1  Refined petroleum products Ni-Resist*
2 Aviation and jet fuel Ni-Resist*

*(carbon bearings are standard on some meter sizes of this class, please consult factory)

  • Flow Rate:

    • 2,300 LPM (Liters Per Minute) – Indicates the maximum volumetric flow capacity.

  • Pressure Rating:

    • 150 psi (10.3 bar, 1034 kPa) – Specifies the maximum operating pressure.

  • Flange Size:

    • 4″ – The size of the inlet/outlet flange connection, likely compliant with ANSI or similar standards.

  • Construction Material:

    • Aluminum – The primary material of construction, providing lightweight and corrosion resistance.

  • Seals:

    • Buna/Viton® – Options for seals, where Buna (Nitrile) is suitable for oil and petroleum-based fluids, and Viton® offers higher chemical and temperature resistance.

  • Maximum Pressure:

    • 150 psi – Reiterated as the upper pressure limit for operation.

  • Temperature Range:

    • -40° to 185° F – Operational temperature range, indicating suitability for extreme environmental conditions.

To find the maximum meter flow rate in relation to the meter bearing material and product viscosity, use the chart below:

  • Calculate the percentage of rated capacity that the meter must function at;
  • Calculate the viscosity of the product at the operating temperature of the system.
  • Plot the intersection of the two lines on the chart.
  • Find the appropriate slope on the chart by identifying the meter-bearing material from the construction/application table above.

You are outside of the permitted pressure loss for the designated meter and bearing if the plotted point is higher than the bearing material slope. Either use a larger meter, lower the flow rate, or think about using other bearing materials.
