Ventilation ducts, referred to as air ducts, are metal or composite pipes used in ventilation and air-conditioning projects in industrial and civil buildings. They are a type of municipal infrastructure designed to circulate air and reduce the concentration of harmful gases. As a common product in our lives, ventilation ducts are now widely used in the market, such as: industrial building ventilation, underground space, safety ventilation, agricultural fields, etc.
The flow in the pipe in the ventilation duct is caused by the pressure difference of the gas at both ends of the pipe. Except for high-temperature gas, it is a constant volume movement. Due to the change in cross-section, the flow rate changes accordingly, and the dynamic pressure and static pressure in the pipe transform into each other. Thus "pipe flow velocity" is often used to mean the flow rate in a closed pipe under pressure . Enclosed ducts are usually round in shape, but can also be square or rectangular.
This way very small changes in flow rate can be detected. To obtain higher flow velocities, the temperature sensor can be connected to a thermostatic anemometer. And because the gas flow sensor AFE-01 is manufactured by a professional European flow manufacturer, it has a very small size, dual flow direction detection, detection of the flow of small mass objects, simple signal processing circuit and calibration, completely fixed mechanical components, and excellent repeatability. It has the characteristics of durability and long-term stability and is suitable for use by medical, instrumentation industries and OEM customers.
