价格好宝帝差压流量计001248

差压流量计采用伯努利方程：压力和流速的关系。
将带开孔的平孔板插入管道中，并流向垂直。当介质
流过孔板时，其缩小的截面使流速增加并使压力减小。采
用孔板前后的压差计算流速。压差越大，则流速越大。
With pressure plate before and after the calculation
 of the flow rate. The greater the pressure,
Adjustable minimum and maximum measured flow rate
ratio of about 10: 1. And measure the conductive medium
Non-conducting medium. Since no moving parts, so
maintenance costs almost zero.
Measured medium can be cleaned medium, it can be
dirty and viscous media referrals
非导电介质。由于无可动部件，因而维护费用几乎为零。
被测介质可以是清洁的介质，也可以是脏污介质和粘性介
质。根据孔板的尺寸，有时可能必须进行介质过滤。
