We are updating instrumentation on a steam turbine condenser which originally used a displacement level transmitter. We have purchased an electronic DP transmitter to replace the displacement type. At first glance the changeover looks easy, simply by connecting the'H' input to the measured variable and the 'L' input to the condenser shell, thereby providing a diff. measurment. But, I am afraid the 'L' input will eventually fill with condensate because of the tremendously humid environment in the condenser.
Second thought is to fill one leg with condensate on purpose as a reference and setting the TX up as reverse acting, but the reference leg would evaporate out during down times....
Any suggestions would be appreciated.
