I am measuring the level of the catalyst in regen with d/p transmitter,the distance between taps is 498 " the density of lower section 25#/ft^3 and upper 3#/ft^3
What is the cal range " WC? It's continuous purge.

Best practice is to use LT range which gives high cat level at 80% (using actual cat density). If the entire range is used (including long dilute phase) the transmitter will be insensitive.
