EMCO Rectangular Venturi Tube Welded Sheet with Weld end Connection FKVR

Manufactured by  

The EMCO rectangular venturi tubes are used in air ducts or furnaces as primary elements in flow measurement of gas according to the differential pressure principle.
The rectangular venturi tube has single or double plane contraction.
The rectangular venturi tube is used where the circular classical venturi tube is impossible or impractical to use.
