Note: Only the 5600-0131-3 and 56-0131-50-1 support Quadrature and only the 5600-0131-4 and
56-0131-50-2 support analog out.
5600-0131-5 supports SDI-12 output only.
The ACCUBUBBLE needs two power connections. The first is to a 12 VDC 3 A power source to power the
pump. The second is to power the pressure sensor. It is recommended that the pressure sensor power be in
common with the device reading the sensor. If the sensor is being read by an SDI-12 data recorder, then the
sensor power would come from the SDI-12 data recorder (SDI-12 defines a three wire connection of data,
12V, and Ground). The SDI-12 12V should be used for the internal SDI-12 sensor, but should NOT be used
to power the pump. The 12 VDC power supply for the pump needs to share a common ground with the SDI-
12 data recorder collecting data from the AccuBubble.
