Industry: General
In many industries, totalization is an important part in the
measurement and monitoring of flows to obtain the total flow
over a given time period. The flow, whether it involves gas or
liquid, can be determined using a variety of instruments such
as a pressure transmitter, a Magnetic Flow meter or a Coriolis
meter. No matter what instrument is doing the actual
measurement, this signal is typically sent to either a recorder,
controller, distributed control system or even a mechanical
totalizer to do the actual flow totalization. The most cost
effective method depends on the accuracy requirements, the
number of loops and what is to be done with the totalized
Honeywell has a number of solutions using standalone
recorders to do flow totalization, whether it requires Circular
Chart, Strip Chart or Video type recorders. Each recorder
The DR4500 Recorder offers expanded totalization capability
offers varying levels of showing and documenting the totalized
not available with the DR4300. This includes such features as:
values. The selection of which recorder to use depends on the
accuracy required, the values being totalized, the level of
documentation required, and preference of recorder type.
Circular Chart Recorders
The Honeywell Circular Chart recorders, such as the DR4300
and the DR4500 Truline , have the capability to do

The ability to measure in one set of units and to totalize in
different units such as having a flow in gals/hour but
totalize in acre-feet/day.

Totalization. The DR4300 provides a basic totalization
capability in a low cost circular chart recorder. It can totalize
one or two inputs from a flow device and display the totalized
value on the recorder’s vacuum fluorescent display for the
customer to view. The DR4300 can display up to 6 digits with a
configurable scale factor up to 100,000,000. The rate of
integration can be in time units of seconds, minutes, hours, day
or million units per day. The totalizer is capable of being reset
either from the front key panel or from a remote digital input.
The totalized value is stored in battery backed ram so it is not
lost in the event of a power failure. The DR4300 does not
provide print out of the totalized value on the chart.

An example of the chart is shown in Fig 2.

Strip Chart Recorders

Honeywell has a complete line up of Strip Chart Recorders
capable of providing totalization. These include the

DPR100C/D 100mm Strip Chart, the DPR180 180mm Strip
Chart, and the DPR250 250mm Strip Chart recorders. Each of

the recorders are designed to address specific customer needs
based on chart size, performance and price.
MA 1 Backup = Enabled
DPR100C/D Recorder
MA 1 Start = Continuous
The DPR100C/D Recorder provides totalization capability as
part of the Math Option. Totalization is included in Math Level 2
and allows the customer to totalize up to 6 different variables
independently. Math Level 4 provides additional flexibility to
sync the totalizers to a real time clock and to program the
recorder to print the totalized values at specific time intervals.
The DPR100 can totalize in seconds, minutes, hours, days and
million units per day. The totalizer can be controlled remotely
using the digital inputs. The Digital Inputs can be programmed
to Start, Stop or Reset the any individual Totalizer or it can be
programmed to Start, Stop or Reset all totalizers at the same
time. This is done in the Math function by programming the
Start, Stop and Reset functions with the appropriate digital
input. Up to 4 Digital Inputs can be ordered with the recorder.
The Right Arrow Key on the front of the recorder can also be
used to reset the totalizers individually or to reset all of them at
the same time.
The totalizer values can be displayed using the Down Arrow
Key on the front of the recorder and setting this to display Math
Results. The display can be set to scan through the math
results or to hold on a specific value. The recorder can display
a totalized value from -99999999 to 999999999.
To set the DPR100 recorder up to totalize, the totalizer is first
set up using the totalizer function in Math Level 2. The time
duration of the totalization is set using Coefficient A. If
Coefficient A is set to 0, then the totalizer will run indefinitely.
Otherwise, it will totalize over the specific time interval
programmed using Coefficient A, print the totalization result on
the chart at the end of the time period, reset the totalizer to
zero and start over again. Coefficient B is used as a scaling or
multiplier in the totalization equation. Coefficient C is used to
set the time units of the flow measurement. An example of how
to set up a totalization using the Math is shown below:
MA1 = Totalization (Math 2)
MA 1 Reset = No
This example will totalize Analog Input 1 for 1 Hour, 15 minutes
as Eng. Units per minute, (such as gal/min), print the result and
start over. The Backup feature is used to determine if the Math
Result is to be stored in the event of a power loss. This is
either Enabled or Disabled depending on the customer need.
Start and Reset can be programmed to have the Digital Inputs
control the math computation. In this case, they are not used
and the Totalization runs based on the programmed time
To print the results on a periodic basis without resetting the
totalizer requires the use of the Periodic Timer function in
Math Level 3. To accomplish this, the timer function is set up
to generate an output of 1 or 0 which is then tied to a soft
alarm which has been programmed to Print on Alarm the Math
Results. An example of this is as follows:
MA2 = Periodic Pulse (Math 3)
MA 2 Coef A = 0 Seconds
MA 2 Coef B = 2.00
MA 2 Coef C = 600.00
MA 2 Reset = NO RESET
This will create a 2 second pulse every 10 minutes which is
then used to trigger the Print Math on Alarm. The Alarm
Function is set up as follows:
Recorders – Totalization
AL1SP VALUE=1 (timer output)
The DPR100 can calculate a Grand Total by using the Addition
Math function and adding the desired Totalization Math
Results. The DPR100 is limited to six math results and the
addition can only add 2 results at a time, therefore the
maximum number of totalizers that can be added together is 3.
An example of how this could be done is shown in Fig 4.

Fig. 5.
Math Results can be assigned to a Chart Trace if they need to
be recorded on a continuous basis. This would be set up under
the CHART configuration item of the recorder and requires the
use of one of the Chart Channels (DPR180 has 24 Traces
max. / DPR250 has 32 Traces max.) The channel would be
configured to record MATH instead of Analog Inputs or
Communications Values.
Displaying the Math Results would be done using the
DISPLAY key on the front of the recorder. The values
displayed would follow the same format used for the printing of
math results. The limits of the Math are -9999999 to 99999999
when using the decimal format and -1e38 to 1e37 for the
exponential format.
Starting, Stopping and Reset of the Math Results can be
controlled using the Digital Inputs or Alarms of the recorder or
they can be set to run Continuously. These are programmed
when the Math is initially set up. The DPR180/250 currently
does not contain a Sync On Time Math function like the
DPR100 so the Digital Inputs have to be used if it is necessary
to sync the results to a real time clock.
The DPR180/250 can calculate a Grand Total by using the
Addition Math function and adding the desired Totalization
Math Results together. Since the Addition function can add up
to 3 Variables together at once, it provides more capability than
the DPR100. A similar method as shown for the DRP100
would be used to calculate this Grand Total. (Fig 4)
The totalizer does have a low cutoff that can be programmed
that prevents the integration if the input signal if it goes below
this value. The totalizer can be reset using a discrete input, an
internal status, the keypad or the keypad reset can be locked
out. The totalizer time base can be set for Seconds, Minutes,
Hours or Days. Fig. 6 shows how the totalizer display looks on
the VRX100 Video Recorder.
Totalizer Data Storage is set up the same way any of the other
data storage parameters are set up. The data can be stored in
a trend file or unit data file and with each record the data is
time stamped. Fig. 7 shows the SCF Software Configuration
screen which is used to configure the totalizer function on the
recorder when SCF is used.
Totalizer Upgrades
All of the recorder products that support the Totalizer function
can be upgraded in the field to add the totalizer option if it was
not originally ordered with the recorder.

In most cases, this requires either replacing the product prom
or adding the math function to the recorder. The following are
