1.YUNXINGYUANLI

是由電磁流量計發展而來的,其測量原理與電磁流量計相同,它基于法拉第電磁感應定律。根據弗來明右手定則,如圖1所示,導電物體通過磁場切割磁力線時,會在導體中產生感應電動勢,感應電動勢與切割磁力線的物體運動速度成比例關系。測量管是內襯絕緣材料的非磁性合金短管,兩個電極沿直徑方向穿過管壁并固定在測量管上,電極頭基本上與襯里的內表面平齊,勵磁線圈與測量管軸線垂直方向產生工作磁場B。具有導電性的水流通過電磁水表ag电子游戏赌钱時,流動方向垂直于磁場方向,水流切割水表內磁場時切割磁力線感應出電動勢E,電動勢E正比于平均流度v。電極檢測E(流量信號)并通過電纜傳送到轉換器進行智能處理,轉換輸出后有效地測量出封閉管道內導電流體的流速,流速乘以管道面積就能得到當前水流的瞬時流量。

電磁水表

ag电子游戏赌钱ER、GUANJIANXINGNENGZHIBIAODEXIANGGUANYAOQIU:

2016年,國家標準化管理委員會將水表國家標準GB/T778《冷水水表和熱水水表》列入了國家標準修訂計劃,該標準目前已發布。本次修訂的GB/T778等同采用ISO4064:2014版標準,并在內容和主要形式上與R49國際建議相統一。標準中對涉及水表產品的關鍵性能指標和內容進行了部分修正,尤其是對智能水表(電磁水表)也提出了明確的要求,標準的發布也將對新的水表檢定規程產生相應的較大影響。其中,關鍵性能指標主要有:

1.流量測量范圍(Q3/Q1):新標準將水表Q3/Q1的值從原標準的Q3/Q1=10~800,拓展至Q3/Q1=40~1000。水表流量測量范圍(Q3/Q1)的拓展,符合國家對水資源從嚴計量與控制的要求,也有利于提高我國水表產品的品質性能和國際市場的競爭力,國內部分電磁水表廠家ag电子游戏赌钱其Q3/Q1已達R800,走在了行業的前列。
