Question
What is the working principal of Mass flow transmitter?
 Question Submitted By :: Instrumentation
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
It is a combination of a flow meter and a density meter
combined either as one unit or two separate instruments and
the final mass flow calculation gets done at a remote
location. Good example of a all in one unit is the Coriolis
meter. You can read the flow, the density or the mass flow
directly from it and configure its output to give you
whatever you need to be displayed on your supervisory system.
The principle it works on is vibration tubes. The variance
in vibration is a direct and proportional result due to the
variance in flow. So the frequency of the vibration is
monitored and converted into the output signal obviously
with some calculations inside to get the density and mass
flow as well.
Good luck
