TOTALIZER TIME BASE

This is the time base used in Totalizer accumulations. If the Totalizer is being

accumulated through a user input programmed for Batch, then this parameter

does not apply.

The totalizer accumulates (integrates) the relative Input value using one of

two modes. The first is using a time base. This can be used to provide an

indication of total flow, usage or consumption over time. The second is through

a user input or function key programmed for Batch (one time add on demand).

This can be used for weighing applications where accumulation is based on a

completed event. If the Totalizer is not needed, its display can be locked-out and

this module can be skipped during programming.

TOTALIZER SCALE FACTOR*

For most applications, the Totalizer reflects the same decimal point location

and engineering units as the assigned Input Display. In these cases, the Totalizer

Scale Factor is 1.000. The Totalizer Scale Factor can be used to scale the

Totalizer to a different value than the Input Display. Common possibilities are:

1. Changing decimal point location (example tenths to whole)

2. Average over a controlled time frame.

Details on calculating the scale factor are shown later.

If the Totalizer is being accumulated through a user input programmed for

Batch, then this parameter does not apply.

The Totalizer can be reset to zero on each meter power-up by setting this

parameter to reset.

* The decimal point position is dependent on the selection made in the

“Totalizer Decimal Point” parameter.

TOTALIZER HIGH ORDER DISPLAY

When the total exceeds 5 digits, the front panel annunciator flashes (if

assigned to A, B, or C display). In this case, the meter continues to totalize up

to a 9 digit value. The high order 4 digits and the low order 5 digits of the total

are displayed alternately. The letter “” denotes the high order display.

TOTALIZER BATCHING

The Totalizer Time Base and scale factor are overridden when a user input or

function key is programmed for store batch (). In this mode, when the user

input or function key is activated, the Input Display reading is one time added

to the Totalizer (batch). The Totalizer retains a running sum of each batch

operation until the Totalizer is reset. This is useful in weighing operations, when

the value to be added is not based on time but after a filling event.

TOTALIZER USING TIME BASE

Totalizer accumulates as defined by:

Input Display x Totalizer Scale Factor

Totalizer Time Base

Where:

Input Display - the present input reading

Totalizer Scale Factor - 0.001 to 65.000

Totalizer Time Base - (the division factor of )

Example: The input reading is at a constant rate of 10.0 gallons per minute. The

Totalizer is used to determine how many gallons in tenths has flowed.

Because the Input Display and Totalizer are both in tenths of gallons, the

Totalizer Scale Factor is 1. With gallons per minute, the Totalizer Time Base

is minutes (60). By placing these values in the equation, the Totalizer will

accumulate every second as follows:

10.0 x 1.000 = 0.1667 gallons accumulate each second

This results in:

10.0 gallons accumulate each minute

600.0 gallons accumulate each hour

TOTALIZER SCALE FACTOR CALCULATION EXAMPLES

1. When changing the Totalizer Decimal Point () location from the

Input Display Decimal Point (), the required Totalizer Scale Factor is

multiplied by a power of ten.

Example: Input () = 0.0

Input () = 0.00

(x = Totalizer display is round by tens or hundreds)

2. To obtain an average reading within a controlled time frame, the selected

Totalizer Time Base is divided by the given time period expressed in the same

timing units.

Example: Average flow rate per hour in a 4 hour period, the scale factor

would be 0.250. To achieve a controlled time frame, connect an external timer

to a user input programmed for . The timer will control the start (reset)

and the stopping (hold) of the totalizer.
