Compact Constant Flow (CF) Bubbler

The Compact Constant Flow Bubbler (Part #56-0133-25-1S), 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. An optional external desiccant is available. The Compact Constant Flow Bubbler’s built-in precision Accubar® Pressure Sensor meets the high accuracy requirements for stream gaging & 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 and RS232 and SDI-12 ports for communications and maintenance. The front panel includes a display and keypad. It also supports MODBUS.
