An expansion valve in an improperly operating refrigerator system is shownbelow. The system is misoperating such that there is gas on both sides of theexpansion valve, not liquid as would be found on a properly operating system.What would a pressure gauge read on the low pressure side of the expansionvalve?
PROCESS INSTRUMENTATION AND CONTROL
Explain with a neat sketch the principle of Ultrasonic flow meter.
Three different types of thermocouples
generate different voltages when measuring
the samé temperature because:
Select one:
a. They generate the same voltage at the
same temperature.
b. The voltage generated should be
modified because of the use of the
amplifier.
c. They are made of different materials.
d. There are instrument errors.
