The Bubbler is a radio licence-exempt wireless liquid level monitoring system for up to four remote dams/bores/rivers/tanks at separate locations within a 5 km range.
Levels are gauged by monitoring pressure in a 6 mm pneumatic tube pulsed from a miniature air source and telemetering the value to a central receiver where depth is displayed in cm.
The tank transmitter can be solar powered at sites and the 6 mm air line means all electronics are in the box with no wires down the bore hole or in the tank.
The receiver has user adjustable independent hi/lo level alarms for each monitoring point. These eight separate setpoints are linked to a common internal piezo alarm and are individually mutable via four isolation switches, one for each bore/dam.
A relay output is provided for a phone dialler if alarms to mobile phones are required.
A SCADA version of the receiver has four separate relay outputs, one for each tank. In this format the receiver is suitable for supervisory control, with the independent relay outputs capable of maintaining tank level within the hi/lo setpoints for each site.
