What is a connected level sensor?

A connected level sensor continuously measures water height and volume in a tank, then transmits the readings remotely. Unlike a mechanical gauge, it lets you monitor the reserve in real time from a smartphone or computer.

The submerged probe measures the pressure of the water column to determine the level. The device then sends readings over NB-IoT; the app uses your tank configuration to display the level and volume.

Install the device, switch it on, then configure your tank in the Tankio app. No gateway or connection to your home WiFi is needed.

Frequently asked questions

How does a connected level sensor work?

The submerged probe measures the pressure of the water column to determine the level. The device then sends readings over NB-IoT; the app uses your tank configuration to display the level and volume.

Does a wireless sensor work for an underground tank?

For a buried tank or a tank in a cellar, check NB-IoT reception at the device location. Soil, concrete and metal covers can weaken the signal. Coverage depends on the mobile network available on site.

Is a subscription required for remote monitoring?

No, access to the mobile application and alerts is completely free. No subscriptions or hidden fees. The tankio solution is designed to be accessible without recurring costs.
