What can you do with a flow meter and pressure meter together?

Using a flow meter and pressure meter together allows for simultaneous measurement of both flow rate and pressure within a given system. This is advantageous in various applications, such as monitoring the efficiency of fluid transport systems, ensuring safety in pressurized environments, and optimizing process control. By connecting and reading both devices simultaneously, you can gather comprehensive data that provides insights into the system's performance. This dual capability is critical for applications like hydraulic systems, water treatment facilities, or any scenario where understanding both pressure and flow dynamics is essential.

Other choices do not capture the full potential of using both meters together. Simply connecting them without reading fails to leverage the valuable data that can be acquired. Just using one for pressure measurement does not utilize the flow meter's capabilities, leading to a more limited understanding of the overall system. Ignoring one of the devices entirely would result in missing crucial information that could impact operations or maintenance decisions. Thus, connecting and reading both meters in tandem is the most effective and informative approach.
