continiously because due to agitator tank surface level
will vary every time.

Just increase the damping on the radar's 4 to 20mA output.
This should stabilize the output, even if the local display
still jumps around.
In the DCS there is also damping that will help with the
input from the radar.
You will never be able to measure an "exact" level in a
turbulent application like this so the best you can do is to
use the average over a period of time and that is what the
damping does. It smooths out the ripples in the output by
taking samples of the level measurement and then give a
average output.
Good luck
