Badger Meter ER-500 - Power Connections

Power Connections
The ER-500 monitor has two power supply options. The first power supply is an internal lithium 3.6V DC D size cell that powers
the monitor for about six years when no outputs are used. The monitor can also be powered by a 4…20 mA current loop.
See Figure 4. If the current loop is used, a sensing circuit within the monitor detects the presence of the current loop and
automatically disconnects the battery from the circuit.
