Oval Gear Flow Meter Manufacturer

As a leading Oval Gear Flow Meter Manufacturer and Supplier, Aranka Instruments LLP provides high-precision positive displacement (PD) flow meters designed for accurate measurement of viscous and non-conductive liquids. Built on proven mechanical technology developed over five decades ago, these meters feature precision-engineered oval gears enclosed in a durable casing to ensure exceptional accuracy, repeatability, and long operational life. Recognized as a reliable Oval Gear Flow Meter Manufacturer in Ahmedabad, we deliver robust instruments tailored for process industries where precision and reliability are critical.

Our Oval Gear Flow Meters work on the principle of volumetric displacement — when the liquid passes through the meter, it drives the oval gears to rotate, and each rotation displaces a fixed amount of fluid. Contactless sensors detect every gear tooth movement, generating a high-resolution pulse signal directly proportional to the flow rate. This technology enables accurate measurement of even the smallest flow volumes. As a trusted Oval Gear Flow Meter Supplier in Ahmedabad, Aranka Instruments offers meters suitable for oils, fuels, lubricants, and chemicals, providing stable performance, low maintenance, and long service life across industrial applications.

Frequently Asked Questions (FAQs)

What is an Oval Gear Flow Meter?

An Oval Gear Flow Meter is a positive displacement flow meter that measures the flow of liquids by counting the rotations of precisely machined oval gears inside the meter body.

How does it work?

The liquid flow rotates the oval gears; each rotation displaces a known volume, and sensors convert this motion into pulse signals proportional to the flow rate.

What is the accuracy of an Oval Gear Flow Meter?

Typical accuracy is around ±0.5% of reading, improving with higher viscosity liquids.

What types of fluids can be measured?

It is ideal for oils, fuels, lubricants, chemicals, and other viscous or non-conductive liquids.

Where are these meters commonly used?

They are used in oil and gas, chemical processing, lubrication systems, and dosing or batching applications.

Do Oval Gear Flow Meters require maintenance?

They have no sliding parts, ensuring minimal wear and very low maintenance requirements.

What outputs are available?

They provide pulse or frequency outputs, which can be connected to totalizers, batch controllers, or PLC systems.
