2.4.8 Gas purging:

In order to remove condensation drops during start-up, flushing with dry gas for some minutes with high

flow rate is recommended.

Leak tightness:

Verification of leaks is required prior starting up of the process.

2.4.9 Inlet bends and pipe support:

Avoid pipe bends too close to the mini CORI-FLOW inlet. This might cause turbulence (especially for

gases). Use pipe supports on equal distance of mini CORI-FLOW inlet and outlet.

2.4.10 Pipe line reducers:

Avoid abrupt pipeline reducers and other obstructions in the piping. They can cause cavitation inside the

meter tubes and will result in higher pressure drops. Mount reducers outside the rigid pipe supports.

2.4.11 Vibrations:

Avoid vibrations or mechanical shocks on the mini CORI-FLOW.

Flow vibrations of pumps can influence meter performances. Therefore avoid connecting the pump

directly to the meter or install a dampening device. A flexible connection (eg. Teflon tubing) or extra loop

in the piping to neutralize vibrations is advised. Do not mount the sensor in areas subject to vibration.
