Which tool is commonly used to measure water pressure?

The commonly used tool to measure water pressure is the pressure gauge. It functions by providing a direct reading of pressure in a system, usually in pounds per square inch (PSI) or in bar. Pressure gauges are specifically designed for this purpose and can be found in various applications, from residential plumbing to industrial systems. They help plumbers assess whether water pressure is within an acceptable range for safety and performance, allowing for necessary adjustments or repairs to ensure efficient system operation.

While other tools like flow meters measure the flow rate of water and manometers can measure pressure as well, they serve different primary functions. Flow meters track the volume of water passing through a point in a given time, whereas manometers are often used in laboratory settings or for specific applications where greater precision in measuring very low pressures is required. Water level indicators, on the other hand, measure the height of water in a tank rather than the pressure of the water system. This highlights the suitability of the pressure gauge as the appropriate tool for measuring water pressure.
