Pressure control can be the simplest and most immediate method of reducing leakage, and has been proven to reduce burst frequency. Active pressure management using electronic pressure controllers enables pressure to be optimised with changing demand. ControlMate FM intelligently controls PRV output pressure against the zone's actual demand (flow modulation) or can respond to a pre-programmed time of day.
The system supports closed loop "learning" and override from the critical point. Si-Clops 2 uses ControlMate FM with a critical point logger and intelligent ControllerCom communications module to provide self-learning flow modulated control. The control parameters are automatically optimised against logged data fed from the CP logger to optimise pressure at the critical point, thereby maximising water savings.
ControlMate FM has recently been redesigned by HWM to incorporate a range of new features including recessed buttons, clearer labelling and the option of being powered by external battery packs to extend operational life.
