Meter Flow Rates Vs. Viscosity

  1. Determine the percent of rated capacity at which the meter will be required to operate;
  2. Determine product viscosity at system operating temperature;
  3. Plot the point on the chart where the two lines intersect;
  4. Determine the meter bearing material from construction/application table above and locate the corresponding slope on the chart.

If the plotted point is above the bearing material slope, you are outside the allowable pressure loss for the specified meter and bearing. You should either chose a larger meter, reduce flow rate, or consider alternative bearing materials.
