I. Basic Principles and Technical Classification of Flow Meters

1.1 Basic Principles of Flow Meters

A flow meter is an instrument used to measure the flow rate of fluids (liquids or gases). Its basic principles are mainly based on the following physical phenomena:

• Differential pressure principle : By installing a restriction device in the pipeline, the fluid velocity increases, and the pressure decreases, allowing the flow rate to be calculated based on the pressure difference.
• Electromagnetic induction principle : Using Faraday's law of electromagnetic induction, the electromotive force generated when a conductive fluid passes through a magnetic field is measured, and then the flow rate is calculated.
• Ultrasonic principle : By measuring the time difference or frequency difference of ultrasonic waves propagating in the fluid, the fluid velocity and flow rate are calculated.
• Turbine principle : When fluid passes through a turbine, the turbine rotation speed is proportional to the fluid velocity. The flow rate is calculated by measuring the turbine speed.

1.2 Technical Classification of Flow Meters

According to different measurement principles, flow meters can be classified into the following categories:

• Differential pressure flow meter : Such as Orifice plate flow meter and Venturi flow meters, etc.
• Electromagnetic flow meter : Suitable for measuring conductive liquids.
• Ultrasonic flow meter : Suitable for measuring clean fluids and fluids containing impurities.
• Turbine flow meter : Suitable for measuring high-precision liquid and gas flow.
• Mass flow meter : Directly measures the mass of the fluid, suitable for occasions with high precision requirements.
