HWM is pleased to announce the launch of SpillSens, our new low-cost multi-alarm digital float sensor.

SpillSens is an easy to install, low maintenance float sensor that acts as an early warning system for blockages and sewer overflows.

ATEX-approved and built to withstand harsh sewer environments, SpillSens uses digital positioning technology to monitor rising levels in the waste water network.

SpillSens hangs in the sewer chamber, constantly monitoring the tilt angle of the sensor.  When sewer levels rise past a pre-determined level, the contents of the sewer disturbs the sensor, causing it to float and the tilt angle to increase.

Each SpillSens sensor is connected to a data logger.  When the tilt level reaches a specified angle the logger uses cellular telemetry to transmit alert messages to SpillGuard, our bespoke web portal for SpillSens.

SpillGuard is the dedicated online portal for the monitoring and fleet management of our unique multi-level alert system.

Using Google Maps, SpillGuard delivers a detailed map interface which uses colour coding to highlight the status of each deployed SpillSens sensor.  SpillGuard is intuitive and easy to use, allowing users to assign statuses to each installation, such as “site under investigation” or “alert cleared”.

SpillGuard has a variety of other functions, including access to site statistics and the ability to forward alarm messages via e-mail or SMS.

Efficient sewer flow is critical in avoiding flooding, especially as the climate is changing and rainfall events are growing heavier.  SpillSens provides an early warning to potential hazards in sewer networks, helping to avoid flooding caused by blockages.
