20mm Single Jet Dry Type Vane Wheel Cold Water Meter LIV-WM-BS-SJ-001 Lehry

20mm Single Jet Dry Type Vane Wheel Cold Water Meter LIV-WM-BS-SJ-001 Lehry

 

Lehry Brass Body Single Jet Dry Type Vane Wheel Cold Water Meter (Up to 50Deg/C), Anti- Magnetic Type, Hermetically Sealed Totaliser, Dry Dial, Straight Reading Type With Pulse Wire Ouput
Item Code : LIV-WM-BS-SJ-001

 

 

The Water Enters The Meter From The Inlet Of The Meter Body And Impacts The Vane Wheel At The Tip Of The Vane Blades
To Make It Rotate. The water Flows Out From The Outlet Of The body. The rotation of the vane wheel (proportional to the
Velocity Of Water Flow) Is Transmitted Directly To The Central Gear In The Vacuum-Sealed Register By The Magnetic
Coupling. The Sealed Register Totalizes And Indicates The Water Volume Passing Through The Meter
