A process control unit (PCU) controls the blending unit which is designed from fairly standard and readily available over-the-counter supplies. Operating ranges for the Blending Units are pre-programmed into the ladder logic system of the PCU from each product stream and can be remotely monitored. Simple and scalable design allows for inexpensive and convenient outsourcing to select qualified fabricators around the world who meet APT's strict criteria.
