Tank monitoring in Belgium:
Which connected solutions are available?

flag 1. Why Belgium is a distinctive market

Belgium has characteristics that make it a distinctive market for tank monitoring.

An exceptionally large number of tanks

• Rainwater tanks are common in Belgian homes.
• Underground tanks are often difficult to check without opening the access hatch.
• Thousands of Rainwater tanks (ii) the creation of a network of small and medium-sized enterprises.
• One connected equipment rate still weak, offering enormous growth potential.

Regulatory specificities

Belgium imposes strict standards for tanks (e.g. leak detection, periodic monitoring) and encourages energy transition through bonuses. Connected monitoring fits perfectly with these requirements. Learn more about obligations in our FAQ on connected gauges.

home 2. Tankio: the Belgian connected solution

Tankio is a 100% Belgian connected monitoring solution designed and manufactured in Belgium. Unlike many competitors importing generic products, tankio was developed specifically for the Belgian market.

What Makes Tankio Unique

• Made in Belgium: design, assembly and support from Belgium.
• LoRa + WiFi gateway: the sensor sends long-range readings to the included gateway, which uses the building’s WiFi for internet access.
• Designed for water: hydrostatic-pressure measurement and a LoRa link to the included WiFi gateway.
• More than 3 years of battery life: high-capacity battery and ultra-low-power electronics.
• Application in French: interface designed for Belgian users.
• Local support: telephone and technical assistance in Belgium, in French.

compare 3. Comparison with competing solutions

Several tank monitoring solutions are available in Belgium. Here is an objective comparison of the main options.

Why tankio stands out

Tankio stands out through a clear architecture: the probe measures hydrostatic water pressure and sends the data over LoRa to the included gateway. The gateway then connects to the building’s WiFi to feed the app, with no public LoRa network subscription.

Imported generic sensors may seem attractive in terms of price, but their reliability, safety and compatibility with Belgian standards are often inadequate. Without local support, if something goes wrong, you are alone.

handshake 4. The advantages of choosing a local product

Choosing a Belgian-made solution such as Tankio offers practical benefits that go beyond supporting the local economy.

Technical support in French

Do you have an installation problem? A question about your application? With tankio, you join a team based in Belgium, which speaks French and knows local specificities. No chatbots, no call centres around the world.

Warranty and compliance

Tankio products comply with existing European and Belgian standards. The warranty is managed locally, without having to return the product abroad. In the event of a defect, the replacement is quick.

Local economy and employment

Each tankio sensor sold participates in the Belgian economy: local design, local assembly, local jobs. It is a responsible choice that makes sense.

Adapted to the Belgian market

tankio has been designed for Belgian tanks: standard shapes, common opening diameters, compatibility with local standards. No hazardous adapter, no approximate compatibility.

"I chose tankio because it is Belgian and the support is in French. When I had a question about the installation, I had a real technician on the phone in five minutes. — Sophie, tankio user in Liège.

gavel 5. Points to consider for a water installation

Requirements for a water installation vary by region, municipality and building. A connected gauge makes monitoring easier, but it does not replace tank maintenance or any checks required for your installation.

Good practice for a water tank

• Keep networks separate: rainwater must not be able to contaminate the drinking-water network.
• Protect access points: secure the hatch, overflow and openings against falls and debris.
• Maintain the installation: check filters, pump and connections according to the manufacturer’s instructions.
• Check local rules: ask your municipality or a qualified professional if in doubt.

How tankio helps you

Connected supervision is not a legal obligation, but it greatly facilitates compliance:

• Early detection of anomalies (abnormal consumption, sudden change in level).
• History of data to prove maintenance and follow-up.
• Alerts in case of suspicious variation that may indicate a leak.
• Peace of mind, especially for second homes.

star 6. Use cases in Belgium

Here are three common situations in which connected water-tank monitoring provides useful information.

Underground water tank

The level remains visible without lifting the access hatch. A low-level alert gives time to limit use before the pump runs dry.

Garden and toilets

Level monitoring helps reserve rainwater for priority uses and prepare for a dry period.

Tank far from the router

The sensor communicates over LoRa with the gateway in the house; only the gateway uses WiFi to reach the internet.
