Answer / sam

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

Answer / jayesh

there are sensors available which allows you to select the
nature of fluid like weather it is turbulent of steady so
according to that it adds the damping factor to it and
gives you out put

Please any one can explain how to calibrate transmitter (smart) online with out remove from the container suppose it is interface level or static pressure level measurement we dont want to remove transmitter from the container mean it is running plant please give me detail. thankx brothers

Hi buddies! my name is sachin and i am working as a electrical and instrumentation engineer in a paper plant. right now i am facing a problem and if someone could help me it will be an immense pleasure to me. i am using AC 800M to synchronise DCS500 drives on paper machine and rewinder.communication is on PROFIBUS and we are using NPBA-01 module to link profibus to DC drives.But these days two of these drives are showing a error named FIELDBUS COMM.TIMED OUT and the drives get tripped.I have changed the NPBA module and PROFIBUS cable.So if anyone can do please help me out with this problem.I'll be highly grateful.
