Pressure as well as temperature are static parameters, where as flow is dynamic parameter. Pressure and temperature units does not contain any velocity or acceleration parameters, where as units for flow does contain velocity parameters. Pressure creates static force, where as flow creates work done. Energy is transfered by flow and not by pressure alone. For example high pressure oil must FLOW in or out of hydraulic cylinder to do some work. If cylinder does not move, no oil flows and no work is done! So, when ever we want to measure efficiency of hydraulic power pack, we must be able to measure flow of oil at high pressure. Measuring pressure alone does not give us all the true condition of power pack.

Approximately 45% of machine failures can be Predicted just by monitoring the Trend of 2 operating parameters on the machine: Vibration and temperature..
