Oval Gear Flow Meter
The oval gear flow meter is a positive displacement (PD) flow measurement device designed for precise volumetric measurement of liquids, especially high-viscosity and low-flow-rate media.
By mechanically trapping and transferring fixed volumes of fluid, the meter provides stable and repeatable measurement independent of flow profile, pressure, or fluid conductivity.
Instrava oval gear flow meters are engineered for industrial applications requiring high accuracy, strong repeatability, and reliable performance under changing process conditions, including viscous, lubricating, or chemically aggressive fluids.

Oval Gear Flow Meter Working Principle
The oval gear flow meter operates on the positive displacement principle.
As fluid enters the measuring chamber, it drives two synchronized oval gears to rotate. Each rotation traps and transfers a fixed and known volume of liquid from the inlet to the outlet.
The rotation of the gears is detected by a sensor, generating pulse signals proportional to the volumetric flow rate. Because each pulse corresponds to a precise displaced volume, the flow meter delivers highly accurate instantaneous flow and totalized flow measurement.
Oval Gear Flow Meter Structure & Reliability
Dual oval gear design ensures continuous and smooth fluid transfer
Precision-machined measuring chamber for long-term accuracy
Bearings and gears optimized for viscous and lubricating media
Robust housing materials for pressure and corrosion resistance
Low internal leakage for improved measurement accuracy
This mechanical simplicity results in excellent long-term stability and low maintenance requirements.

Oval gear flow meters operate on the positive displacement principle, mechanically transferring fixed fluid volumes. This makes them highly insensitive to viscosity changes, allowing stable and accurate measurement of heavy oils, resins, polymers, and other high-viscosity media.
Unlike velocity-based meters, oval gear flow meters maintain excellent accuracy at low flow rates because each gear rotation represents a fixed volume. This makes them ideal for low-flow dosing, batching, and precision transfer applications.
Pulse output provides a direct digital representation of volumetric flow, where each pulse corresponds to a defined volume. This enables precise totalizing, batching, and easy integration with PLC, DCS, and industrial automation systems.
No. Because oval gear flow meters measure actual displaced volume, their accuracy is largely unaffected by pressure changes or flow profile disturbances, provided the system operates within the rated pressure range.
Yes. Oval gear flow meters are well suited for intermittent, pulsating, or start-stop flow conditions, as the mechanical displacement principle ensures accurate totalization even during unstable flow patterns.
Maintenance is minimal when measuring clean, lubricating liquids. Periodic inspection focuses on gear wear and signal stability, especially in high-viscosity applications, ensuring long-term measurement reliability.
