The OGM25/40/50D Digital Oval Gear Flow Meter is designed for measuring compatible fuels and industrial liquids, including diesel, gasoline, kerosene, HVO, and XTL. It combines an oval gear measuring mechanism with a digital display for convenient reading of measured volume and dispensing information. Available in 1″, 1.5″, and 2″ connection sizes, the series supports different flow rates and liquid transfer system requirements.

The electronic display makes measurement information easy to read during liquid dispensing and transfer operations. The catalog illustrates volume, unit price, and amount display functions.
The OGM25D, OGM40D, and OGM50D are available with different connection sizes and flow ranges, helping buyers match the meter to their system requirements.
The series lists ±0.5% accuracy and ≤0.03% repeatability. These specifications support selection for applications requiring consistent volume measurement.
The catalog describes a sealed, water-resistant structure for protection against splashing and wet industrial conditions. Confirm the applicable ingress protection rating if a specific IP rating is required.
The models differ mainly in connection size, flow range, and maximum pressure. OGM25D has a 1″ connection and a 20–200 L/min range; OGM40D has a 1.5″ connection and a 25–250 L/min range; OGM50D has a 2″ connection and a 30–300 L/min range.
The catalog illustrates measured volume, unit price, and amount. Confirm the required display functions and configuration when ordering.
The catalog lists biodiesel, diesel, HVO, XTL, gasoline, kerosene, and heavy oil applications. Actual suitability depends on fluid compatibility, viscosity, temperature, and operating pressure.
The catalog describes a sealed design intended to protect against splashing and wet industrial environments. However, it does not provide a specific IP rating in the supplied information, so a required protection rating should be confirmed before purchase.
Compare the required flow rate, connection size, maximum working pressure, liquid viscosity, and display requirements. OGM25D, OGM40D, and OGM50D have different operating ranges, so the model should match the system’s expected conditions.
Confirm the required model, connection size, maximum operating pressure, liquid compatibility, and display functions before ordering. If the installation requires a specific waterproof or ingress protection rating, request the corresponding specification from the manufacturer.
