I. Basic Principles and Classification of Flow Meters

1.1 Basic Principles

The working principle of flow meters is mainly based on physical principles such as fluid mechanics and electromagnetic induction. By measuring the speed or volume of fluid passing through a specific cross-section, the flow rate is calculated. Common types of flow meters include electromagnetic flow meters ultrasonic flow meters, turbine flow meters, and differential pressure flow meters, etc.

1.2 Main Classifications

• electromagnetic flow meters : Utilizing Faraday's law of electromagnetic induction, the flow rate is calculated by measuring the induced electromotive force generated by conductive liquid in a magnetic field.
• Ultrasonic flow meters : Measure flow rate by using the change in the propagation speed of ultrasonic waves in the fluid. Methods include time-difference, frequency-difference, and Doppler methods.
• Turbine flow meters : The fluid drives the turbine to rotate; the turbine's rotational speed is proportional to the flow rate. The flow rate is calculated by measuring the rotational speed.
• Differential pressure flow meters : Measure flow rate using the pressure difference generated when fluid flows through a throttling device, such as orifice plate flow meters and Venturi flow meters.
