What is difference between direct sensing and indirect sensing of level
Answers
Answer:
Direct measurement' refers to measuring exactly the thing that you are looking to measure, while 'indirect measurement' means that you're measuring something by measuring something else.
Explanation:
For example of direct measurement is weight, distance, and so on. Therefore, if I want to measure how long a piece of wood, I just measure it.
However, let say if I want to find out about something that is a little harder to measure like how quickly the wind is blowing. I may not be able to measure the wind's actual speed, but if I had a windmill, I could measure how much power the windmill is making. Then, using this information, I could work backwards to figure out how fast the wind must be. This would be an example where I have to measure something 'indirectly.'
