Every reading from your water meter is automatically assessed for quality. Here’s what the quality codes mean and how we keep your data accurate.
Your meter data is graded using the national NEMS quality coding standard. These three codes apply to measured data and reflect its quality:
Your meter is verified, data is complete, and readings meet all quality requirements. This is the highest quality rating.
Data is measured and reasonable but doesn’t quite meet all top-tier requirements — perhaps a minor gap or verification coming due soon.
Data has been measured but has a known issue — such as an overdue meter verification, significant gaps, or a manual reading.
Other categories — these classify data rather than rating its quality:
Estimated or gap-filled data
Quality not yet assessed
No reading recorded
Awaiting quality check
For consent compliance, we calculate totals directly from the raw pulse counter on your meter — the most accurate method possible, with zero rounding errors.
Your meter reports a reading every 15 minutes, giving a detailed picture of water use throughout the day. That’s 96 readings per day.
Every reading is automatically assessed against national standards. Quality codes are assigned without manual intervention — consistently and transparently.
All daily totals use New Zealand local time (Pacific/Auckland), so your daily and seasonal summaries match real-world days — including daylight saving transitions.
Your water meter is verified every 5 years by an accredited Blue Tick installer (IrrigationNZ). This test confirms the meter reads within ±5% of actual flow.
Data quality ranges from Missing (QC 100) to Good (QC 600). Most telemetry data from verified meters with good connectivity achieves QC 600.
