INSTRUMENTATION EXAM 2 EXAM
WITH CORRECT QUESTIONS AND
ANSWERS 2025
Level can be defined as the ______ of a material's surface distance from a
zero reference - CORRECT-ANSWERSHeight
Interface level - CORRECT-ANSWERSThe measurement of the process
variable (level).
A place where two materials meet; can be between two liquids, a liquid and a
slurry, or a liquid and foam
The common boundary, or plane, between two immiscible (i.e., incapable of
mixing) liquids
The hydrostatic head pressure exerted by 36 inches of water is equal to
_______ inches of water column pressure - CORRECT-ANSWERS36 in. w.c.
A bubbler is a special kind of head pressure measuring method that allows us
to measure the head pressure of a liquid without the pressure sensor coming
in contact with the process fluid - CORRECT-ANSWERSTrue
D/P transmitter - CORRECT-ANSWERSMeasures the difference between
total pressure and vapor space pressure
, A device that responds to the pressure created by the primary device and
then converts the pressure signal into standard output signal that can
represent either differential pressure or flow rate.
If the mass remains constant and the density of a liquid in a tank decreases
the level of the liquid in the tank will - CORRECT-ANSWERSIncreases
When the Volume of a liquid in a tank decreases the level of the liquid in the
tank will - CORRECT-ANSWERSDecrease
To calculate the Reynolds number which of the following variables is not
needed to perform the calculation - CORRECT-ANSWERSLaminar flow
number
You will need:
Inside diameter of the pipe
Viscosity of the fluid
Density of the fluid
Velocity of the fluid
When a flowing fluid possesses a Reynolds number that is greater than 4000
it is considered to be laminar - CORRECT-ANSWERSFalse
The temperature of the flowing fluid must be considered when measuring
______ flow rates - CORRECT-ANSWERSMass
