Positive Displacement Gear Flow Meters
With extensive experience in flow measurement, iCenta Controls supplies robust positive displacement flow meters for accurate, repeatable monitoring of fluid. Designed to capture precise quantities by mechanically separating the fluid into measured segments, these meters are ideal where consistency and accountability matter. Commonly used in fuel handling, lubrication systems and chemical transfer, our solutions provide dependable performance with straightforward installation and long service life.
What is a Positive Displacement Flow Meter?
A displacement flow meter is a device that measures liquid flow by trapping fixed amounts of fluid and counting how many times those volumes pass through the meter. Because it measures actual volume rather than inferring flow from velocity, it delivers exceptional accuracy and repeatability.
These meters are widely trusted in applications where precision is essential, including fuel dispensing, oil measurement, and the transfer of higher-viscosity liquids.
How Do They Work?
Positive displacement meters use internal components such as gears, pistons, or oval rotors to divide the fluid into known quantities. Each rotation or movement represents a specific volume, which is then converted into a flow reading.
This method allows accurate measurement across varying temperatures, pressures, and viscosities. The result is reliable, consistent data suited to both process control and fiscal monitoring.

Why are They Important?
Positive displacement gear flow meters provide a trusted method for obtaining precise volumetric measurement, particularly in applications involving fuels, oils, or other viscous liquids. They help to:
- Maintain accuracy and repeatability for billing, transfer, and inventory control.
- Perform reliably even when fluid properties change.
- Offer long service life thanks to rugged mechanical construction.
- Support monitoring and automation through pulse or digital outputs.
- Reduce uncertainty in critical processes where every litre counts.
With their durability and proven performance, iCenta’s meters are relied upon for consistent results in demanding environments.
What are the Positive Displacement Flow Meter Types?
At iCenta Controls, we supply a broad selection of positive displacement meters to match different operational needs. Common designs include:
Oval Gear Flow Meters: Highly accurate and well suited to clean, viscous liquids such as oils, fuels, and resins.
Rotary or Helical Gear Meters: Designed for smooth measurement at higher flow rates while maintaining precision.
Piston (Reciprocating) Meters: Often used in dispensing or custody transfer where very high accuracy is required.
Low Flow Positive Displacement Meters: Designed for applications where very small volumes must be measured with high accuracy and repeatability.
In What Industries Can They Used?
These meters are widely used wherever exact volume measurement is essential. They are particularly common in oil and gas operations, fuel distribution, chemical processing, lubrication systems, and bulk liquid transfer.
Their ability to provide consistent results independent of flow profile makes them a preferred option for applications that demand traceability and financial accuracy. Engineers across these sectors rely on iCenta’s solutions for dependable, long-term performance. Examine practical applications within our case studies.
How Can Flow Meters Benefit Your Business?
iCenta’s positive displacement flow meters give you precise control over liquid movement, helping reduce waste and improve operational visibility. Reliable, repeatable data supports better planning, accurate reporting, and confidence in every transfer.
Because they measure true volume, they are particularly valuable for verifying deliveries, managing inventory, and maintaining product quality. With robust construction and flexible integration options, our meters provide lasting performance while keeping lifecycle costs under control. For applications requiring verified accuracy, iCenta also offers UKAS calibration services, helping ensure your displacement flow meters meet industry standards and maintain long-term performance.
