Station design, fabrication and installation
ALS designs and supplies a wide range of products for the unattended, long term, continuous measurement of water level and flow suitable for flood warning systems.
By selecting and integrating the best sensors for individual applications from a range of suppliers, ALS is able to offer specialised solutions tailored to client requirements and budgets.
Professional installation, maintenance and record keeping of long term automatic stations ensures the most reliable records are collected and stored. ALS Hydrographics has a strong record in long term monitoring projects.
Our systems and services can be delivered in real-time via a number of methods such as integration into existing SCADA systems, email, sms or our online data portal.
Our systems can also be integrated into a flood warning network and public information signs. We are able to provide live video feed or still pictures to the internet for either public viewing or password protected portal.

Harbinger ALS
Hydrographics has developed the Harbinger Advanced Flood Warning System and that is good news for people who need to react to wet weather events quickly.
The Harbinger system models storm and flood predictions hours in advance, creating vital lead time for critical safety responses.
Instead of waiting for the storms and floods to arrive, the ALS Harbinger System utilises radar imagery and ground referencing from hydrometric monitoring stations to provide storm and flood forecast information on the fly for those who need to know ahead of time.
Data management
Accurate and reliable data is an essential. ALS provides a wide range of data management systems and services to complement its range of measurement devices for the automated, long term, continuous management of data from nearly any system, including weather, air quality, water, wastewater or geotechnical systems.
