Easy Totalizer Configurator

e.g. Source channel is recording in gallons per hour
e.g If want the totalizer output to be in gallons x 1,000, select units x 1,000. With this selection a real total of 1,800,000 would read as 1800. NOTE: The totalizers output is directly related to the source channel's unit of measure, i.e., if your source channel is measuring in Millions of Gallons per Day (MGD), the output of the totalizer will already be in millions. A selection of units x 10 would give an output in gallons x 10,000,000.
Calculate

Use the following numbers to configure your totalizer.

Totalizers made easy

(or what is a Totalizer Factor anyway?)

All Chessell Recorder totalizers act in the same way. The value of the input channel or DV is divided by the factor each secondand the result is stored. Whole numbers are sent to the totalizer value as they are accumulated. The basic factor is the number of seconds in the measured unit-of measure, i.e.

  • FEET PER SECOND (FPS) = 1.0 sec
  • GALLONS PER MINUTE (GPM) = 60 sec
  • STANDARD CUBIC FEET PER HOUR (SCFH) = 3,600 sec
  • MILLIONS OF GALLONS PER DAY (MGD) = 86,400 sec

EXAMPLE: A flow of 100 GPM would have a factor of 60 (seconds). Each second at a constant 100 GPM, 100/60 would be stored. At the end of 60 seconds, the value would be 100/60 X 60 or 100 GAL.

The main difference between the different model recorders is how this factor is formatted. In the 340 and 392 recorders, it is in the following format (scientific notation):

  • FACTOR = MANTISSA x 10 EXPONENT

While 4xxx recorders use simple multiplication:

  • FACTOR = PERIOD SCALAR x UNIT SCALAR

The factor in a 5000 series recorder is entered solely as the period scalar.In either case, any scaling should be done by adjusting the unit scalar. The period scalar should be left as shown below.
