1.Product summary：
The AFH1 series of thermal diffusion flow switches, also known as thermal flow switches or thermal mass flow switches, is a state-of-the-art device that relies on the principle of heat conduction to achieve accurate flow monitoring and control. The core working principle is to measure the change of heat dissipation rate of the heating element to determine whether the fluid is flowing or not and whether the flow rate reaches the set threshold. It focuses on accurately capturing the flow state of the fluid in the pipeline, clearly determining whether the fluid is handling the flow or not, and at the same time keenly sensing whether the flow rate hits the preset threshold. With this feature, it can output reliable switching signals, which play a key role in many industrial scenarios, whether it is to ensure the safe operation of equipment, realize precise process control, or trigger the alarm mechanism in a timely manner, it is a trustworthy and powerful assistant in the field of industrial flow monitoring.
2.Application：
AFH1 series thermal diffusion flow switches stand out in the industrial field with the features of no moving parts, high reliability, sensitivity to small flow and low pressure loss. It has become the preferred solution for monitoring fluid flow status(presence or absence of flow, flow overrun),and is widely used in many industries such as petrochemical, electric power, water treatment, pharmaceutical, food and beverage, HVAC, machinery manufacturing, etc., to escort the safety of equipments, optimize the process control, and prevent the production accidents.
