As the Fuel Consumptions Systems comprises two EGM positive displacement meters and an F127 flow instrument it can accurately measure fuel consumption of combustion engines. This is possible, as the FCS can correct the temperature differences from the inlet to the outlet of the engine.
The renowned positive displacement meters give you an accurate and economic way of measuring you fuel consumption for all engines sizes. This is possible because of the:
To reach this high accuracy the kit selection is crucial.
The Fuel Consumption Kit might consist of the same items. However, the size of the engine is important as is in direct correlation with the rate of the flow that determines the change of the meter and the process connection.
This becomes apparent, as the average diesel loop system would have 3,5 times more fuel in its line than what the engine consumes at full load.
Selecting the correct kit based on the engine’s power output is, therefore, essential to secure accuracy and the durability of the positive displacement meter.
The graph here can guide you in determining the required size of the kit for you.

The Oval Gear Meters use a measuring principle, where a pair of oval-shaped gears in a measuring chamber rotate by the force of the liquid on these. The liquid flows into a chamber and is sealed off once the chamber is full and produces either an electronic pulse or drives a gear to register the volume as it exits the chamber.
As illustrated in the example on the right, the pulse is generated because the (green) liquid is sealed from both the inlet (red liquid) and exit (blue liquid). This set up would produce four pulses as the meter transmits four identical volumes for every cycle.
Thus, it matters which Flowmeter you choose because the simplest meters register each time a bucket is filled. Here the total volume would be the sum of the number of buckets filled. In the complex meters the discrete volumes passed each time can be summed together to see the overall volume passing through the meter.
The FLOMEC OM Series is an oval gear meter designed for accurate measurement of clean liquids, including gasoline, diesel fuel, and other petroleum-based products, as well as chemicals and food-grade fluids.
A: These meters are commonly used in marine fuel consumption monitoring, industrial process control, chemical dosing, and food & beverage production.
The OM Series uses precision oval gears that rotate as liquid flows through, accurately measuring each volume of liquid. The high repeatability and accuracy (±0.5% of reading) make it suitable for critical applications.
Depending on the OM Series model, flow rates range from 1 L/min to 2,500 L/min, making it versatile for various fluid transfer applications.
The FLOMEC oval gear meters are available in different materials, including stainless steel for aggressive chemicals and hygienic applications, aluminum for fuels like gasoline and diesel fuel, and PPS (polyphenylene sulfide) for cost-effective solutions.
The maximum pressure rating varies by model, with some meters handling pressures up to 1,000 PSI (69 bar).
Yes, FLOMEC oval gear meters are ideal for measuring high-viscosity fluids such as oils, lubricants, and syrups, with minimal pressure drop.
These meters are designed for clean liquids such as:
The OM Series offers pulse output, making it easy to connect to PLCs, fuel consumption monitoring systems, and remote displays.
The pulse models typically operate on 5–24V DC, depending on the specific configuration.
The meter should be installed horizontally or vertically, ensuring proper flow direction, avoiding air bubbles, and allowing for accurate fuel consumption measurement.
These meters are designed for long-term reliability with minimal maintenance, but periodic cleaning and inspection of the oval gears and seals can help maintain accuracy.
Check for:
Yes, the meter can be field-calibrated to ensure repeatability and accuracy over time.
Selecting the correct model depends on factors like fluid type, pressure requirements, flow rate, material compatibility (stainless steel, aluminum, PPS), and output needs.
