Cautions For Installation
Mounting Positions:
- Turbine flow meters should be installed at the place in compliance with the requirements below:
- Easy maintenance
- No electromagnetic interface
- No vibration
- Away from heat source
Mounting Orientation:
- All turbine flow meters are designed to measure flow in only one direction. The direction is indicated by the arrow on the body.
Required Lengths of Straight Runs
- Flow altering device such as elbows, valves and reducers can affect accuracy.
See Diagram 1 for typical flow meter system installation.
