Summary Purpose of Automated Meter Reading (AMR) system What does an AMR system entail? Summary Purpose of Automated Meter Reading (AMR) system What does an AMR system entail? University of Leicester's estate and It’s AMR system The use of AMR Maintenance of AMR Things to bear in mind when embarking on an AMR

The Purpose of AMR Eliminate manual meter read Better quality of data Help to The Purpose of AMR Eliminate manual meter read Better quality of data Help to understand energy and water usage profile Avoid energy and water wastage early Making it easier for legislative compliance Helps to justify energy efficiency and water savings projects Assists in bill validation and re-charges

Typical Meter Reading Installation Manual meter reading system Monthly or weekly meter reads using Typical Meter Reading Installation Manual meter reading system Monthly or weekly meter reads using clip board or handheld devices Manually enter the readings into the energy management software. Automated meter reading system Half-Hourly meter reads via a suitable method Meter reads transferred automatically into a database The energy management software uses this database for further analysis

What do you know about your meters? Gas - Do you know your MAM What do you know about your meters? Gas - Do you know your MAM (Meter Asset Manager)? National Grid / Energy Asset / Smart Metering System / Exoteric / Off Stream/ etc Electricity - Do you know your MOP (Meter Operator)? Siemens / EDF / EON / British Gas / etc Of course, you need to know your suppliers Meter location is important (plant room/boiler house/ pavement/ under kitchen sink/cleaner cupboard/etc)

Tips to Maintain AMR System Dedicated personnel resource depending on size of the system Tips to Maintain AMR System Dedicated personnel resource depending on size of the system Set alarms and monitor alarms on a daily basis It’s good practice to take 1 or 2 manual meter reads per year to reconcile the automated reads Site tree structure AMR providers to provide familiar reports

Finally …. Things to bear in mind Make sure you have valid business case Finally …. Things to bear in mind Make sure you have valid business case for the preferred AMR system Ensure you choose an appropriate data collecting system that works for your institution Speak to your utility suppliers, MOP and MAM Choose a user-friendly software Small contingency pot for unknown meters Ensure you have a maintenance contract for hardware and software, which suits your institution
