ST Engineering Telematics Wireless
Cellular AMI & Smart Water Solutions
Connect compatible water meters and field sensors to a unified management platform. US Meter Supply helps utilities automate meter reading, monitor system conditions, and turn field data into actionable information.
Automated Meter Reading
Reduce manual collection with cellular meter reporting.
Water Loss Insights
Identify unusual consumption and potential customer-side leaks.
Pressure & Level Monitoring
Monitor critical locations and receive configured threshold alerts.
Centralized Management
Bring meter data, assets, maps, and reporting into one platform.
System Overview
How It Works
Three steps from field device to actionable data.
Connect
A compatible meter or sensor connects to the appropriate SIENNA interface unit.
Transmit
Supported endpoints send readings through NB-IoT/LTE-M cellular connectivity. Supported configurations also provide walk-by or drive-by collection using a mobile data collector. Note: meter reading intervals and data transmission intervals are configured independently.
Manage
BrightCity organizes readings, alerts, asset information, and reports for utility staff.
