Instruments that measure fluid flow are collectively called flow meters or flow meters, and they are one of the most important instruments in industrial measurement. The measurement of fluid flow occupies an important position in industrial automation production and process control. Fluids can be roughly divided into liquid and gaseous media. The key component for measuring these two media is the flow sensor. Through the measurement of gas flow, people can master the flow process, perform automatic control of the production process, and implement energy management. With the application of Internet of Things technology in the industrial field, the Industrial Internet has become the direction and trend of development. Gas flow sensors are more and more widely used in the field of industrial automation. Such as natural gas, metallurgy, mining, petroleum, aviation, industrial packaging, industrial cleaning and other fields. Advanced precision manufacturing workshops, such as wafer and precision instrument manufacturing, need to be produced in clean workshops. The air in a clean workshop must reach a cleanliness level of 1,000 or even a hundred to meet production requirements. The closed clean workshop needs to be replaced with clean air every day. This requires automatic monitoring and control of flow sensors, which can not only meet the needs of production, but also control unnecessary excessive energy consumption and effectively improve the input-output ratio. In addition, there are industrial products that require nitrogen, ammonia, inert gas, etc. for production, which are inseparable from gas flow sensors for measurement and monitoring. For example, the AFM3000 series of flow sensors from ASAIR Electronics have the characteristics of high measurement accuracy, fast response, strong stability, etc., adapt to different harsh operating environments, and help the development of various fields of industry. AFM3000 series of flow sensors from ASAIR Electronics According to different industrial uses, the applied sensors can be divided into two types: flow and micro flow. For example, oxygen needs to be added for catalytic reaction, nitrogen filling of potato chip packaging, etc., must be controlled by micro-flow in order to achieve the desired monitoring effect. ASAIR Electronics' micro flow sensor AFS01 is one of the representative products used in this field. ASAIR Electronics' Micro Flow Sensor-AFS01 Gas flow parameters are important data necessary for industrial production, scientific experiment measurement and various economic accounting, and an important part of energy measurement. In today's era when the degree of industrial automation is getting higher and higher, the role of gas flow sensors in the national economy is becoming more and more obvious. In the future, it is an inevitable trend for the flow sensor to develop towards digital, intelligent, multifunctional and networked. ASAIR Electronics seizes the pulse of the development of the times and contributes to the development of domestic industrial automation.

Differential pressure sensor is one of the indispensable key parts of medical equipment such as ventilator and anesthesia machine, and it is the most technologically content part of the medical equipment field. Differential pressure sensor is a special type of pressure sensor, which uses the new "thermal MEMS" semiconductor sensing technology to achieve high-precision differential pressure measurement. The differential pressure sensor contains a heater and temperature sensors placed symmetrically on both sides of the heater. Schematic diagram of differential pressure sensor When the heater (ie, resistance) is heated by current, a steady-state temperature curve is formed around the heater. When the gas (medium) is not flowing, two symmetrical temperature sensors will detect the same temperature. When the gas flows, such as from left to right, the temperature reading of the sensor is higher on the right than on the left. Since the temperature difference is directly proportional to the flow rate, we measure the differential pressure value by measuring the temperature difference between two temperature sensors.
