The Compact Constant Flow Bubbler (Part #56-0133-25-1ST), 50% smaller
than Sutron’s original Constant Flow Bubbler, is a self-contained, precision
device to measure water levels & temperature. It consists of a pump, tank,
manifold, control board, display/keypad & enclosure. The new Compact CF
Bubbler houses all components within a 10.5”x 8.5”x 7.5” polycarbonate
NEMA-4X enclosure.
The Compact Constant Flow Bubbler’s built-in precision Accubar® Pressure
Sensor meets the high accuracy requirements for stream gaging &
10.5”
monitoring of tidal/coastal areas, estuaries, groundwater & reservoirs.
The Bubbler includes a built-in datalogger for stand-alone operation
and/or backup (redundant) data recording, RS232 and SDI-12 ports for
communications and maintenance, and a desiccant kit. The front panel
includes a display and keypad. It also supports MODBUS.
