什么是水表?水表有什么作用

瀏覽次數: 日期:2012-9-29

  通俗的說,水表就是一種可以測量出你家用了多少水的儀表。根據國家計量檢定規程JJC162-2009《冷水水表》中的定義,水表是在測量條件下用于連續測量
  記憶和顯示流經測量傳感器的水體積的計量儀表。這是一種以其使用介質和用途命名的儀表,指用于計量流經管道的清潔冷水或熱水累積體積的流量計,廣泛用于各個領域。
  經過了近200年的發展,水表在測量原理、設計、工藝、材料、功能等方面不斷發展,已經形成了多種類、多規格的龐大家族。我們可以根據測量原理、結構形式、測量目的、測量介質等各種不用的特征給水表的前面加上修飾語,如容積式水表、預付費式水表、超聲式水表、遠傳水表、冷水水表、熱水水表等。但它的基本功能和用途依然是測量管道中流過的水的累積體積。
  對于用戶來講,水表安裝在官道上,每當用水即打開水龍頭放水時,水表上的指針就會轉動,指出通過的水量。每隔一段時間用戶需要按照水表上記錄的用水量來繳納水費。所以水表的主要作用是計量水的消耗量,保證供水方和用戶雙方貿易結算的公平和準確。
  隨著許多城市和地區“一戶一家”工程的推進,使得水表走進了千家萬戶;隨著科學技術的不斷進步和社會經濟的飛速發展,諸如智能水表、超聲式水表、電磁式水表、純凈水水表等不同原理和功能的新型水表也不斷的涌現出來,為我們的生活提供了更多的便利。
  水表是如何工作的
  由于水表有多種測量原理,種類繁多,這里僅以生活中
