Power
The FlowShark flow monitor can be powered internally or
externally. Both options are described below.
Internal Power
ADS offers several models of FlowSharks powered by internal
batteries: AG, AL, AS, AG-M, BL, BG, and CG-1 (see note below).
Power is supplied by two 12-volt alkaline battery packs (ADS p/n
5000-0557) mounted at the bottom of the chassis. These battery
packs provide the power for operating the monitor, running the
communication hardware, and sustaining the monitor memory
(RAM) through the power supply on the processor board. The
monitor measures the battery voltages, and Profile provides a user-
defined setting to ensure the monitor signals a warning when the
available power is low.
Note: The externally-powered FlowShark CG-1 includes
the 12-volt battery pack as an available alternative to
external power.
The two battery packs function in parallel to power all operations
for A series, B series (except BG), and CG-1 monitors. For BG
monitors, one battery pack provides power for monitor operations
and the other provides power to the wireless modem in the monitor.
