Multi-function metering controller
07 June 2016
The new "Control Freak" electronic controller from Wanner International provides motor speed control for Hydra-Cell Metering Solutions pumps (or Hydra-Cell bare shaft pumps in metering applications) and is able to control multiple pumps with Variable Frequency Drives (VFDs) from a single point.
Because motor speed is directly proportionate to flow rate in a Hydra-Cell pump, high accuracy can be achieved through the use of VFDs. With an easy to use, 7" colour graphic touch-screen user interface, the state-of-the-art technology provides optimum speed control based on desired flow and pressure ratings.
Users can enter the desired flow rate or volume along with system pressure and the controller automatically runs the pump at desired flow rate or volume total/time, or in pre-set batches. With four configurable on-off relays, ten separate batch set-up screens and two user-configurable analogue input displays, the versatile controller enables programming for flow rate or totalisation.
