National Fertilizers Instrument Engineer Interview Questions and Answers

Various instruments work on different principles and technologies to measure and control physical quantities.

• Instruments like thermocouples, RTDs, and thermistors measure temperature based on the change in electrical resistance with temperature.

• Flow meters like orifice plates, venturi meters, and magnetic flow meters measure the flow rate of fluids based on the pressure drop across a constriction in the flow path.

Budgeting of instrumentation involves identifying the required instruments, estimating their costs, and allocating funds accordingly.

• Identify the required instruments for the project

• Estimate the cost of each instrument

• Allocate funds based on priority and availability

• Consider maintenance and replacement costs

• Regularly review and adjust the budget as needed

Flow meters are devices used to measure the flow rate of fluids or gases in a system.

• Differential pressure flow meters (e.g. orifice plate, venturi tube)

• Positive displacement flow meters (e.g. piston, gear, nutating disc)

• Velocity flow meters (e.g. turbine, vortex, electromagnetic)

• Mass flow meters (e.g. Coriolis, thermal, ultrasonic)

Types of level transmitters include ultrasonic, radar, capacitance, and differential pressure.

• Ultrasonic level transmitters use sound waves to measure the distance between the sensor and the liquid surface.

• Radar level transmitters use electromagnetic waves to determine the level of the liquid.

• Capacitance level transmitters measure the change in capacitance between two electrodes as the liquid level changes.

• Differential...read more
