Internal Power
Internal power is supplied to the FlowHawk flow monitor by an
internal 12-volt battery pack (p/n 8000-0043). The battery pack
resides within the FlowHawk enclosure and powers monitor
operations. An on-board backup battery sustains the monitor
memory (RAM).
FlowHawk 12-volt battery
The power regulator, built into the dome assembly that covers and
protects the processor board, is critical to intrinsically safe
operation. It regulates the voltage supplied from the internal IS
battery pack to the FlowHawk, ensuring that the monitor always
operates within its IS certification requirements. It also includes
replaceable fuses and current-limiting components that will limit
and/or interrupt power if a fault condition occurs.
