Which device is typically used to measure flow?

• A. Flowmeter
• B. Weir
• C. Hydrometer
• D. Barometer

Answer: (A)

A flowmeter is specifically designed to measure the rate of flow of liquids or gases. It provides continuous measurements that are essential for monitoring the performance of a water distribution system. Flowmeters can be found in various types, such as positive displacement, turbine, electromagnetic, and ultrasonic flowmeters, each suited for different applications and types of fluids. While the other devices listed have their own specific functions, they are not primarily intended for measuring flow rates. A weir, for example, is a structure used to measure flow indirectly by creating a controlled width of water flow, but it does not measure flow directly like a flowmeter. A hydrometer is used to measure the specific gravity (density) of liquids, which provides information about the substance but not the flow rate. A barometer, on the other hand, measures atmospheric pressure and has no relation to flow measurement in liquids. Thus, the flowmeter is the most appropriate choice for measuring flow.
