What is the function of a gauge on the pump panel?

The function of a gauge on the pump panel primarily is to indicate the pressure of the water in the fire department's pumping system. This information is crucial for the operator to ensure that the pump is functioning correctly and that it can deliver water at the necessary pressure for effective firefighting operations. Accurate pressure readings can help the operator make decisions about adjusting the pump or hoses to maintain optimal pressure levels for the situation at hand, ensuring efficient water delivery and maintaining safety for both firefighters and civilians.

While other gauges may exist on a fire apparatus—such as those for measuring temperature, fuel levels, or other operational metrics—those are not the primary function of the gauges located on the pump panel itself. The pump panel's gauges are specifically designed to monitor the hydraulic pressure produced by the pump to maintain effective water flow and pressure during firefighting activities.
