Measuring liquid level using a differential pressure transmitter

[MolsonWeiser]

whicked , we're doing a huge project (cascade), we have 3 , 50 gallon tanks , 2 lever valves , 2 pumps , 1 drive , 3 bubbler systems (which includes the rotameters , DP cells (unfortunetly we dont have the "smarts" since they are all taken by other students , pressure regulators and a whole lot more goodies! I'll try to get a vid up when we're done!

how does the DP transmitter convert the pressure into an actual level. I.E. inches or % full etc.

@istoleyourpie Evil Black Magic, that's how!

how can you sure there are no bubbles escaping from the dig tube into the tank of water ?

The air does indeed bubble into the tank, through the water. There isn't much air flow -- just a few bubbles per second.
