Planning this application?
Send the site count, signals, network, power and reporting target. We will return a hardware configuration for quotation.
Why it matters
Manual meter reading is slow, error-prone and expensive. Tenants, sub-meters and remote sites need accurate consumption data without sending someone to read a dial.
How it works
- 1Meters are read over RS485 / Modbus or pulse outputs by a data collector.
- 2A LoRa / NB-IoT / 4G gateway uploads readings on a schedule.
- 3Consumption, sub-metering and billing data are available remotely.
Is this the right page?
Use this page when electricity, water or utility meters must be read without manual rounds and the buyer can provide meter interfaces, pulse constants or register maps.
Facility metering context
Representative site context. Sensors, interfaces, enclosure, power and mounting are confirmed against the actual project before quotation.
What buyers usually need to monitor
Cumulative readings
Energy, volume or other totalized values used for operations, allocation or reporting.
Interval data
Demand, power, flow or rate data collected at an agreed polling and upload interval.
Meter health
Offline, communication timeout, power loss and last successful reading.
Data identity
Meter ID, site, channel, timestamp, units and scaling kept consistent across the fleet.
Where the hardware sits in the monitoring path
A planning view, not a fixed bundle. Signal type, protocol, power, network and the customer endpoint are confirmed before quotation.
Customer system
SCADA, BMS or customer-owned platform

Confirm before selection
- Confirm meter make, interface and protocol version.
- Provide register maps, data types, scale factors or pulse constants.
- Define polling and reporting intervals separately.
- Confirm whether the use is operational, allocation or regulated billing.
- Map site and meter identifiers to the customer system.

- RS485 topology and cable length
- Reading interval and retained fields
- Network and endpoint
- Country and number of sites
Scope boundaries
- Remote collection does not make a meter billing-approved; that depends on the exact meter and local rules.
- Register availability and read permissions must be confirmed from the selected meter documentation.

Buyer questions
Can one gateway read multiple meters?
Yes when addresses, baud rate, cable topology, polling load and gateway capacity are suitable.
Can pulse-output meters be included?
Yes when the pulse constant, electrical interface and counter behavior are documented.
How is missing data handled?
Buffering and retry depend on the selected gateway. State the outage duration and reporting gap the project must tolerate.
