+# Measurement Example Flows
+
+These flows are import-ready Node-RED examples for the `measurement` node.
+
+## Files
+- `basic.flow.json`
+Purpose: basic measurement injection and output inspection.
+
+- `integration.flow.json`
+Purpose: parent/child registration and periodic measurement updates.
+
+- `edge.flow.json`
+Purpose: invalid/edge payload driving for robustness checks.
+
+## Requirements
+- EVOLV `measurement` node available in Node-RED.
+
+## Import
+1. Open Node-RED import.
+2. Import one `*.flow.json` file.
+3. Deploy and inspect debug output.
