What information does the discharge gauge provide to the operator?

Explanation:
Discharge gauge indicates the pressure being delivered to the discharge outlet. It shows the nozzle pressure you’re applying in the line, which helps you set and maintain the correct pump discharge pressure for the selected outlet. This is essential for ensuring adequate flow to the nozzle without over-pressurizing the line. It doesn’t measure flow rate, engine RPM, or water temperature—those are read from other instruments such as a flow meter, tachometer, or temperature gauge.
