Capp: A bubbler is pretty simple. You put a tube in liquid and have a pressurized gas push bubbles out.
Capp: As the level in the tank changes, the pressure needed to push the gas out changes. It's good for dirty systems. The sensor never comes in contact with the liquid.
Capp: From the technician point of view, having a sewage sensor that never comes in contact with the liquid is a good thing. It means when we calibrate it, we never have to come in contact with the liquid.
