Sensor monitoring
Remote drain, sewer and water level monitoring
Rugged IoT data loggers that send level, flow and rainfall readings to the cloud, so you can act before a drain overflows.
How remote level monitoring works
Sensors are placed at key points in a drain, sewer or tank. They measure the water level, and can also measure flow rate, rainfall or water quality.
A battery-powered data logger reads the sensors on a schedule and sends the data over the mobile network to a cloud dashboard. You see the levels in near real time and get an alert when a threshold is crossed.
Sensor measures
Water level, flow, rainfall or temperature.
Logger records and sends
Stores the readings and uploads them over 4G.
You get alerted
Dashboards and alarms when levels rise.
Who uses it
Councils
Prevent overflows and manage stormwater and wastewater.
Water utilities
Plan maintenance with accurate level data.
Construction
Monitor drains near works to avoid disruption.
Environmental agencies
Protect water quality and catch pollution early.
The logger
Digital Matter Hawk data logger
The Hawk is a rugged IoT data logger built for wet, corrosive and dirty places like sewers. Its configurable inputs connect to a wide range of industrial sensors.
