NOTE:
The following procedures refer only to the use of the BioFlo 4500
equipped with the ML-6100 controller .
The addition of nutrient via an assignable peristaltic pump can be controlled up to 100%, set
on a user-defined basis. The 0 to 100% setpoint adjustment will be directly proportional to
the duty pump cycle. This optional system can be set such that pump will stop when liquid
level reaches the level probe.
Typical settings for a nutrient control loop are as follows:
