An air flow transmitter is a device used to measure the rate of air flow in a given system. It is typically used in industrial settings to monitor the flow of air in ventilation systems, air conditioning systems, and other air-handling systems. The air flow transmitter works by measuring the pressure difference between two points in the system. This pressure difference is then converted into a signal that can be read by a computer or other monitoring device. The air flow transmitter is a critical component in many industrial systems, as it helps to ensure that the air flow is within the desired range and that the system is operating efficiently. Additionally, the air flow transmitter can be used to detect problems in the system, such as blockages or leaks, and alert the operator to take corrective action.
