Description

Oval Wheel Flow Meter

The Oval Wheel Flow Meter is a positive displacement flow measurement instrument designed for accurate and reliable measurement of liquids across a wide range of industrial applications. It operates by using two precision-machined oval-shaped rotors inside a measuring chamber. As liquid passes through the meter, the rotors rotate and displace a known volume of liquid, allowing the flow rate and total volume to be measured accurately.

Its positive displacement measuring principle provides excellent accuracy and repeatability, particularly for applications requiring reliable measurement of viscous and clean liquids. The meter is designed for continuous operation and can be supplied with mechanical or electronic display and output options depending on the application requirements.

Working Principle

The Oval Wheel Flow Meter works on the positive displacement principle. Inside the meter body, two oval-shaped rotors rotate as the liquid flows through the measuring chamber.

Each complete rotation of the rotors displaces a predetermined volume of liquid. The rotation is detected mechanically or electronically and converted into a flow measurement. The number of rotor rotations is proportional to the total volume of liquid passing through the meter.

This design provides accurate measurement even when the flow rate changes, making the meter suitable for applications where precise liquid measurement is required.

Advantages

The positive displacement design allows the Oval Wheel Flow Meter to provide reliable measurement over a broad operating range. It is particularly useful for liquids where accurate measurement at relatively low flow rates is required.

Its ability to handle higher-viscosity liquids makes it suitable for applications involving oils, lubricants, resins, chemicals, and other process fluids. The precision rotor mechanism also provides consistent measurement and excellent repeatability.

The meter can be configured with different body materials, connection types, display arrangements, and output options to suit specific process requirements.

Installation & Operation

The Oval Wheel Flow Meter should be installed in the correct flow direction and according to the manufacturer’s recommended installation requirements. The pipeline should be properly supported, and the liquid should be free from particles that could interfere with the precision measuring mechanism.

For optimum performance, the meter should be selected according to the flow range, liquid viscosity, operating pressure, temperature, chemical compatibility, pipe size, and required accuracy.
