Does the brine density change? If so, the density change
will appear as a level error.

Has the transmitter been zeroed to correct for out-of-plumb
installation error?

What is a sealing diaphragm? An extended diaphragm on a
flange mounted transmitter?

A capillary connection between the diaphragm and the
transmitter? A capillary connection requires compensation
for fill fluid density and has an inherent temperature error.

What is the low side connection? dry leg? wet leg?
capillary and seal?

Is the level readout in the 'receiver' density compensated?

I have installed a RTD whose length is 2250mm(RTD stem length), but it's upper 200 -250mm is out of the reactor, and this upper 200mm stem is surrounded by atmospheric temp. And the lower portion i.e. 2000mm is in contact with the measuring fluid, then does the final measuring temp. Gonna change as the upper 200mm RTD stem is out of reactor?
