What is Instrumentation Engineering?
It is the branch of engineering which deals with the measurement, monitoring, display, etc. of the several of energy exchanges which takes place during process operations. "In short Instrumentation is the study of Instrument."
Instrument:
Instrument is a device which is used to measure, monitor, display, etc. of a process variable.
So what are the process variables?
The process variables are:

Instrument:
Instrument is a device which is used to measure, monitor, display, etc. of a process variable.
So what are the process variables?
The process variables are:
- Flow
- Pressure
- Temperature
- Level
- Quality i.e. %O2, CO2, PH, etc.
Define all the process variables and state their unit of measurement?
Flow: Any fluid or liquid moving from one place to another is called flow and it is defined as volume per unit of time at specified temperature and pressure conditions, generally measured by positive-displacement or rate meters.
Units: kg/hr, liter/minute, gallon/minute, m3/hr, Nm3/hr. (Gases)
Pressure: It is defined as force per unit area. P=F/A
Units: bar, Pascal, kg/cm2, lb/in2
Level: The height of the water column, liquid, and powder, etc. at the desired measurement of height between minimum level points to maximum level point is called level. The measurement principle is head pressure method.
Units: meters, mm, cm, percentage.
Temperature: It is the degree of hotness or coldness of a body is called temperature.
Units: Degree Centigrade, Degree Fahrenheit, Degree Kelvin, Degree Rankin
Quality: It deals with analysis. (pH, %CO2, %O2, Conductivity, Viscosity
