HPC Rotary Meters employ the same positive displacement operating principle as other Dresser rotary meters. Gas volumes are measured by two figure-8 impellers rotating in a chamber of known volume. Precision machining to exact tolerances ensures measurement accuracy, while materials of construction promote high quality measurement performance in the most severe conditions. As with all Dresser meters, the High Pressure Cartridge meters are designed to ANSI B109.3 specifications for Rotary Type Gas Displacement Meters. Additionally, the HPC meters meet NACE Standard MR 111075 for corrosion resistant applications.
