Lets see now...
Level transmitter to output 4 to 20mA depending on level
(ie: 4 to 20mA = 0 to 100% full)
PLC analog input to read in 4 to 20mA; also scale this to the same as the level transmitter.
Now a question for you; why would you use 4 to 20mA instead of 0 to 20mA?

Steve

Dear Curtis you should start by taking the transmitter and sticking it up your ***. HAHA.
