llustrated as drawing 1, when the liquid pass through main hole’s plate, the pressure difference between 

front side and back side happens, there is a respondent function relation between the pressure difference 

and flow speed. Installing a small rotor flowmeter on the in-outlet of branch, i.e. to make that the flow

volume through small rotor flowmeter is same to the volume through main pipe, therefore the flow volume’s

data in main pipe can be read through buoy position and scale on small rotor flowmeter. The cut-off valve 

installed between measure pipe and indicator can make the flowmeter’s take-down or repair conveniently 

when the main pipe is being normal working situation

Temperature Limit:  SS304: 0~120℃ 

Accuracy: ±2.5%

Max. Working pressure: 1.0MPa

The product can be changed different directions illustrated as drawing 3. the flow direction can as: bottom-top,

left-right, right-left and top-bottom. It is easy to change flow direction on the spot 

Attention:special flow volume’ specification can be customized accodding to technical data provided by customers.
