We supply the widest range of Oval Gear Flow Meters. The Oval Gear principle of operation is not dependent on the viscosity or density of the fluid. Flow measurements are highly accurate and repeatable and are not affected by oil or chemical changes because the actual volume is being measured consistently.
An Oval Gear Flow Meter is a mechanical type of meter that works by the positive displacement principle. Oval Gear Meters are popular and cost-effective method to measure fuel and oil e.g. Diesel Fuel.
The term “Oval Gear” describes the shape of the pieces that are literally part of the rotor. There are two oval shaped rotors that are fixed into a chamber which is covered by the body of the meter. As liquid passes through from one side to the other, the gears rotate. Each rotation represents a fixed volume of liquid that passes through the meter. Various options allow the user to see the flow rate and total volume over a time period.
The Oval Gear Meter is not the only type of PD Meter but this technique using oval gears has become popular because this design is good for precision measurement. Those who are familiar with pumps will know that viscous fluids work better with gear pumps – the same applies to flow measurements of viscous liquids. Oval Gear Meters are common sight in chemical plants, marine, hydraulic applications, syrups, and certain heavy fuel.

The Gear Meters in our stock in the Philippines are manufactured for either ANSI Type Flanges or DIN Flanges. Before ordering, it is advisable to check that the flange type suits the existing piping and that face to face dimensions are accounted for. Other configurations including stainless steel, gear meters and high temperature designs using integral heat sink as well as options for outputs on request.
Oval Gear Flow Meter for Diesel Measurement in the Philippines
As industrialization increases in the main cities and provinces in the Philippines, a need arises for more energy. This need is met in several ways to assist factories and businesses operate and function both competitively and efficiently. One of the lifelines of electricity production as a sure guarantee of back-up power is Diesel generators.
Diesel is also a fuel that powers diesel vehicles. Diesel is unlike gasoline because it is heavier, but it is economical because of its lower rate of consumption. Although, we are seeing the advent and introduction of electric powered vehicles and batteries, diesel fuel is still a valuable option for powering parts of the economy and the Oval Gear Flow Meter is a trusted flow measuring device that ensures both deliveries and consumption of diesel are monitored and accounted for in a organized fashion.
Oval Gear Flow Meter Main Advantages
- Generally, an Oval Gear Flow Meter will have an inherent accuracy of 0.5% and even 0.2% when needed and is considered to be a precise method of liquid measurement, especially for chemicals and fuels.
- Totally independent of viscosity. There is no need for the Oval Gear Flow Meter to use inferential methods of flow rate calculations that depend on Reynolds numbers. The direct volume measurement principle works with either thick (High Density) or thin (Low Density) oil, fuel and chemicals.
- There is no requirement for minimum upstream and downstream lengths in Oval Gear Meter installations.
- Due to the Oval Gear rotors, chamber and complete body sturdy mechanical properties, there is no, or very little chance of flow measurement drift linked to vibration.
- One of the beauties in using the Oval Gear Flow Meter is the fact that electric power is not required for it to operate and measure flow.
- With standard and optional flow counters (mechanical registers) it is possible to measure not only total historical flow accumulation but also batch flows by simply resetting one of the counters.
- Where needed, the Oval Gear Flow Meter can also be configured and coupled with a digital display, analog and pulse outputs as well as other industry standard protocols for signaling and reporting flow consumption to control rooms or remote locations.
Recommendations for Potential Oval Gear Flow Meter Buyers
These meters are very bulky and although economically priced, much of the cost goes towards shipping the item. Knowing this, customers should plan for a gear flow meter installation well in advance in order to save costs. Although an alternative is using a cheaper propeller type flow meter, the Oval Gear Flow Meter has an overall lower cost of ownership due to its design which is superior to many other types of standard flow meters.
To ensure a greater lifetime of an Oval Gear Meter it is always advisable for the user to invest in a strainer before the inlet of the meter. Since not all diesels might be clean, the strainer will remove particles that cause unnecessary wear on the precision machined gears.
