Vsan Electricals & Sensors Interview Questions and Answers

Flow meters are devices used to measure the flow rate of a fluid in a pipe or conduit.

• Differential pressure flow meters (e.g. Orifice plate, Venturi tube)

• Positive displacement flow meters (e.g. Piston, Gear, Turbine)

• Velocity flow meters (e.g. Electromagnetic, Ultrasonic)

• Mass flow meters (e.g. Coriolis, Thermal)

Level sensors are used to measure the level of liquids or solids in tanks or containers.

• Level sensors are commonly used in industries such as oil and gas, chemical, food and beverage, and water treatment.

• They can be used to monitor and control the level of liquids, powders, or granular materials.

• Different types of level sensors include ultrasonic, capacitance, radar, and float sensors.

• Level sensors help in preventing o...read more

Flow meters are devices used to measure the flow rate of a fluid in a pipe or channel.

• Differential pressure flow meters (e.g. Orifice plate, Venturi tube)

• Velocity flow meters (e.g. Turbine, Ultrasonic)

• Positive displacement flow meters (e.g. Piston, Oval gear)

• Mass flow meters (e.g. Coriolis, Thermal)

Flow sensors work on the principle of measuring the flow rate of a fluid by detecting the change in physical properties such as pressure, temperature, or velocity.

• Flow sensors can use different methods such as differential pressure, thermal, or ultrasonic to measure flow rate.

• Differential pressure flow sensors work by measuring the pressure drop across a restriction in the flow path.

• Thermal flow sensors measure the hea...read more
