Which accessory is used to monitor flow and control pump operation?

• A. Sensors
• B. Tanks
• C. Enclosures
• D. Intake Structures

Answer: (A)

Monitoring flow and controlling a pump rely on sensors that measure how much water is moving through the system and feed that information to a controller. A flow sensor provides real-time data in the main line, allowing the controller to start or stop the pump and even adjust speed or pressure to keep the desired flow. This feedback helps protect the system from running dry, cavitation, or over‑pumping.

Tanks store water, enclosures protect equipment, and intake structures bring water into the system; none of these provide real-time flow data or automated pump control.
