Calculate the smart meter inventory needed for a deployment, including installed units, replacement spares, and installation workload. Enter the number of service points, meters required at each point, spare allowance, crew productivity, and deployment window. The result rounds meter inventory and crews upward so the plan does not rely on partial hardware or fractional teams.
The total fleet is procurement inventory, while the crew estimate covers planned installations only. Spare units are not added to installation workload unless they are actually deployed.
Crew productivity should include travel, access failures, commissioning, and realistic working conditions.
For 25,000 service points at one meter each with a 3% spare allowance, total fleet size is 25,750 meters. At 30 installations per crew-day over 120 days, at least 7 crews are needed.
Meters are discrete units, so any fractional result requires one additional unit.
No. Crews are sized for base service-point installations; add planned spare deployments separately.
Yes. A weighted average can represent a mix of single-meter and multi-meter locations.
Base meters are divided by crew daily productivity and available workdays, then rounded up.
Only if the productivity input already reflects access failures, rework, and other field losses.
| Output | Rounding rule |
|---|---|
| Base meters | Ceiling of service points × meters per point |
| Spare meters | Total fleet minus base meters |
| Total fleet | Ceiling after spare allowance |
| Installation crews | Ceiling to a whole crew |
