Level Measurement Methods Quiz

What type of device allows measurement of head pressure without contact with the process fluid?

Which device is used to measure the buoyancy to determine the level in a tank?

What can be used to measure solids in a vessel to determine their level?

What is the term for the common boundary between water and gasoline in a mixture that has settled?

Which devices measure distance using electromagnetic waves?

What is an example of direct level measurement?

What is an example of indirect level measurement?

Which principle states that an object immersed in a fluid is buoyed by a force equal to the weight of the displaced fluid?

If the mass of a liquid remains constant and its density decreases, what happens to the level of the liquid in a tank?

Is the gauge glass (sightglass) considered one of the oldest indirect level measurement devices still in use?

Bubbler is a special head pressure method that measures liquid pressure without contact using a gas stream
Displacer is a sealed cylindrical tube used to measure buoyancy and determine level
Displacer can measure the level of solids in a vessel
Interface is the common boundary between two liquids
Ultrasonic devices measure distance using sound waves bounced off a liquid surface
Sightglass and dip stick are examples of direct level measurement
Head pressure is an example of indirect level measurement
Archimedes' principle states that an object immersed in a fluid experiences an upward force equal to the weight of the displaced fluid
Level, temperature, density, and volume are correlated. Changes in one affect the others.
If mass remains constant and density decreases, level increases.
If mass remains constant and density decreases, temperature increases.
If mass remains constant and density decreases, head pressure decreases.
Sightglass is a direct level measurement device and has been used for a long time.
