For data of physics, "How is it measured ?" is important.
The data of electrical flow is used to define "ON or OFF". I use this method in Analysis of Type 2 of Sensor Data Analysis.
And "ON" is used as the flag to analyze the use of machine.
Temperture of machines are often related with the temperture of the environment. In the analysis, it is useful to devide into two causes, inside and outside of the machine.
Velocity data is the Differentiation Data. It could be changed into other information by the integration by time.
There are some types of the units of flow.
