Level and Flow Measurement Quiz

A float-type level sensor works on the principle of:

• Conductivity

• Buoyancy

• Capacitance

• Radiation

The main limitation of a simple float level measurement system is:

• High cost

• Cannot work with conductive liquids

• Sensitivity to turbulence

• Requires power supply

Capacitance level sensors work on the principle of change in:

• Inductance

• Dielectric constant

• Resistance

• Pressure

A capacitance level sensor is best suited for measuring:

• Non-conductive liquids

• Metallic solids

• Gas flow

• High-pressure steam

Radiation-based level measurement is typically used in:

• Food processing

• Nuclear power plants

• Transparent liquids

• Open tanks

Gamma-ray level measurement is preferred for:

• Hazardous and high-temperature environments

• Open water tanks

• Low-cost applications

• Mechanical float-based systems

Ultrasonic level sensors work by measuring the:

• Change in capacitance

• Reflection time of sound waves

• Weight of the liquid

• Change in electrical resistance

Which of the following factors can affect the accuracy of an ultrasonic level sensor?

• Dielectric constant of liquid

• Electrical conductivity of fluid

• Temperature and humidity

• Color of liquid

Electromagnetic flow meters work based on:

• Bernoulli's theorem

• Faraday's law of electromagnetic induction

• Doppler Effect

• Pascal's law

Which type of fluid is best suited for electromagnetic flow meters?

• Oil-based fluids

• Non-conductive fluids
