2 Why Integrate Master Meter Data Into The SCADA System? Track Distribution System Flows In Realtime. Bulk Customer Billing & Automatic Reports. Detect and Zone Transmission Line Leaks. Increase Employee Safety. Improve Data Accuracy. Leverage Already-Existing SCADA System Infrastructure. The Bottom Line: Reduce Operational Costs

3 Track Distribution System Flows In Realtime GPM GAL GALLONS GPM SCADA Systems Excel At: Collecting Large Amounts of Sensor Data Within Short Time Intervals Graphical Presentation of Data Alarming Unusual Conditions (Audible Alerts, Text Messages, etc.) Graphical Presentation of Historical Trending Charts

4 Bulk Customer Billing & Automatic Reports Connect SCADA Database to: Billing Software System Excel Spreadsheets

5 Detect and Zone Transmission Line Leaks Pump Station #1 Flow RE Water (Bulk Customer) System Flow Standpipe Storage Flow = Approximate Residential And Business Usage Water Company SCADA Server Standpipe Storage Bulk Water Customer (RE Water Corporation) Pump Station #2 Overnight Usage Trends Provide A Useful Measure Of Potential Water Leaks Flow (gpm) Purchase Point From Supplier (City of Albion, IL) Residential And Business Customers Pump Station #1

6 Increase Employee Safety Meter Vaults Safety Hazard. OSHA Confined Space Compliance.

7 Improve Data Accuracy 4 Below-Grade Master Meters Eyeball-Read By Human Meter Reader. (Errors) 4 Master Meters Machine-Read By SCADA System. (Error-Free) SCADA/Meter Instrumentation Saved The Utility $14K On This Month s Bill.

8 Leverage Already-Existing SCADA Infrastructure Computer Hardware Computer Software Communication Infrastructure (Radio, Fiber-Optic, Etc.) Remote Sites (eg Water Towers, Pumping Stations)

9 How To Integrate Master Meters Into A SCADA System? Case Study I Licensed FM Radio Telemetry Case Study II Cellular Ethernet Telemetry Case Study III Extraterrestrial Satellite Radio Telemetry

10 Case Study I Licensed FM Radio Telemetry Project Goals: Collect Data From 34 Master Meters (Various Brands) Using SCADA System. 4 Readings Per Day. Revenue-Grade Accuracy Of Meter Readings. Accelerated Leak Detection. Minimize Recurring Costs: Low Energy Footprint (Solar Solution) Eliminate Manual Read Payroll Reduce Fuel and Vehicle Wear/Tear Reduce Data Entry and Reporting Time Increase Employee Safety miles 3 Year Investment Payback. ABS Water Cooperative (Clayton, IL)

11 34 Master Meters Sensus Badger Several Meter Brands Mixed Throughout System Customer Desired To Utilize Existing Meters

12 Revenue-Grade Accuracy Utilize Absolute Encoder Technology No Pulse Signaling (Pulse-Counting Errors) No 4-20mA Signaling (Integration Errors) Required Register Retrofits: Sensus ICE Registers Badger ADE Registers Badger ADE Register Sensus ICE Register

13 Minimize Recurring Costs Solar-Power Eliminated Need For Electric Utility Service: No Up-Front Utility Hookup Charges No Monthly (Minimum) Usage Charges

14 Telemetry Hardware Diagram Lexan Window Visual Read Backup Solar Panel (50W) and Battery Charge Controller EM-100 EtherMeter SCADA/Meter Gateway DL-3400 FM Telemetry Radio Fusing 12V Battery Radio Communications Using RS-232 and Modbus/RTU Industrial Protocol Water Towers Were Natural Repeaters For Meters In Low-Lying Areas.

15 Reduced Data Entry and Reporting Time Software Library Created That Linked the SCADA Database To Excel Spreadsheets. Automatic and Fast Report Generation. Data Analytics Quantifies Usage Anomalies/Leaks. Data Transcription Errors Eliminated.

16 Case Study II Cellular-Ethernet Telemetry Utility: Missouri American Water Company (Saint Louis, MO) Project Goals: Collect Meter Data From 20 Custody Transfer Meters (Various Brands) Using Cellular Ethernet Technology and the Existing SCADA System. Main Purpose = Billing. Revenue-Grade Accuracy Required. Readings Every 15 Minutes. Minimize Recurring Costs: Low Energy Footprint (Use Solar Wherever Power Not Available) Eliminate Ineffective Legacy System and Associated Monthly Contract Interface With Bulk Customer Telemetry Equipment.

17 Cellular Ethernet System IMPROVED MASTER METERING SYSTEM Local Cellular Tower Infrastructure Private Cellular Network Master Meters Retrofitted with Encoder-Type Registers Water Company HQ Industrial Ethernet Protocols Cellular Carrier Private Cellular Network For SCADA Security. Data Communications Using KepServerEx. Nice Extra: Modbus/UDP Industrial Protocol (not Modbus/TCP). UDP Protocol Achieved Order-of-Magnitude Decrease In Billable Cellular Kilobytes.
