The oval gear mechanism is designed to measure compatible liquids across a range of viscosities. The listed accuracy is ±0.5%, with repeatability of ≤0.03%.
The OGM25, OGM40, and OGM50 cover different flow requirements, allowing buyers to select a meter according to the transfer system’s expected flow rate and pipe connection.
The product uses aluminum alloy connector components and a gear-based measuring mechanism designed for regular liquid transfer operations.
The resettable counter supports individual dispensing tasks, making the meter suitable for fuel distribution and liquid transfer equipment.
The main differences are their connection sizes, flow ranges, and maximum working pressures. OGM25 uses a 1″ connection and covers 20–200 L/min; OGM40 uses a 1.5″ connection and covers 25–250 L/min; OGM50 uses a 2″ connection and covers 30–300 L/min.
The catalog lists biodiesel, diesel, HVO, XTL, gasoline, kerosene, and heavy oil among the intended applications. The liquid must be compatible with the meter’s materials and operating conditions.
Choose according to the required flow rate, pipe connection size, liquid viscosity, and system pressure. Confirm that the expected operating pressure does not exceed the model-specific maximum pressure.
Accuracy indicates how close the measured volume is to the actual volume. Repeatability indicates how consistently the meter measures under the same conditions. The catalog lists ±0.5% accuracy and ≤0.03% repeatability.
The catalog lists a maximum viscosity of 1000 cP and includes heavy oil applications. Actual suitability depends on the liquid’s properties, operating temperature, flow rate, and pressure conditions.
Confirm the required connection size, maximum operating pressure, and liquid compatibility before selecting a model. Use the product’s specified operating and calibration procedures to maintain measurement performance.
