I. Basic Principles and Classification of Flow Meters

1. Basic Principles

A flow meter, as the name suggests, is an instrument used to measure the speed or flow rate of oil. Its basic principle is mainly based on fluid mechanics and electromagnetism. Common flow meters include turbine, volumetric, electromagnetic, and ultrasonic types. Each type of flow meter has its unique measurement mechanism and application scenarios.

• Turbine flow meter : The flow of oil drives the turbine to rotate, and the rotational speed of the turbine is proportional to the flow rate. The flow rate can be calculated by detecting the rotational speed.
• Volumetric flow meter : The flow rate is calculated by measuring the number of times the oil passes through a fixed volume within a certain time.
• Electromagnetic flow meter : Using Faraday's law of electromagnetic induction, the flow rate is calculated by measuring the electromotive force generated by the flow of oil in a magnetic field.
• Ultrasonic flow meter : The flow rate is measured by using the change in the propagation speed of ultrasonic waves in the oil.

2. Classification and Application

Different types of flow meters have their own advantages and disadvantages and are suitable for different industrial environments.

• Turbine flow meter : Suitable for flow measurement of clean oil, high precision, fast response, often used in petroleum, chemical and other industries.
