What is used to measure system pressure at one or more points?

A pressure gauge is an instrument specifically designed to measure the pressure within a system at one or more points. It provides a clear reading of how much pressure is present, which is crucial for ensuring the proper operation of various equipment, including those used in herbicide application in right-of-way management.

Using a pressure gauge helps operators monitor system performance, maintain efficiency, and prevent issues related to over or under pressure, which can affect the effectiveness of the application process. In contrast, nozzles are primarily responsible for dispersing the herbicide, filters help keep the system clean from debris, and pumps are designed to move the fluid through the system, but none of these directly measure the pressure within the system. Each of these components plays an integral role in the overall system, but the pressure gauge is the specific tool needed for pressure measurement.
