Single Orifice Constant Flow Bubble Gauge/Recorder

The Accubar® Constant Flow (CF) Bubble Gage is a self-contained, precision device to measure water levels & water temperature, consisting of a pump, tank, manifold, control board, display/keypad & enclosure.
The CF 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 &/or backup (redundant) data recording and RS232 & SDI-12 ports for communications & maintenance. Also supports MODBUS.
