An interesting variation on this theme of direct hydrostatic pressure measurement is the use of a purge gas to measure
One of the oldest and simplest methods of level measurement is called the air bubbler, air purge, or dip tube.
In the bubble type level system, liquid level is determined by measuring the pressure required to force a gas into
Bubbler Level Measurement Animation shows the working principle of bubbler level sensor. Working Principle: A fixed constant air supply will
