Are you an engineering graduate in industrial instrumentation? Do you have excellent problem solving ability? Are you capable enough to work both in software or hardware sectors? Then follow us on www.wisdomjobs.com and trace your field. Industrial instrumentation is art and science of measurement and control of process of variables within a production or manufacturing area. Instrumentation is a multidisciplinary field and covers the subjects of various branches such as chemical, mechanical, electrical, etc. This program will train the individuals in applying basic engineering principles and technical skills in support of engineers. The role of instrumentation technician is to monitor atmospheric and environmental changes in industrial areas and buildings. You have a wide scope in aeronautics, space science; also can fit in both hardware and software sectors. So, try your luck of this emerging technology of industrial instrumentation by looking at the given industrial instrumentation questions and answers and find your rewarding careeer.
Question 1. What Are The Process Variable?
Answer :
The process Variable are:
Question 2. Define All The Process Variable And State Their Unit Of Measurement?
Answer :
Question 3. What Are The Primary Elements Usedfor Flow Measurement?
Answer :
The primary elements used for flow measurement are:
Question 4. What Are The Different Types Of Orifice Plates And State Their Uses?
Answer :
The different types of orifice plates are:
CONCENTRIC: The concentric orifice plate is used for ideal liquid as well as gases and steam service. This orifice as a hole in concentric and hence known as concentric orifice.
Eccentric & Segmental: The eccentric orifice plate has a hole eccentric. The use this is made in viscous and sherry flow measurement.
The segmental orifice place has the hole in the form segment of a circle. This is used for colloidal and sherry flow measurement.
Question 5. How Do You Identify An Orifice In The Pipe Line?
Answer :
An orifice tab is welded on the orifice plate which extends our of the line giving an indication of the orifice plate.
Question 6. Why Is The Orifice Tab Provided?
Answer :
The orifice tab is provided due to the following reasons:
Question 7. What Is Bernoulli’s Theoram And Where It Is Applicable?
Answer :
Bernoulli’s theoram states the “total energy of a liquid flowing from one point to another remains constant.” It is applicable for non compressible liquids.
Question 8. How Do You Identify The H. P. Side Or Inlet Of An Orifice Plate In Line?
Answer :
The marking is always done H. P. side of the orifice tab which gives an indication of the H.P.side.
Question 9. How Do You Calibrate A D. P. Transmitter?
Answer :
The following steps are to be taken which claribrating :
Calibration Procedure:
Question 10. What Is The Seal Liquid Used For Filling Impulse Lines On Crude And Viscous Liquid?
Answer :
Glycol.
Answer :
Liquid lines: On liquid lines the transmitter is mounted below the orifice plate. Since liquids have a property of self draining.
Gas Service: On gas service the transmitter is mounted above the orifice plate because Gases have a property of self venting and secondly condenlate formation.
Steam Service: On steam service the transmitter is mounted below the orifice plate with condenlate pots. The pots should be at the same level.
Question 12. An Operator Tells You That Flow Indication Is More? How Would You Start Checking?
Answer :
Question 13. How Do You Do A Zero Check On A D.p. Transmitter?
Answer :
Close one of the valve either H.P. or L.P. open the equalizing valve. The O/P should read zero.
Question 14. How Would You Do Glycol Filling Or Fill Seal Liquids In Seal Pots 7 Draw And Explain?
Answer :
The procedure for glycol filling is :
Question 15. How Do You Calculate New Factor From New Range Using Old Factor And Old Range?
Answer :
New Factor = _!New Range Old Factor = _IOld Range Flow = K_!Range
Q = Factor X Unit Flow
New Factor = Old Factor I _IOld Range X _/New Range.
Question 16. How Will You Vent Air In The D.p. Cell? What If Seal Pots Are Used?
Answer :
Question 17. Why Is Flow Measured In Square Root?
Answer :
