class="NyNewsdetail_con"> <div>　　A+K孔板流量計采用超聲回波技術(shù)，通過測量流體液位高度，再經(jīng)過儀器內(nèi)部的微處理器運(yùn)算得到流量。由于是非接觸測量，它能在較惡劣的環(huán)境中應(yīng)用。該儀表在微機(jī)控制下，發(fā)射和接受明渠，根據(jù)傳輸時間計算出儀表距被測液面的距離，從而得到液位高度，由于該液位與流量之間有一定的比例關(guān)系，因此可根據(jù)計算公式得到液體流量。</div><div> </div><div>　　在計量時必須使用量水堰槽，在明渠上安裝量水堰槽后，必須按照規(guī)范使流量與液位建立對應(yīng)關(guān)系。根據(jù)渠道內(nèi)水的流態(tài)及渠道內(nèi)流量的大小選擇量水堰槽的類型：當(dāng)所測水流的流量小于40L/s時，采用直角三角堰；當(dāng)水流的流量大于40L/s時，采用巴歇爾槽；當(dāng)水流流量大于40L/s且明渠的水位落差較大時，采用矩形堰。</div><div> </div><div>　　今天咱們來了解下A+K孔板流量計所具備的主要功能：</div><div> </div><div>　　1、在數(shù)據(jù)上可測量并記錄流量的正負(fù)值，該儀表會保存正累積量和負(fù)累積量，保證被測流量凈累積量的準(zhǔn)確度。</div><div> </div><div>　　2、在通信上可以選擇多種通訊協(xié)議，4-20mA、脈沖、繼電器、RS485、Modbus、M-bus、Hart、批量控制器等，通過協(xié)議將數(shù)據(jù)傳到PC或者云端，實現(xiàn)物聯(lián)，不同的通訊協(xié)議適用于各個不同的環(huán)境工況中。</div><div> </div><div>　　3、在維護(hù)巡檢上可導(dǎo)出檢測管道數(shù)據(jù)，數(shù)據(jù)包含測量時間、流量、流速、正負(fù)凈累積量，較低可設(shè)置1秒間隙導(dǎo)出，適合管道巡檢工作。</div><div> </div><div>　　4、在安裝選擇上可選擇外夾式、管段式和插入式，不同的工況所需要的安裝方式不同，可保持整體一致性。</div><div> </div><div>　　5、在被測流體上可測量非導(dǎo)電流體和腐蝕性流體，選擇外夾式時流量計對管道不會有破壞，不會導(dǎo)致后期管道泄露的情況發(fā)生。</div> </div> <div id="5f5dtfj" class="ly_PrevNext"> <ul> <li>上一篇：<a
