1,why we use 4-20 ma output of all instrument qhy not use 0- 20, 2,what is the different between PLC & DCS. 3,how can we meaure maximum span of new flowmeter if not given any information.
4 12545how can we calibate ph meter. how can we calibrat conductivimeter how can we calibrat massflowmeter & it s working.

How to Calibrate Radar Level Transmitter in Field
Q1: Consider part of a control loop, which excludes the transmitter, consisting of a process, a controller and a control valve which may be represented by two dead times of 0.5 min each and three exponential lags of 0.8 min., 1.0 min. and 1.5 min. respectively. We wish to express this system as an overall first order plus dead time (FOPLD) model ie gain, time constant and process dead time. (We will see later that this is often done, to simplify controller tuning). For this exercise, gain is considered to be 1.0. (A) If the transmitter is a flow transmitter whose behaviour can be described by a dead time of 0.2 min. and an exponential lag of 0.5 min. in terms of the overall dead time and overall first order lag how can the system behaviour be approximated ? Overall dead time = Overall time constant = (B) If the transmitter is a temperature transmitter with a temperature sensor in a protecting well whose behaviour can be described by a dead time of 0.7 min. and an exponential lag of 15 min. how can the overall system behaviour be approximated now? Overall dead time = Overall time constant =

Hi i am aneesh, done btech in applied electronics & instrumentatiin. And then i took mba in finance & marketing.After that i got placement in finance co and worked there for 3.5 yrs.Now i wanted to come back to engineering job.But without engg experience, i may not able to find an opening.i have done a course related to flow meters and ite calibrations. Kindly suggest where should i try to get a job?
