Power Modes

To keep power consumption to a minimum, especially for remote sites, the flow computer can run
in two different power modes: Low Power Mode (4 or 8 MHz CPU clock speed) or Standard Power
Mode (60 MHz CPU clock speed).

Low Power Mode

The flow computer normally runs in low power mode for typical metering applications. The radio
Power Control function (configurable in FBxConnect) switches the flow computer into standard
power mode at specified times when serial communications are required, then it reverts to low
power mode when the communication period is over. A serial connection to a remote 4088B MVT
can occur in low power mode.
