The VSAN Mechanical Oval Gear Flow Meter is a highly accurate Positive Displacement (PD) flow measuring instrument designed for precise volumetric measurement of high-viscosity and low-viscosity liquids. Engineered using the proven Oval Gear Positive Displacement Principle, the flow meter measures the actual volume of liquid passing through the meter with exceptional accuracy, making it an ideal choice for industrial applications where reliable and repeatable flow measurement is essential.
Unlike electronic flow meters, the VSAN Mechanical Oval Gear Flow Meter operates without requiring an external power supply. The flow rate and totalized volume are displayed through a mechanical register, making it suitable for remote locations, hazardous environments, and applications where a simple, dependable, and cost-effective flow measurement solution is required.
The meter consists of two precision-machined oval gears housed within a specially designed measuring chamber. As the liquid flows through the chamber, the gears rotate smoothly, and each complete rotation displaces a fixed volume of liquid. This positive displacement measuring method ensures excellent accuracy with minimal influence from variations in pressure, viscosity, or flow conditions.
Manufactured using premium-quality materials such as Cast Iron, Aluminium, SS304, and SS316, the VSAN Mechanical Oval Gear Flow Meter is suitable for measuring a wide range of liquids including diesel, petrol, kerosene, furnace oil, lubricating oil, hydraulic oil, transformer oil, edible oil, chemicals, paints, solvents, resins, molasses, syrups, and other viscous fluids.
The rugged mechanical register provides clear and easy-to-read cumulative flow readings without requiring batteries or electrical power. Its compact design, robust construction, low maintenance requirements, and long operational life make it a preferred choice for fuel dispensing systems, lubricant monitoring, oil transfer, batch loading, and industrial process applications.
Designed for reliable operation in demanding industrial environments, the VSAN Mechanical Oval Gear Flow Meter offers outstanding durability, minimal pressure loss, and long-term measurement stability, making it an economical and dependable solution for accurate liquid flow measurement.
The VSAN Mechanical Oval Gear Flow Meter operates on the Positive Displacement (PD) Principle.
Inside the measuring chamber, two precision-engineered oval gears rotate freely as the liquid enters the flow meter. Each rotation of the gears traps a fixed quantity of liquid between the gear teeth and the chamber wall, transferring it from the inlet to the outlet.
The rotational movement of the gears is mechanically transmitted through a gear train to the mechanical register. The register continuously records the total volume of liquid that has passed through the meter and displays the reading in litres or cubic metres.
Since each rotation represents a fixed volume of liquid, the measurement is highly accurate and largely unaffected by changes in flow profile, viscosity, or operating pressure. The positive displacement design ensures consistent performance even at low flow rates, making it ideal for viscous liquids and precision dispensing applications.
As the instrument requires no electrical power, it provides reliable and continuous flow measurement in remote locations and suitable hazardous-area applications while minimizing maintenance requirements.
The VSAN Mechanical Oval Gear Flow Meter is widely used for accurate volumetric measurement of clean, lubricating, and viscous liquids across various industrial applications.
