AS-W Series
Since AS-W flow meter covers wider range from small to large flow rate, it contributes to cost saving and convenient facility management. At the same time, it saves the cost of redundant governor and piping.
･ Non-moving parts results in not degrading meter performance. It eventually makes needless to repair the parts and refuel the lubricant oil.
･ Because of the pressure loss being closely “0”, it can get rid of the pressure shortage risk.
･ Because of lightweight and compact feature, it enables easy installation and needs less space
