Solar Powered Tank Monitor
Level, temperature and overflow monitoring for tanks with no power and no network.
The product
Continuous power with no cable
The monitor is powered by two 18650 rechargeable batteries, charged by a solar panel, giving continuous power with no need for a cabled power source. The unit uses a GSM module to provide a network connection to the AGAD Portal.
To save power, the unit powers up the sensors at an interval, takes a reading and then transmits to the Portal. It can be used to monitor parameters on a tank — for example temperature or level — and has four digital inputs for events or alarms such as door open, tank high level or bund high level.
“Ideal when no site power or network infrastructure are available.”Gerard Shaw, Director, Listo Ltd
