Remote control and automatic optimisation of your entire network
oNet enables remote control and automatic optimisation of pressure at PRVs and pumps across your entire network.
You can determine and set your own control philosophy for PRVs and pumps on the network. You can opt for a fixed outlet pressure knowing that it will be precisely controlled to that level with the minimum Factor of Safety, and confirm that that is what is being delivered. You can set up simple timed control. Or you can implement a control curve that you have manually calculated.
With automatic optimisation, oNet algorithms determine the optimal control philosophy for PRVs and pumps to achieve a targeted minimum control point pressure. The system automatically adjusts for flow-related headloss and delivers smooth and accurate control, including accommodating fire demand. The system learns and adapts to seasonal, cultural and growth related changes in demand over time.
You can set any combination of remote control or automatic optimisation of pressure well in advance using a simple calendar function. For example, if you have an area of the network serving a sporting or cultural event, you can schedule this requirement well in advance.
For PRV control, you can set constraints on how control is exercised in extreme circumstances to ensure that the network is protected. For pump control, this is incorporated into PLC programming.
oNet Benefits oNet delivers a wide range of major business benefits
By removing excess pressure, leakage levels fall by an average of 20%.
Less water being pumped at a lower average pressure leads to a significant reduction in energy consumption.
Burst Frequency Reduction
Through lowering maximum pressures and smoothly controlling pressure transitions, burst frequency is reduced.
Improved Customer Service
Target pressures can be delivered with a high degree of confidence; there are fewer network related complaints.
Asset Lifetime Extension
Owing to the reduction in burst frequency, the lifespan of infrastructure approaching replacement can be extended.
Operational Costs Savings
i2O customers save money from less ‘find and fix’ activity and fewer scheduled site visits.
