Reducing pressure in water distribution systems is a proven technique for reducing leakage and the frequency of bursts. Conventionally, pressure reduction is achieved by a Pressure Reducing Valve (PRV), which delivers a fixed outlet pressure to the network.

The Modulo is an 'hydraulic-less' electronic controller that compensates for headloss downstream of the PRV and reduces night-time pressure. Solenoid valves and filters used in conventional pressure controllers affect system reliability. Modulo does not use solenoid valves or filters. It offers significantly higher reliability and can be used in situations where other systems may fail. Modulo requires only two connections to the PRV and is easily set up using the "Modulo Wizard" software on an hand-held PDA.
