TOTALIZER
CONFIGURATION
The totalizer tracks total flow in the process line. You can start, stop, or
reset the totalizer as well as configure it to present the data specific to
your application on the LOI display.
Totalizer Display On the LOI, the Totalizer Display allows you to choose the desired
format for indicating the totalized values. You may choose either
forward-reverse or net-gross for displaying totalized values.
On the HART Communicator, Gross, Net, and Reverse values are
always available.
Forward-Reverse
Forward-Reverse shows both the forward and reverse totalized values,
updating continuously. You must choose reverse flow enable to allow
totalizing in the reverse direction.
These values cannot be reset by using the totalizer reset button. Reset
them by doing one of the following:
• Change the pulse scaling.
• Change the tube size.
• Change the units.
• Power down a transmitter that is not equipped with the
non-volatile totalizer option.
Net-Gross
Net-Gross shows both net and gross total values. It updates continuously.
The net value can be reset by the operator. The gross value cannot be reset
by using the
→ button. Reset it indirectly by doing one of the following:
• Change the pulse scaling.
• Change the tube size.
• Change the units.
• Power down a transmitter that is not equipped with the
non-volatile totalizer option.
To prevent an operator from accidentally resetting the gross value, the
Software Protect jumper on the electronics board should be in the ON
position. This action does not block the functions of the
E ← and →
buttons for starting and stopping or reading and resetting the totals.
Example
If you had a batch-type process, you would use the net value to measure
each batch and then have the operator reset it. In addition, the gross
value would keep track of a period of production (e.g., eight hour shift,
day, week, month). The gross value could be reset by cycling power to
the unit (if not equipped with a backed totalizer battery) or changing
one of the parameters described above.
