7.10 Device-Specific Commands
A single device specific command is implemented, Clear Totals.
7.10.1 Command 181 (0xB5): Clear Totals
The Clear Totals command resets the accrued values for volume, mass and energy that have flowed through the
meter. The timer associated with the trio of totals is also set back to zero. All totalizers resume aggregating flow
immediately after the command is executed.
The effect of this command is equivalent to Command 52, Set Variable Zero, if the command 52 device variable
specified is a Totals variable, it will clear all totals.
Note:
The function is global.
Sentinel LNG
can be configured to use individual transducer pairs, or channels, to
measure flow in separate pipes. The clear totals command will reset the volume, mass, energy and time for
every channel.
