Bubbler Level Measurement Animation shows the working principle of bubbler level sensor.
Working Principle:
A fixed constant air supply will be given at the inlet (min 10psi). When there is no level in the tank then total air passed to atmosphere through pipe in the tank. When the level in tank increases means the proportional back pressure increases and the increased back pressure is proportional to level in tank.
When tank level is more then back pressure will increases. With the use a electronic transmitters (like pressure transmitters) we can convert the back pressure signal into 4-20mA level signal.

Hi Bharadwaj,
All the contents are really good and helps to refresh the principles. Additionally can you also add the applications and usage of specific measurements in field. Just an idea.
Eg: Magnetic Flow meters, Can be used only in Conductive fluids.
Sure, i will do my best. Also if any one interested to share their knowledge/data, plz send the information to [email protected]
Thanks
Sir, Parallely keep on posting related to PLC, DCS, MODBUS COMMUNICATION etc.
Plz can any one tell how to calibrate LL pressure switch and HH pressure switch
awesome!! thanks for introducing the basics..
so kind of you
Great knowledge sharing..
Much needed..
Thank you very much..
