Compare total cost over a common ownership period:
Meter + accessories + installation + commissioning + communications infrastructure + recurring service + maintenance/replacement + operational disruption.
Ask quotations to separate the sensor/body, display, transmitter, pulse pickup, power supply, gateway, antenna, SIM, cloud platform, software integration and commissioning. Include strainers, reducers, flanges, cabinets and civil work when required.
An inexpensive meter may still be a good choice if manual reading meets the need. A more expensive connected meter can be worthwhile where it reduces reading labour or provides useful, actionable data. Neither conclusion follows from technology alone.
Illustrative subscription calculation: at a hypothetical ₹200 per device per month, 100 devices cost ₹20,000 per month, ₹240,000 per year or ₹1.2 million over five years, before taxes or changes in tariff. This is arithmetic for budgeting, not a supplier quotation.
Price battery or whole-meter replacement, service visits, calibration/testing and data export. Agree on what happens if the software subscription ends or the supplier discontinues the communications platform.
Questions for a connected-meter supplier
- Who owns the meter readings, encryption keys and device configuration?
- Can data be exported through a documented API or standard file format?
- What fields, units, timestamps, quality flags and history are available?
- Can the hardware work with another compatible gateway or platform?
- Are SIM, connectivity, hosting, updates and support included, and for how long?
- What is the battery replacement procedure and its effect on sealing/warranty?
- What remains usable during an outage or after subscription expiry?
- Who is responsible for correcting missing data, clock errors and failed devices?
