- Model Quantum 2+ - Intelligent Pumping Station Controller



The Quantum 2+ controller includes all the features within Quantum 2 with the exception of the second mA output for pumped flow rate. The Quantum 2+ controller instead features 1x mA output and the addition of 1x mA input.

Quantum 2+ is a fully-featured pump controller, using Pulsar's non-contacting ultrasonic technology including DATEM digital echo discrimination to provide solid performance and sophisticated level management. Quantum 2+ includes 10 relays (digital outputs) and 7 digital inputs, and have optional RS485 digital communications (Modbus and optional Profibus DP V0 and V1) allowing the status to be monitored and the unit to be programmed remotely. Additionally Quantum 2+ has the option of a large on-board data-logging facility (256kb).
