What is the primary function of a Pitot gauge?

The primary function of a Pitot gauge is to determine flow rate. It achieves this by measuring the pressure of a fluid (either liquid or gas) as it flows. The Pitot gauge works on the principle of differential pressure, where it utilizes a static pressure port and a dynamic pressure port to capture the pressure difference generated by the flow. This information allows firefighters and other professionals to calculate the flow rate of water or other fluids in hoses and pipelines, which is crucial for efficient firefighting operations and ensuring that adequate water supply is available at the scene of a fire.

While measuring liquid volume, recording temperature, and assessing chemical concentration are important functions in various contexts, they are not the primary roles of a Pitot gauge. This device specifically focuses on the flow dynamics of fluids, making it an essential tool in understanding how much fluid can be delivered in response to firefighting needs.
