Getting Started
Power and Signal Connections
Power can be supplied to your meter through either the power jack or the
multi-pin connector on top of your device.
✓
Meter power jacks require a 9–24 Vdc power supply with a 2.1
mm female positive center plug capable of supplying at least
50 mA. 4–20 mA analog signal outputs require at least 12 Vdc
and 100 mA, and 0–10 Vdc outputs require at least 12 Vdc.

Note:
The above pinout is applicable to all flow meters with the Mini-DIN
connector. The availability of different output signals depends on the options
ordered. Optional configurations are noted on the unit’s calibration sheet.

Caution:
Do not connect power to pins 1 through 6,
as permanent damage can occur.
It is common to mistake Pin 2 (labeled 5.12 Vdc Output) as the
standard 0–5 Vdc analog output signal. Pin 2 is normally a
constant 5.12 Vdc that reflects the system bus voltage.

DB9 and DB15 pinouts, see
