50A1A10B7AW:德國(guó)E+H恩格斯豪50W3HH50A1A10A7AW,50W1F-H50A1A10B7AW,E+H電磁流量計(jì)在污水處理中就會(huì)用到:
1進(jìn)水管;
2初沉池到貯泥池泥量檢測(cè);
3污泥泵房剩余、污泥流量檢測(cè);
4污泥泵房回流污泥流量檢測(cè);
5二沉池配水井的出水流量檢測(cè);
6消化池進(jìn)泥量檢測(cè);
7消化池出泥量檢測(cè);
8絮凝池藥劑進(jìn)量檢測(cè)等等。
E+H流量計(jì)比對(duì)的方法與標(biāo)準(zhǔn)表校準(zhǔn)法
流量計(jì)比對(duì)的方法與標(biāo)準(zhǔn)表校準(zhǔn)法相似,應(yīng)在足夠長(zhǎng)的時(shí)間內(nèi)比較標(biāo)準(zhǔn)表積算總量‰和被校表積算總量V。
1.用皮托管或其它插入式電磁流量計(jì)的請(qǐng)參照IS03966用皮托管比對(duì)大口徑電磁流量計(jì)流量值,這樣就必須在流量計(jì)上游(或下游)適當(dāng)位置預(yù)留插入皮托管或其他插入式流量計(jì)的孔或閥。
2.用超聲流量計(jì)現(xiàn)在較多用可移動(dòng)夾裝式超聲流量計(jì)(即便攜式超聲流量計(jì))作流量比對(duì)。若電磁流量傳感器裝于地下儀表井時(shí),應(yīng)在儀表井內(nèi)電磁流量傳感器上游(或下游)預(yù)留夾裝超聲換能器所需管段和空問。若是新建管線則在未裝流量傳感器之前,精確測(cè)量擬裝夾裝式超聲換能器管段的內(nèi)徑,并記錄在案,計(jì)算準(zhǔn)確的流通面積,以便比對(duì)時(shí)應(yīng)用。內(nèi)徑測(cè)量方法可參照J(rèn)JG640J94《差壓式流量計(jì)檢定規(guī)程》。
