Environment:

• Sewer manholes / inspection wells
• Urban drainage pipelines
• Flood-prone low-lying areas
• Stormwater networks and pump stations

Medium:

• Rainwater, sewage, mixed wastewater
• High turbidity, debris, and sediment environments

Conditions:

• Fully submerged, humid, and corrosive underground environments
• No stable power supply in many locations
• Remote distributed monitoring points

Micro-Power Radar Water Level Sensor

• Non-contact measurement inside manholes
• Immune to mud, debris, foam, and condensation
• Works reliably in fully humid underground environments
• High stability during heavy rainfall events

Power Supply System

• Large-capacity lithium battery
• Optional solar-powered configuration
• Designed for long-term unattended operation

Low-Power 4G Communication Module

• Real-time data transmission to cloud platform
• Supports distributed city-wide monitoring networks
• Stable signal in underground environments

Urban Water Management Platform

• Centralized dashboard for all monitoring points
• Real-time water level visualization
• Automated threshold alarm system

Radar sensors installed inside:

• sewer manholes
• drainage inspection wells
• flood-prone pipeline junctions

Installation method:

• Top-down mounting inside manhole shaft
• Non-contact measurement toward water surface
• Fully sealed waterproof design

Data terminal:

• Installed in outdoor control cabinet or remote station

Why Radar Works in Manhole Environments

Compared with ultrasonic or contact sensors:

• No clogging from sewage or debris
• No performance loss in high humidity
• No contact with corrosive wastewater
• Stable in fully enclosed underground conditions

Ideal for long-term unattended urban infrastructure monitoring
