Andel FloodAlert®

Early flood warning for properties not covered by the Environment Agency flood warning service

Andel FloodAlert® is the ideal early warning system for single and multiple properties at risk of flooding through rising groundwater

The posts can be strategically positioned to give maximum warning to allow for evasive action.

Easy to install and set up, the posts transmit warnings and real-time monitoring of water levels to a cloud-based portal, accessible from any internet enabled device, with no necessity for special software. Andel FloodAlert® uses a robust, ultrasonic LoRaWAN level sensor and integrated radio, encased in a recycled, watertight and shatter-resistant outer casing, ensuring consistent reliability. The posts can be installed up to 15 kilometres from the gateway in some cases and each gateway can connect to an unlimited number of users.

 

Andel FloodAlert® Sensor

Andel FloodAlert® Ultrasonic LoRaWAN Sensor is a battery operated water level sensor with integrated LoRaWAN radio. CE Conformance and RoHS Compliant. 24/7 monitoring with up to 15km range.

The sensor is integrated inside the top part of the post and monitors groundwater levels below and inside the post. The top of the post can be removed to give access for maintenance, for example battery replacement, however batteries will last for 12 years and no routine maintenance is generally required.

Easy installation and set-up

Andel FloodAlert® posts are buried in the ground in 0.5m post holes and back-filled with gravel to allow groundwater to enter the post through rows of holes. The sensor monitors groundwater levels below and inside the post.

In many cases a single Andel FloodAlert® post will suffice, however a number of posts can also be deployed to protect a larger risk area and multiple properties.

The post is constructed from robust, 100% recycled post-industrial plastic waste with 30mm thick walls. Rows of holes allow groundwater to enter the post for the sensor to monitor the water levels.. The posts are available in grey or brown with reflective red and white strips, they are robust and easy to install.

 

 

Removable cap for maintenance such as replacing sensor batteries, no routine maintenance is required.

The sensor monitors water levels above and below ground 24/7, continually monitoring any rise or fall, sending SMS and email alerts to designated users and data to the cloud-based portal.

Three specified/tailored alert levels are set, based on a groundwater survey, above which the system sends the alerts and data about water levels.

 

The bottom third of the post is buried 0.5m below ground level in gravel filled post holes, allowing groundwater to enter the post.

Alarm levels 

Depending on ground conditions and following a groundwater survey, three alarm levels will be programmed into the system. Each time an alarm level threshold is breached, the designated property owner/s will receive email and SMS warnings. 

Gateway 

Users will be supplied with LoRaWAN gateway hardware and software as part of the network, receiving data from FloodAlert® posts and transferring the data to the cloud-based monitoring software and alerts to designated users. Indoor and outdoor options are available, specifications vary depending on installation.

Web portal

The web portal is available via any device with a web browser and provides real-time live data showing current water levels, up to the last 30 days of water levels and information about signal strength, temperature and battery life, all displayed in a graphic format.
