The most appropriate device commonly used to measure flows in a water distribution system is a flow meter. Flow meters are specifically designed to measure the volume or mass of liquid flowing through a closed pipe. They can provide critical data for monitoring water usage, ensuring proper distribution, and managing infrastructure.

Flow meters come in various forms, including electromagnetic, ultrasonic, and mechanical types, each suited for different applications and types of fluids. Their ability to provide accurate real-time measurements makes them an essential tool in maintaining efficient operations within a water distribution system.

Pressure gauges, pitot gauges, and level sensors serve different purposes. Pressure gauges measure the pressure within a pipe, providing information on the system's pressure levels rather than flow rate. Pitot gauges, primarily used in aerodynamics, measure fluid velocity but are not typically used for flow measurement in water distribution systems. Level sensors are designed to measure the level of liquids in tanks or reservoirs rather than the flow within pipes. This illustrates the importance of using the correct instrument for specific monitoring needs within water systems.
