The pump is now calibrated. As the pump runs, you will see that the total will
increase by this calibration standard.
#
NOTE:
Each pump and each tubing size will need its own calibration.
13.4 Pump Period
At the bottom of each pump gauge is the Period(sec) pane (
see Figure 45
):
Figure 45: Pump Period(sec)
Use this edit box, and its associated touchpad, to enter a pump cycle time in seconds.
For example, if the pump setpoint is 30%, setting a period of 5 seconds (as illustrated)
will cause the pump to run 1.5 seconds, stop for 3.5 seconds, then cycle back on again.
#
NOTE:
Running at a very low percentage renders the totalizer’s results
inaccurate. We recommend the use of smaller tubing to avoid choosing a
very low percentage for the pump setpoint.
13.5 Installing an External Variable Speed Pump
CAUTION!
When selecting an external pump to operate with your system, please
consult with your local sales representative to be sure the model you
choose is compatible with your BioFlo 415.

Interface
