Meter Runs
Meter Runs
Meter runs are supplied as a complete unit of normally 1M length to ensure the necessary straight pipe length to achieve highest possible efficiency. These are available with line sizes mostly below 50mm with corner tap. These are used for the measurement of small flow rates precisely where high accuracy of flow rates is required.
Â
Types of Meter Runs
- Orifice Flange union with Meter -run.
- Orifice flange union with Carrier ring & Meter -run.
Generally Meter-run pipe is recommended with upstream length of 750mm and downstream length of 250mm. Meter runs sizes above 50mm are also available as per the customers or process requirements.
