| WATER METER >SINGLE JET METERS SYSTEMS |
| DEFINITION: |
|
Set of moving device that fitted into a closed conduit driven directly by water flow. Its turbine rotor rotates about the axis which is perpendicular to water flow. |
| |
|
| WORKING PRINCIPLES: |
| |
Water flow drives vane rotate. Rotating times which is proportional to water flow speed are gathered, hence total volume passed through water meter is recorded. |
