Boiler Drum Level Measurement

I have used Magnetrol Eclipse guided radar level transmitters directly mounted on Boiler steam drum and one DP transmitter.

As I increase the load on boiler both radars start drifting away from DP transmitter. As soon as we have MFT all three become close to each other. Is there thing I am missing here?
 
You will need to density compensate the DP transmitter. As you increase load, the density of the water will drop and the level will rise without a change in dp.
