What is the function of the digital flow meter in relation to the large diameter discharge?

The digital flow meter plays a crucial role in gauging the flow rate from the pump to the waterway. This function is essential in firefighting operations as it allows responders to monitor the amount of water being discharged, which in turn helps ensure that adequate water is available for firefighting efforts. By measuring the flow rate, firefighters can optimize their water usage, assess the effectiveness of their water supply, and make informed decisions about resource allocation during an incident. This real-time information is vital for performing tactical operations and ensuring that the operation meets the demands of the fire or emergency scenario.

Monitoring flow rates helps prevent potential issues such as running out of water or over-pressurizing hoses, which could lead to equipment failure or safety risks. In contrast, controlling water temperature, measuring discharge pressure, or indicating water levels in the tank serve different purposes that are not directly related to flow measurement, making the selected answer the most suitable choice.
