tankSensor PRO

“BleBox tankSensor PRO” is a smart WiFi-enabled sensor designed for measuring tank fill levels and liquid column height.

It is also possible to convert the fill level into the volume of stored liquid.

Thanks to the free wBox app, available for smartphones (Android, iOS) and computers (Windows, macOS), you can monitor real-time data from multiple sensors simultaneously.

Collect rainwater and utility water in household tanks or IBC containers.

With the “BleBox tankSensor PRO”, you can remotely check how much water you have available. Plan your garden watering, surface cleaning, and other tasks around your home, knowing exactly how many liters or m³ of water remain in the tank.

Monitor your septic tank fill level remotely, without having to open or inspect the tank!

Thanks to the precise measurements provided by the “BleBox tankSensor PRO”, you can check how full your tank is, expressed as a percentage, at any time.

This makes it easier to determine when your septic tank is approaching its capacity, allowing you to schedule septic tank emptying well in advance with a waste removal company – without having to book the service at the last minute and incur additional charges for collection on holidays and non-working days!

Example of a service that septic tank emptying companies can offer their customers:

• For customers: convenient, remote monitoring of septic tank fill levels
• For septic tank emptying companies: the ability to implement an automated septic tank emptying request system

Remote fill level monitoring and notifications make it easier to organize regular septic tank emptying services. Septic tank emptying companies can continuously monitor fill levels in their customers’ tanks, allowing them to better schedule collections and optimize vehicle routes. This means fewer unnecessary inspections, more efficient work organization, and savings in both time and costs.

Customers benefit from greater convenience and no longer need to keep track of when to schedule septic tank emptying themselves.

The device enables water level monitoring in various retention reservoirs and natural bodies of water.

Monitor water levels in:

• lakes and fish farming ponds
• backyard garden ponds
• swimming pools and aquariums
• rivers, streams, creeks, ditches, and canals

Measurements can support early warning systems, such as detecting rising water levels that may lead to rivers or streams overflowing their banks, as well as monitoring low water levels to help protect wildlife and their habitats.

“BleBox tankSensor PRO” is available in two variants:

• Standalone device that allows you to connect any compatible pressure probe ( probe not included)
• Ready-to-use kit with a submersible hydrostatic pressure probe blebox tankProbe500

The ability to choose your own pressure probe with a suitable measurement range allows you to adapt the “tankSensor PRO” to various applications – from small tanks to large technical, agricultural, and industrial storage tanks.

The device can work with submersible probes, as well as appropriately selected pressure sensors installed outside the tank, for example, at a connection located near the bottom of the tank.

The “tankSensor PRO” allows you to configure the density of the measured liquid, making it suitable for monitoring the levels of various substances, including fresh water, salt water, wastewater, as well as drinking water*, milk*, cooking oil*, heating oil*, and gasoline*.

*Measurement requires a properly selected probe that is compatible with the device and suitable for the properties of the measured liquid. The probe may require appropriate approvals or certifications (e.g., certification for food contact or for use in potentially explosive atmospheres).

In the wBox app, you can view historical data on tank fill levels and liquid column height.

Historical data is available for up to 12 months and displayed as an interactive chart, making it easier to analyze changes over time.

This allows you to:

• estimate water consumption and plan septic tank emptying frequency,
• detect potential leaks from septic tanks or rainwater storage tanks,
• check how much water has accumulated in the tank during rainfall,
• monitor water levels in garden ponds, lakes, streams, rivers, and creeks.

For advanced users, data can be exported to a file in “.csv” or “.xlsx” (Excel) format. The exported data can be used for custom analyses, report generation, or long-term measurement data archiving.

The device can send push notifications directly to your smartphone, so you don’t have to remember to regularly check the tank level.

Notifications can be triggered when values rise above or fall below a specified threshold for:

• tank fill level (%)
• liquid column height (cm)

Examples of notifications:

• “Warning: Septic tank is 80% full”
• “Alert! Septic tank is almost full!”
• “Septic tank has been emptied”
• “Water level in the rainwater tank has dropped below 10%”
• “Water level in the garden pond has dropped below 30 cm”
• “Warning! Water level in the stream has exceeded 110 cm”

The smart WiFi sensor “BleBox tankSensor PRO” also allows you to create home automation scenarios.

Based on the tank fill level expressed as a percentage or the liquid column height, you can not only generate notifications but also wirelessly control other devices equipped with BleBox controllers.

When combined with controllers from the switch family (switchBox, switchBox DIN, switchBoxDC, switchBoxT PRO), you can implement various automation scenarios, including:

• Flood protection: automatically activating a pump to remove water from a sump pit or basement.
• Pump dry-run protection: automatically switching off an irrigation pump when the water level in a well drops below a specified threshold.
• Automatic water replenishment: controlling a solenoid valve to refill water in a garden pond, aquarium, or industrial process tank.

BleBox “tankSensor PRO” features a weather-resistant enclosure and an external Wi-Fi antenna.

Thanks to the external antenna, the device can operate reliably even at considerable distances from a router or access point, including locations where the Wi-Fi signal may be weak or unstable for controllers equipped with internal antennas.

The antenna connector also allows you to replace the standard antenna with a directional antenna or position the antenna away from the device’s installation location, for example, outside an electrical distribution cabinet, metal pole, or another device’s enclosure.

BleBox WiFi controllers and sensors offer three ways to communicate:

• Directly – via an encrypted WiFi network created by the device
• Locally – through your home WiFi network, without requiring Internet access
• Remotely – from anywhere in the world via the free BleBox cloud

This solution provides:

• Local communication that remains operational during Internet outages
• The ability to operate devices without access to the cloud or Internet
• The ability to connect to the device even if the Internet connection, router, or WiFi access point fails

Thanks to the free BleBox cloud and the wBox app, you can monitor, control, and manage access to BleBox devices and sensors from anywhere in the world.

You can easily share access to your sensor with other users – family members, colleagues, or your customers.

BleBox cloud servers are located in the European Union, the USA, and Canada to ensure greater reliability and privacy.
