How does a flow meter function in an HVAC system?

In an HVAC system, a flow meter plays a crucial role by measuring the rate of fluid flow through pipes. This measurement is essential for ensuring that the system operates efficiently and effectively. By knowing the flow rate, technicians can assess the performance of the system, optimize energy usage, and maintain the desired indoor climate.

For instance, if the flow rate is too low, it could indicate a blockage or a malfunctioning component, which may lead to inefficient heating or cooling. Conversely, an excessively high flow rate could lead to increased energy costs or potential damage to system components. The accurate measurement provided by the flow meter allows for adjustments and troubleshooting, contributing to the overall reliability and efficiency of the HVAC system's operation.

The other options describe functions that are not associated with a flow meter in an HVAC context. Regulating temperature, filtering air, and converting heat energy are all important processes in HVAC systems, but they are accomplished through different components and mechanisms, such as thermostats, air filters, and heat exchangers respectively.
