Study Notes
Level Measurement Methods
- 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.
