should I use Hydrostatic Pressure Transmitter for measurement of DENSITY of filled tank ? If YES then please explain how.
HPCL,
2 6851i am from instrument branch i want paper patern of mahagenco . any pevious years paper regarding my branch send me please . please.....
2053Sir,I am going to sit for IOCL written test exam. recently.Can anyone tell me the name of 'Objective type Question Book on Instrumentation Engineering ' which will help me. Pl. mail to bidyut_71@rediffmail.com / bidyut.saha2008@indiatimes.com / bidyut.saha09@yahoo.in
