External Power The H2OPro Flow Gauge can use an external power supply connected to the E-PWR and GND wire connections. The power supply should be between +4VDC and +24VDC. The external power can be used with or without the batteries installed. When the external power supply is used the batteries will not supply power, however they will power the system if the external power supply is disconnected or fails.
