1.1 Mechanical flow meter

Mechanical flow meters are among the earliest flow meters used in oil metering, and their working principle is based on the basic principles of fluid mechanics. Common mechanical flow meters include turbine flow meters and volumetric flow meters.

• Turbine flow meter The angular velocity of the turbine rotating when fluid flows through it is proportional to the fluid flow velocity. The flow rate can be calculated by measuring the rotational speed of the turbine.
• Volumetric flow meter The flow rate of the fluid is calculated by measuring the time it takes for the fluid to flow through a fixed volume.

1.2 Electronic flow meter

With the development of electronic technology, electronic flow meters have gradually become mainstream. Their working principle mainly relies on advanced technologies such as electromagnetic induction and ultrasonic waves.

• Electromagnetic flow meter Based on Faraday's law of electromagnetic induction, the flow velocity and flow rate of the fluid are calculated by measuring the induced electromotive force generated when the fluid flows through the magnetic field.
• Ultrasonic flow meter The flow velocity of the fluid is measured by using the speed difference of ultrasonic waves propagating in the fluid, and then the flow rate is calculated.
