8.6 Read totalizer and inventory values
ProLink III View the desired variable on the main screen under Process Variables .
Overview
Totalizers keep track of the total amount of mass or volume measured by the transmitter
since the last totalizer reset. Inventories keep track of the total amount of mass or volume
measured by the transmitter since the last inventory reset.
Tip
You can use the inventories to keep a running total of mass or volume across multiple totalizer
resets.
8.7 Start and stop totalizers and inventories
ProLink III Device Tools > Totalizer Control > Totalizer and Inventories > Start All Totals
Device Tools > Totalizer Control > Totalizer and Inventories > Stop All Totals
Overview
When you start a totalizer, it tracks process measurement. In a typical application, its value
increases with flow. When you stop a totalizer, it stops tracking process measurement and
its value does not change with flow. Inventories are started and stopped automatically,
when totalizers are started and stopped.
Important
Totalizers and inventories are started or stopped as a group. When you start any totalizer, all other
totalizers and all inventories are started simultaneously.When you stop any totalizer, all other
totalizers and all inventories are stopped simultaneously. You cannot start or stop inventories
directly.
