Instrumentation Technology

Alright. I understand. I'd suggest Instrumentation and Control engineering. It has better placements and scope for higher studies as it's a developing field which is getting more and more prominent in the practical world. However, you really need to work hard if you take ICE. All the best :)

NIT-Trichy would be best for ICE.

B.Tech Instrumentation Engineering is a niche branch of engineering with comparatively lesser scope but competition also is very less because limited Engineering colleges offer this course. Most of the jobs after degree will be in manufacturing sector in various kind of industry. Chemical and Petroleum manufacturing companies employs maximum Instrumentation engineers. It is good branch to opt.
All the best.

Instrumentation is a niche branch with limited career opportunities. Role of instrumentation engineering can be filled by electronics, electrical and mechanical engineering also. ECE has wider scope and career opportunities. ECE grads are employed by all type of industries but majority in electronics, telecom, IT and ITES industries. ECE grads are preferred for IT infrastructure management and support roles also. ECE grads have opportunities in comparison to Instrumentation engineers.

Join a power plant company as a commissioning engineer. You'll have heaps of challenge, plenty of problem solving and trouble shooting, loads to still learn, get to see the world, earn good money, enjoy some small team independence and plenty of prospects to get to know the business and later rise in the organisation.
There are also plenty of opportunities to change your job later. For example, lots of banks, pension funds, etc. own power plants these days with no clue how to operate or maintain them. Good and experienced personnel are in short supply.
Possible initial employers are Siemens, Alstom, GE, Mitsubishi.

If you are a B.Tech holder or and you have knowledge about this field then you can join faculty for instrumentation faculty.
