Answer / ahmed helmy
Q= Cv sqrt(delta P/G)
where:
Cv:Flow Coefficient
delta P:the difference between Inlet and outlet pressure
G: specific gravity
so from this equation, we find a relationship between flow (Q) and delta P

Answer / muslim
DP reading is small compare to actual flow so square root
will make the linear relation between Dp and actual
flow.also some time we have to consider the fluid density

The company where I am working, their is rosemount 5400 series radar type level transmitter, it is meant to show level of filled tank, but along with the level it is showing temperature also, so my question is how a onon-contact type radar type level transmitter can show temperature even if it does not have any contact with the fluid?
