Differential Pressure Flashcards
1
Q
Why is the low side of the pressure cell connected to the top of a pressurized vessel?
A
This cancels out the pressure that exists in a tank
2
Q
What is an advantage to using 2 transmitters over a single transmitter when measuring density?
A
Dual transmitter setup removes error due to changes in ambient temperature affecting the fluid in the seal legs
3
Q
What is an advantage of using a differential pressure regulator with a flow indicator?
A
1) Flow reading stays steady and accurate
2) Easier control
3) Good repeatability
4
Q
When using a vertical flow run chamber to determine fluid density, what is the purpose of the identically sized horizontal chamber?
A
To measure the differential pressure loss due to fluid flow
