Precise Air Flow Measurement Improves Flotation Cell

The customer’s process review had revealed that the amount of unobstructed pipe straight run was insufficient and affected the accuracy of the flow meters The flotation cells required an air flow rate that varied from 35 to 1 050 SCFM depending on the location and production volume and at pressures from 4 to 7 psig 03 bar g to 05 bar g
