• The
Accubar® Constant Flow (CF) Bubble
Gage is anall-in-one, precision
device for measuring water levels. The
gage features a front panel, RS232 & SDI-12
ports to simplify setup, test, data communication & maintenance.
The gauge also has a built-in datalogger
for stand-alone operation or backup recording
of data.
• The Constant Flow Bubbler consists of a pump, tank, manifold, control
board, display/keypad & enclosure for the purpose of measuring water levels
using long-established bubble gage principles, all packaged within a single NEMA-4 enclosure.
