What is typically used to measure hydraulic pressure within a system?

The measurement of hydraulic pressure within a system is typically performed using a pressure gauge. A pressure gauge is specifically designed to display the pressure of a fluid within a hydraulic system, allowing operators to monitor and maintain the system's performance. These devices can be analog or digital and are essential for ensuring that the pressure remains within safe operating limits, which is crucial for the safe operation of hydraulic machinery.

In contrast, a flow meter is used to measure the flow rate of a fluid, not its pressure. A thermometer measures temperature, which is not directly related to pressure measurements in hydraulic systems. A viscometer, on the other hand, is utilized to determine the viscosity of a fluid, which is important in fluid dynamics but does not provide information about hydraulic pressure. Therefore, the appropriate instrument for measuring hydraulic pressure is indeed the pressure gauge.
