What does a flow meter do in a pneumatic system?

A flow meter in a pneumatic system is essential for monitoring the air flow rate. It provides real-time data on the volume or mass of air passing through a specific point in the system, which is crucial for maintaining efficient operation and ensuring that the system is performing as intended. By monitoring the flow rate, operators can identify potential issues, optimize performance, and prevent energy waste.

Understanding the flow rate is vital because if the flow is too low, it may indicate a blockage or a malfunction in a component, affecting the overall performance of the pneumatic system. Conversely, if the flow is too high, it may lead to excess wear on components or might indicate a leak. This makes the flow meter an integral tool for troubleshooting and balancing the pneumatic system's performance.

Other options focus on measurements like air pressure, temperature, or humidity, which are important in their own contexts but do not directly reflect the flow of air in the system. A flow meter specifically targets the measurement of the flow rate, making it unique in its purpose within pneumatic applications.
