Smart Water Meters Mechanical Meters Volumetric Moving part Woltmann Commercial & Industrial Bulk water Static Meters Electromagnetic Ultrasonic No Moving part No pressure drop Intelligent outputs Smart water meter definition: Solid State Technology Long term high accuracy Large flow turndown Low cost of ownership AMI ready Integrated communication Residential Application intelligence Consumption profile Data logging Leakage alert Billing information

Smart Water Meters Siemens Answers Sitrans FM Mag 8000 Designed for the water industry applications: Network Managenet Leakage monitoring Billing Irrigation in the near future 70% of all used water is used for agricultor

Leakage Monitoring Meter Requirements Battery Operated 6-10 year Burry able & IP 68 submersible Bidirectional measurement: Forward, Reverse, Net Widest dynamic range Accuracy at low flow - nightflow detection Datatransfer : puls; Modbus or GPRS Siemens Mag 8000 answers all requirements, and more

Smart Billing with Smart Meter How to start? Start with the large users Commersial & Bulk usage Industries Irrigation 50% of the water uses can be measured with very few water meters (typical 3%) Business (real) case Woltman meter DN 50-80 25-50.000 m3/year 5-10 years old efficiency loss=3-8% 1,50 / m3 (Large users higher) Utility Loss, year 5: 10-30.000 Siemens answers Mag 8000 CT Design & certified for billing MID 001 approved High accuracy even at very low flow: Tourist sesion Irrigation sesions Day & Night flow Siemens answers Manufacturing & Calibration Accredited to ISO 17025

Irrigation Application Re-charge of the irrigation system Fertilization Flow Monitoring & Billing Magnetic Very Accurate Obstruction Free No Moving Parts Virtually No Maintenance Lowest Installed Cost Sitrans FM 8000 Battery Powered Data logger Modbus communication GPRS Data transfer
