Water Service and Meter Reading

Encoder Receiver Transmitter (ERT)

Leak Mode & Leak/Flow Indicator

Leak/Flow Indicator 1 cubic-ft = 7.48 gal | 1 ccf = 748 gallons | 1 ccf = 100 cubic-ft Leak Mode Leak Mode. Continuous consumption over the last 24-hours) 1st Screen: meter read 2nd Screen: billing read and flow indicator 4th Screen: Flow rate in gallons per minute

• Step 1 – Prior to a bill being sent, the billing system performs a high low quality control check

(compares the previous readings to the current readings)

• Step 2 – If high low, the a field activity is created to verify the high low
• Water meter, register, and ERT combination (no equipment mismatches)
• Register and ERT readings are correct (same reading)
• No City or Customer leaks
• Step 3 – If any of the above, an adjustment is made and a corrected bill is sent to the customer

Billing and Meter Accuracy

Meter Chamber Meter Register ERT

Increased meter read accuracy of AMR vs. manual reads

• Pre-AMR (manual meter reading) resulted in a 97% average

read accuracy.

• On average 3% of the monthly meter readings resulted in

either a high or low meter reading, which would have resulted in a high or low monthly bill.

• Today (Post-AMR), we have a 99.9% meter read accuracy.

Field Check

• Check Equipment Installation (mismatches). Water meter, register, and ERT combination
• Verify Read. Register and ERT readings are correct
• Check for Water Meter Leaks. City side
• Field Consumption Test. Volunteer basis

Equipment Check

Confidence Level: 95% Confidence Interval: 5% 25,870 Meters Random Sample: n = 400 Meters

Equip ipment Check Results

• All 400 Meters
• Equipment Installation:

1 of 400 incorrect

• Verify Read: 100% correct
• City Leaks: 0 leaks
• Field Consumption Tests (about half)
• High: 0 (no over charges)
• Low: 1 (under charged)
• Dead: 2 (under charged)
