River Level Monitoring

Stop work early before flooding, no manual watch needed

Water-level sensors installed in rivers or open channels measure 24/7, with graded alerts sent instantly to site representatives and safety officers. Trends can return to customer systems via API.

What is SenseOS river level monitoring?

SenseOS river level monitoring installs water-level sensors in rivers or open channels to measure water levels 24/7. When levels reach a graded alert threshold, the platform instantly notifies site representatives and safety officers, so work can stop before flooding without anyone watching the water manually. Units run on solar or battery power, need no mains supply or foundation, and are usually installed within half a day.

Key facts

Measurement
Continuous 24/7, no manual patrols
Alert levels
Low to critical, with recipients set per level
Power
Solar or battery, about 2 years in normal use
Installation
Within half a day on existing structures or a simple bracket
Data
Stored in the cloud, Excel/PDF export and API integration

Who it is for

  • Construction works beside or across rivers
  • Works near open channels and major drainage channels
  • Sites that need water-level-based stop-work criteria
  • Projects that report data regularly to clients or government

How it works

  1. 1Install a water-level sensor in the river or channel
  2. 2The sensor measures and uploads levels around the clock
  3. 3The platform compares levels and trends against each threshold
  4. 4Site representatives and safety officers are alerted; data can return via API

How it works

1 to 4 water-level sensors, triggered by level

When water reaches each sensor, the matching alert level is triggered.
