• Core definition: An air flow meter is a precision instrument that converts the intake air flow into electrical signals, and is metaphorically referred to as an indispensable "data hub" in industrial automation. It provides key basis for combustion control, ventilation regulation and other aspects by monitoring real-time data such as air flow rate and flow rate.
• Working principle: Mainstream products work based on principles such as thermal, vortex, ultrasonic, and differential pressure. For example, the thermal flow rate is calculated by measuring the cooling effect of the heating element, the vortex street calculates the flow velocity by detecting the frequency of vortices generated by the fluid bypassing obstacles, and the ultrasonic wave is calculated by the time difference of sound wave propagation in the airflow.
• Diversified product types: Air flow meters are mainly divided into thermal mass flow meters, vortex flow meters, ultrasonic flow meters, differential pressure flow meters, and turbine flow meters. Different types have their own emphasis on measurement principles, accuracy, range, and applicable working conditions to meet the diverse needs from micro pipelines to large-scale industrial scenarios.
• Key performance parameters: Core parameters include measurement accuracy (some products can achieve ± 1% of reading, ± 0.5% of full range), range ratio (thermal products can reach 100:1 or even higher), response speed (some products are less than 1 second), and applicable pipe diameter, temperature, and pressure range.
• Rich industrial interfaces: Products typically support multiple signal output methods, such as 4-20mA analog output and pulse output, and integrate digital communication interfaces such as RS232 and RS485. They are compatible with mainstream industrial protocols such as Modbus RTU and can easily connect to automation control systems such as DCS and PLC.
