Manhole fill level monitoring
Sensoneo Octopus Water Level Sensor is an enterprise-class device for remote monitoring of rising water levels. It is intended as a remote overflow warning system. It measures the water (or any other liquid) level in a manhole. It’s fully adjustable for different depths up to 25 meters. Thanks to adjustable water level indicators (tentacles), Octopus can detect up to 3 different thresholds. When the water level rises and reaches one of the water level indicators (tentacles), the system sends an immediate notification.
We design, develop and produce the sensors and all software in-house and we are proud of it.
Versatile water level monitoring
Our water level remote monitoring solution for detection of high water levels has many advantages. The water level sensors are robust, waterproof and shock-resistant, fully functional within the wide temperature range, and are set to measure from 1 to 25 meters.
The sensors can monitor any type of liquid in manholes or containers of various types and sizes. The casing complies with IP65 and the bushings comply with IP68.
Immediate warning on rising levels
Sensors detect rising water levels. Octopus water level sensor can detect up to 3 different thresholds. The thresholds are adjustable. Octopus water level Sensors can connect to GSM and GPRS to ensure fast and reliable data transfer. Payload and network communication is encrypted on two levels preventing misuse of Sensoneo Sensors for DDOS attacks.
Sustainable and resistant product design
All R&D is conducted in-house. The hardware is of high quality, making use of top quality electronic chips available. The sensors are equipped with replaceable batteries with a lifespan of several years.
Optional features are temperature measurement and external antenna.
