Example (See Graph):

A linear flow transducer with a DC output of 0 to 5 volts is calibrated for a maximum flow of 25 SLH. The transducer is connected to one channel of a POWERPOD-400which is CAL’d to read 25.000 at 5 volts input and has been programmed to display rate in SLH. The transducer is sending a constant 1.000- volt signal to the POWERPOD-400. What is the total flow after 40 minutes?

During one sampling interval, the TOTALIZER reads the one-volt signal and calculates the fraction of the possible full-scale value.

1 volt/5 volts or 0.20

The fractional signal value is multiplied times the CAL value 1/5 * 25 = 5

Then, because the channel’s programmed rate is in SLH (standard liters per hour), a factor of 1/3600 is applied to the result.

5 * 1/36000 = 1.389 x 10^-4 standard liters per sampling interval.

A constant signal received over a 40 minute time period would amount to 40 minutes * 60 seconds * 10 samples per second = 24000 samples. The TOTAL would be

2.400 E03 * 1.389 E-04 = 3 1/3 Std Liters.

If no rate is programmed on that channel, The TOTALIZER function is disabled for that channel and the display returns to its regular metering configuration.

To enable the TOTALIZER, press the MODE key. The MODE menu appears in the display. To select TOTAL, press 2, and then ENTER. The TOTALIZER menu allows the operator to select the desired channel. Press the number key that corresponds with the desired channel followed by ENTER. A TOTALIZER menu is presented that allows the operator to go directly to displaying whatever the Totalizer has currently stored as the total or to reset the counter. If DISPLAY is selected by pressing the number 1 key followed by ENTER, the display will return to normal with the most recently stored total being displayed on the appropriate line. If RESET is chosen by pressing the number 2 key followed by ENTER, the display returns with the total value reset according to the pre-selected counting mode presented in the table below with the Totalizer counting.
