This graph is intended as an aid to determine the pressure drop of the measuring device as part of a system, allowing engineers to calculate the most
economical components for their systems, i.e. pump selection would be determined on the total system pressure drop; the lower the pressure drop,
the lower the cost of the pumping components.
The graph above represents the pressure drop for standard and high-viscosity (special cut) rotors at various viscosities. Viscosities are in centipoise and
the pressure drop is in psi and bar. As will be noted, the maximum pressure drop is shown at 14.5 psi (1 bar); although this is achievable, it is not
recommended. The % of maximum flow rate represents the flow rate of any given meter model and can be applied to the above graph, i.e. 10% of the
FPD-1005 model would be 3.2 gallons (12 liters).
