Gauge and well telemetry
Level, flow and groundwater sensors report at fixed intervals over cellular or satellite links; gaps and drift are flagged automatically.
The Global Centre for Risk and Innovation (GCRI)
Sensing and telemetry bring the gauge, the well and the pipe network online: continuous levels, flows, pressures and quality readings that forecasting and operations depend on.

Sensors, IoT and observation networks collect continuous measurements of physical, environmental and operational conditions. They provide the real-time inputs that early warning and asset monitoring depend upon. In water, climate and hazards and critical infrastructure, observation networks enable early warning and condition-based maintenance. They reveal how stresses in one system appear in connected systems in near real time. The canonical description is on the STEM Commons.
Level, flow and groundwater sensors report at fixed intervals over cellular or satellite links; gaps and drift are flagged automatically.
Pressure, flow and quality sensors across a distribution network locate bursts, contamination and intrusion events.
Community and low-cost sensors extend coverage where networks are thin, with calibration against reference instruments and their uncertainty carried into every use.

Data from the source register feeds the methods; calibration and an independent test gate the estimate and its limits; the decision stays with the competent authority.
Fig. 01Nodes carry their type, metrics and state; connectors show what feeds what; the gates are the validation steps; the timeline is one application. Design of the method’s use, not a record of a run.
Datasets and records used by sensors, IoT and observation networks on this platform, with the role each plays and the label its values carry. Sources are listed in the source register.
| Data | Role | Label |
|---|---|---|
| Telemetered gauge networks | Real-time flows and levels | OBSERVED |
| Utility SCADA | Pressure, flow and quality | OBSERVED |
| Low-cost sensor networks | Coverage extension | ESTIMATED |
Sensors are calibrated against reference instruments and checked through co-location and redundancy. Data quality flags and automated range checks catch faults.
| Check | How it is done |
|---|---|
| Calibration schedule | Every sensor has a calibration record; readings outside the calibrated range are labelled |
| Quality flags | Drift, spikes and gaps are flagged in the data stream, never silently filled |
| Security review | Telemetry and control networks are assessed for unauthorised access |
Sensor drift, power loss and connectivity gaps degrade data during the events of most interest. Dense networks raise security and privacy concerns.
Critical Infrastructure stewards sensors, IoT and observation networks for the Consortium and reviews how it is applied across platforms.

The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
