I applied via Referral and was interviewed in Jul 2019. There were 3 interview rounds.
Flowmeters are devices used to measure the flow rate or quantity of a gas or liquid moving through a pipe.
There are several types of flowmeters including differential pressure, positive displacement, turbine, electromagnetic, ultrasonic, and vortex flowmeters.
Differential pressure flowmeters measure the pressure drop across a constriction in the pipe.
Positive displacement flowmeters measure the volume of fluid passing ...
Valves are devices that control the flow of fluids or gases through pipes or ducts.
Gate valve
Ball valve
Butterfly valve
Check valve
Globe valve
Needle valve
Diaphragm valve
Pressure relief valve
Ball valves have a spherical closure unit while gate valves have a wedge-shaped closure unit.
Ball valves are quick to open and close, while gate valves take longer.
Ball valves are better for controlling flow, while gate valves are better for on/off control.
Ball valves are commonly used in applications such as water supply, oil and gas, and chemical processing.
Gate valves are commonly used in applications such as irriga
Valve cavitation is the formation and collapse of vapor bubbles in a liquid due to pressure changes, while flashing is the sudden vaporization of a liquid when pressure is reduced.
Cavitation occurs when the pressure in a liquid drops below its vapor pressure, causing bubbles to form and then collapse violently when they reach a higher pressure area.
Flashing occurs when a liquid is suddenly exposed to a lower pressure e...
Electrical classification areas are designated areas where the presence of flammable gases, vapors, or dusts require special precautions.
Electrical equipment installed in these areas must be designed and tested to prevent ignition of the hazardous materials.
There are three main classifications: Class I for flammable gases and vapors, Class II for combustible dusts, and Class III for ignitable fibers and flyings.
Each cl...
Flowmeters should be selected based on the type of fluid, flow rate, and accuracy requirements.
Identify the type of fluid being measured
Determine the flow rate range
Consider the accuracy requirements
Choose the appropriate flowmeter technology (e.g. differential pressure, magnetic, ultrasonic, etc.)
Ensure compatibility with the process conditions (e.g. temperature, pressure, viscosity, etc.)
Pressure sensors work on the principle of converting physical pressure into an electrical signal.
Pressure sensors measure the pressure of gases or liquids
They can be based on different technologies such as piezoresistive, capacitive, or optical
The output signal can be analog or digital
Applications include automotive, medical, and industrial fields
