RECHARGING THE INTERNAL BATTERY

The Ultrasonic flow meter is supplied with a 12 Volt charger that plugs into the Mini-USB mating receptacle on the side of the Flow Meter.

Even though the same mating receptacle is also used for the Addresser communication cable, the Ultrasonic recognizes that the Charger is connected, and not the Addresser, and it begins recharging. The Charging light will be lit, and the Flow Meter will recharge the Lithium-ion battery in 3 to 4 hours. However, you must remove the Charger to operate. A fully charged Ultrasonic will run up to 10 hours continuously, providing a full days worth of data (or many days with intermittent

use). If the Ultrasonic is left inactive for 15 minutes, it will automatically power down.
