What is the purpose of a flowmeter?

The purpose of a flowmeter is to monitor the flow rate of liquids. Flowmeters are critical instruments used in various applications, including wastewater treatment, to measure the volume or mass of a fluid moving through a pipe over a certain period. By tracking this flow rate, operators can assess process efficiencies, ensure systems are running as intended, and make necessary adjustments to treatments or processes. Maintaining the correct flow rate is essential for ensuring proper treatment and minimizing environmental impacts. This capability is essential in managing wastewater systems effectively, ensuring they function within their designed parameters. The other options, while pertaining to different types of measurements, do not accurately describe the primary function of a flowmeter.
