Data Interpretation:
Each pulse from the Minol flowmeter represents one US gallon. The data recorded in the logger will be the number of counts
(pulses) per logging interval. For conversion to other units, the data must be exported from HOBO software (refer to the software
documentation for details on exporting or sharing data).
Connect either the black or the white CABLE-2.5-STEREO wire (red wire not used) to
either of the two wires from the flowmeter (polarity not important) and then connect
remaining two wires to each other. Use appropriate termination for connections.
