Totalizer Function
A Flow Totalizer is available as part of the Math Algorithm option. This calculates
and displays the total flow volume being measured by Input 1. Alternatively, it can
be applied to either Input Algorithm 1 or Input Algorithm 2 to totalize the
compensated flow rate being calculated by the algorithm.
The totalizer displays the current totalized flow value (up to seven digits
maximum). Seven scaling factors are available (from one to one million). The
desired scaling factor is applied to the calculated value to extend the maximum total
flow range that can be displayed.
Five integration rates are available to match the totalizer rate to the rate of flow
being measured. The rates are:
Engineering units (EU) per second
EU per minute
EU per hour
EU per day
Millions of units per day
The totalizer value is stored in nonvolatile memory once every eight hours. If power
is lost while the totalizer is in operation, the current value of the totalizer will be lost.
When power is restored, the totalizer will start operation for the last value stored in
nonvolatile memory. The

The totalizer can be reset from the keyboard whenever desired. The totalizer should
always be reset to initialize the counters whenever it is enabled, otherwise, the " "

Refer to Section 3 – Configuration, Set Up group ALGORTHM, function prompt
TOTALIZER to select an application, and the function prompts that follow
TOTALIZER to enter your scale factor and rate of integration.
Alarm on Totalizer Value
The alarm type configuration includes an Alarm on Totalizer value. This allows an
alarm setpoint value to be used to cause an alarm when exceeded. The alarm
setpoint represents the lowest four digits of the selected Totalizer Scale Factor and
has a range from 0 to 9999 x Totalizer Scale Factor.
Totalizer Reset Via Digital Input
The digital input type configuration includes a Reset Totalizer that resets the
accumulated totalizer value when the DI is closed.
