Meter Classes	Description	Bearing Material
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.
