Automata’s Bubbler is designed to facilitate water level measurement without the need to immerse instruments into the water. The end of the tubing is placed at a known depth below the water surface that is to be measured. The pressure required to force bubbles out of the end of the tube equals the hydrostatic head of water above the end of the tube. It is easy to use and only the tubing is submerged. The device can be connected to Automata’s MINI-SAT™ or MINI-SS Field Station and the user can view the data either by Internet or personal computer depending on the telemetry of each field station.
