The scale of infrastructure involved in delivering domestic and non-domestic water is huge. From ensuring there is enough water to meet demand, maintaining an extensive pipe network in hostile conditions and then treating and recirculating waste water. Measurement is vitally important across the spectrum of activities to ensuring efficient use of this valuable resource.
To manage leakage in a network water utilities have to measure volumes going into it via Distribution Input (DI) meters then at various points across the network; district meters, domestic meters and non-domestic meters. By comparing measurements at each point, leakage can be estimated and traced to allow fixes and leakage reduction. NEL can also help companies determine how accurate those readings are to allow increased measurement accuracy and commercial savings.
Using Data Reconciliation to Identify Measurement Issues Data reconciliation is a statistical technique that can be applied to networks to identify the presence and quantify the magnitude of significant fluid imbalances. Many companies perform simple mass balances based on flow measurements whereas data reconciliation takes this process a stage further by identifying which instruments are most likely to be responsible for any discrepancies.
Meter Technology Management With NEL’s laboratory facilities we can test metering systems in simulated real-life conditions – pressures, flow rates and temperatures – to ensure upon deployment readings accuracy is optimal.
Other areas we can help with are:
Meter system selection and design.
Ongoing meter calibrations.
Flow modelling using Computational Fluid Dynamics.
Uncertainty modelling to assess reporting accuracy.
