Quantum 3

Superior Pumping Station Controller

Quantum 3

Quantum 3 is a fully-featured pump controller, using Pulsar's unique non-contacting ultrasonic technology including DATEM digital echo discrimination to provide sophisticated level management. Quantum 3 can be programmed to provide an alarm based on the time remaining before the station or well spills over. Vital for utilities who face the risk of prosecution if a station pollutes the local environment. Quantum 3 adds the ability to interface with up to four Flow Pulse non-invasive flow monitors, so all flow-rate based alarms and control is based on measured rather than calculated flow.

Quantum 3 Features:

  • Can assign a Flow Pulse to either a pump, a main outlet or stand-alone measurement
  • 24VDC output supply capable of supplying 4 Flow Pulse units
  • 'Burst and Block' now based on real flow
  • Auxiliary display can now cycle through each Flow Pulse and display real flow
  • Totaliser sums real throughput rather than deriving from level measurement
  • Has universal power supply input of 22-28 VDC and 85-264 Vac
  • Storm detection alarm
  • NRV leakage alarm
  • Time to spill calculation
  • Automatically resets tripped pumps
  • Easy prompt led set up
  • RS485 Modbus and Profibus DP V0 and V1 options
  • Pump efficiency alarm function
  • Peak power tariff avoidance
  • This unit can also be configured using Pulsar's PC Suite software
