Flow Verification Instructions:
- To verify flow, record the differential pressure reading which is the difference between the reading taken on the Hi Port and the Low Port of the Mesurmeter.
- Use corresponding pressure drop chart for Mesurmeter size and Cv to determine actual flow
- For High concentrations of antifreeze compounds, consult Hays Tech Tip on Propylene Glycol.
