產品詳情
差壓式孔板流量計是大多數情況下不同于傳統的節流裝置,它具備新一代差壓穩定系統,能夠在差壓變化的情況下保證0.05%的精度去測量流量,這也是差壓式孔板流量計暢銷市場的主要原因。如果說孔板流量計是流量儀表測量中的一個小黑馬,那么差壓式孔板流量計就是流量儀表行業的黑科技代表,因為無論從外觀和組合復雜程度上來說,差壓式孔板流量計都是比較復雜的。該流量計的結構也不簡單,要配齊差壓變送器、三閥組、表彎、多孔法蘭焊接等,如果其中一項做的不好,那么合成時候就會影響其測量精度。koc壓力變(bian)(bian)(bian)送(song)器_差壓變(bian)(bian)(bian)送(song)器_液位變(bian)(bian)(bian)送(song)器_溫度變(bian)(bian)(bian)送(song)器

充滿管道的流體,當它們流經管道內的流量孔板時,流速將在流量孔板的節流處形成局部收縮,從而使流速加快,靜壓力降低,于是在標準孔板前后便產生了壓力降或叫壓差,介質流動的流量愈大,在流量孔板前后產生的壓差也就愈大,所以可通過測量壓差來測量流體流量的大小。這種測量方法是以流動連續性方程(質量守恒定律)和伯努利方程式(能量守恒定律)的原理為基礎的。koc壓(ya)力(li)變送(song)(song)器(qi)_差壓(ya)變送(song)(song)器(qi)_液位變送(song)(song)器(qi)_溫度變送(song)(song)器(qi)
