Instrumentation means Take example of Washing at home
Instrumentation is Getting a manual Washing m/c, You have
to load cloth and wait for water to fill then after alarm

intrumental not Toally by human, But if go for fully
automatic m/c Then you automated your washing operation I
think its very clear and simple way to understand
