1. What is flow sensor?

A flow sensor is a sensor used to measure the flow rate (flow rate) of a fluid (liquid or gas). It senses the flow of fluid through different technical means and converts this information into electrical signals or digital signals for use by other devices or systems. There are many types of flow sensors, and common ones include vortex flow sensors, ultrasonic flow sensors, magnetic flow sensors, etc.

2. Working principle of flow sensor

Different types of flow sensors have different working principles, but they can generally be summarized into two types: one is to measure the rate of fluid flow through changes in physical mass or energy; the other is to detect the physical characteristics of fluid flow. Flow measurement. Taking the vortex flow sensor as an example, it calculates the flow rate of the fluid by measuring the rotation rate of the turbine to obtain the flow value.

3. Application fields of flow sensor

Industrial field: Flow sensors are widely used in industrial automation control systems to monitor the flow of liquid or gas in pipelines and realize automated and intelligent management of the production process.

Environmental monitoring: flow sensors play an important role in environmental monitoring and can be used to monitor air quality, water quality and other parameters to ensure environmental safety and health.

Smart home: In the field of smart home, flow sensors can be used to monitor household water and gas consumption to achieve intelligent energy saving and improve the quality of life.

Medical field: In medical equipment, flow sensors are widely used in respirators, infusion pumps and other equipment to ensure the accuracy and safety of the medical process.
