Continuous measure,memory and show the volume of cold water of passing sealed full pipes under measurement condition.

Small flow function superior :The vane of Vertical Helical is undertaken by stainless steel ball and assembled as vertical way,so the friction resistance was reduced to lowest.

Anti-fouling function strong:Stainless steel filter inside saved charge of sole installed and troubles.Wired removable structure design,which made meter maintain capacity reduced to lowest.Water meter can work under worse water situations.If necessary ,pick out full set of mechanism core and clean quickly in assembling position.

It adopted superior material,function steady,pressure loss small,long life time.

Register make use of vacuum sealed,prevent condensation and fog in meter dial,keep reading clearly for long time.
