field instrumentation interview questions and answer

The differential pressure measured has nonlinear relation with flow through the pipeline. Differential pressure developed by a venturi, orifice plate, pitot tube, or any other acceleration-based flow element is proportional to the square of the flow rate. The square root extractor is used to convert the measured differential pressure into the flow rate

The following steps are to be taken which calibrating: 1. Adjust zero of the Tx’r. 2. Static pressure test: Give equal pressure on both sides of the transmitter. Zero should not shift. If it is shifting carry out static alignment. 3. Vacuum test: Apply equal vacuum to both the sides. The zero should not shift. 4. Calibration Procedure: * Give 20 psi air or 24V DC supply to the transmitter

* Vent the L.P. side to atmosphere. * Connect the output of the Instrument to a standard test gauge or Multimeter and adjust zero. 5. Apply required pressure to high-pressure side of the transmitter and adjust the span. 6. Adjust zero again if necessary

Pressure gauge: This is the simplest method, for pressure gauge, is located at the zero level of the liquid in the vessel. Any rise in level causes an increase of pressure which can be measured by a gauge

Purge system: In this method, a pipeline is installed vertically with the level open and zero. The other end of the tube is connected to a regulated air supply and to a pressure gauge. To perform a level measurement, the air supply is adjusted so that the pressure is slightly higher than the pressure due to the height of the liquid. This is achieved by regulating the air pressure until bubbles are seen in the cabin leaving the open end of the pipe

Differential pressure meter: Connections are made at the vessel top and bottom and to the two columns of the D.P. meter. The top connection is made to the L.P. column of the transmitter and the bottom to H.P. column of the transmitter. The difference in pressure in the vessel is balanced out since it is fed to both the column of the meter. The difference in pressure deducted by the meter will be due only to the changing, level of the liquid

Try not to use an example where you created the pressure yourself, by waiting too long to start something, or by handling a task irresponsibly at the beginning. For example, working under pressure to meet a customer’s deadline could be a good example, but not if you had waited too long to start the project

“Pressure is actually a catalyst to my work. When there is an imperative deadline, I refocus my energy into my work which in fact, has helped me to produce some of my best works. (Give examples) I guess you can say I thrive under pressure.”

If you are being asked this question from your employer then you can explain your experience. Tell the employer what responsibilities you were performing during your job. You can tell what programs you developed and what modules you worked on. What were your achievements regarding different programs
