Metering
All field activities associated with revenue collection is grouped under Metering. Expenditures include labor and vehicles for meter reading, connects, disconnects and all activities associated with Measurement Canada certification of new meters and re-certification of meters in service.
Meter Types
For Residential electricity metering in the Nelson Hydro service area there are currently two main types of meters used;
- C1SR: These meters are used mainly on single family residential applications,
- CN1SR: These meters are used mainly in apartment and strata developments
RF Transmitter Types
The meters use an R300 personality module to communicate with the meter reading device. The R300 modules used at Nelson Hydro come in two variants as specified by -2 or -3. We have requested further information from the manufacturer on the characteristics of these modules and can summarize the data we currently have as follows.

Identifying Meter Nameplate Data
A typical meter faceplate from Nelson Hydro is shown in the Memorandum (PDF). CN1SR meters are similar.
