ABSTRACT:
A system for determining the concentration of polymers in solution by measuring a differential pressure across a section of tubing through which the solution flows, where the tubing is bent in a loop. A drag reduction can be computed from the differential pressure value and the concentration may be determined by referring to calibration data which shows the drag reduction for known concentrations of polymers.
