Reading Flow Meters With Revenue-Grade Accuracy Through Your SCADA, Telemetry, Or Building Automation System

  1. 1. Jim Mimlitz SCADAmetrics Reading Flow Meters With Revenue-Grade Accuracy Through Your SCADA, Telemetry, Or Building Automation System © 1995-2013 COPYRIGHT SCADAMETRICS ALL RIGHTS RESERVED.
  2. 2. © 1995-2013 COPYRIGHT SCADAMETRICS ALL RIGHTS RESERVED. Flow Meter Reading Technology Background… Flow Meter Industry Serves 2 Traditional Applications RESIDENTIAL METERS PURPOSE: Billing MONITORING: Monthly Reads (AMR) COMMERCIAL/INDUSTRIAL METERS: PURPOSE: Process Monitoring, Control, Alarming MONITORING: Continuous Reads (SCADA, Telemetry, Building Automation) SCADAmetrics
  3. 3. Residential 1980‟s – Digital Encoders Touchread 1990‟s, 2000‟s – Improved Reliability Digital Encoders Radio Read Phone Read Revenue-Grade Accuracy SCADA/Telemetry, Bldg Automation © 1995-2013 COPYRIGHT SCADAMETRICS ALL RIGHTS RESERVED. Electronic Meter Reading Technology Timeline… Low Volume Automation Meter Reading Stalled In 1970’s-Era Technology High Volume Residential Meter Reading Technology Advancing Rapidly SCADAmetrics 1970‟s – Pulse Generator 1st Generation Remote Reading 4-20mA Signaling
  4. 4. Good Flow Rate Info Moderate/Severe Totalization Errors High-Speed Pulse (eg 1 Pulse Per Gallon) Flow Rate Info Takes Long To Develop (eg. 10+ minutes) Better Totalization Low-Speed Pulse (eg 1 Pulse Per 1000 Gallons) Excellent Flow Rate Info Poor Totalization 4-20mA Signal (eg 4mA=0 gpm, 20mA=800 gpm) © 1995-2013 COPYRIGHT SCADAMETRICS ALL RIGHTS RESERVED. Pulse & 4-20mA Signal Limitations… SCADAmetrics
  5. 5. • Unable To Distinguish Between Forward And Reverse Flows Generally Same Pulse or 4-20mA Signal Regardless Of Flow Direction • Requires Continuous Power Generally Not Compatible With Small Solar Panels • Requires Manual Synchronization Must Regularly Re-Adjust Start Count Within Host Telemetry/SCADA System • Pulse Methods Provide No Meter Fault Information Example: Cannot distinguish between „no flow‟ and a cut signal cable. High-Speed Pulse, Low-Speed Pulse, 4-20mA Signaling © 1995-2013 COPYRIGHT SCADAMETRICS ALL RIGHTS RESERVED. More Pulse & 4-20mA Signal Limitations… SCADAmetrics
