2 Commissioning of primary Flow Meter 1. Open feed or Open discharge provide sluice under pass if full pipe cannot be assured. This ensures full pipe under No flow condition. 2. Straight langhts of maximum 10D on upstream and minimum 5D on Down stream so if disturbances 3. referred Locations: Locations 1 and 2 are recommendedlocations, Location 3 is the highest point in pipe run. This location is not recommended since air bubbles collect in the metering tube which will lead to faulty measurements.location 4 is also not recommended since at zero flow the line will get drained and hence will give false measurements 4. In case of heavily contaminated Fluids, the primary flow tube should be installed with a Bypass pipeline and isolation valves so that it can be removed for cleaning without interrupting operation.
