Low-maintenance groundwater telemetry

Reliable, Affordable telemetry

We offer multiple solutions for groundwater monitoring. The equipment can be purchased or acquired via operational lease. The groundwater level is measured using a pressure sensor and transmitted wirelessly in real-time to our dashboard. There, all measurements are securely stored for you to easily view, compare, and export.

We provide:

24/7 real-time insight

All measurements are sent directly to our secure cloud environment, where you can view them immediately. No need to go to the measurement well to retrieve measurements.

Versatile dashboard

The Blik dashboard offers a simple and clear overview of all measured values. Data can be exported from the dashboard to Excel or CSV, for example, allowing you to easily combine the data with your own data and systems.

Robust equipment

Our equipment has been developed in-house from the ground up to be robust, low-maintenance, and durable. The equipment is fully IP-68 water-resistant*, features a battery that lasts 8 years with a measurement interval of 1 hour, and a field-replaceable battery and plumb bob.

* The plumb bob can remain underwater indefinitely. The transmitting equipment is guaranteed for up to 72 hours at a depth of 2 meters.

Usable anywhere

Our solution can be deployed in any monitoring well: The digital plumb bob can be suspended up to 200 meters deep, and the transmitting equipment is compact enough to fit even in the smallest street pots. External antennas are available for reception in steel conduits.

Built for water management

Our dashboard was designed and built by Blik from the ground up. As a result, it is fully geared towards the simple and clear monitoring of groundwater. We are always open to feedback and are happy to think along with you about how the dashboard can best support you in your tasks.

Is there something missing from the dashboard? Because our dashboard is developed in-house, custom adjustments and additions are always possible.

Clear insights

See all information collected by the node (water level, barometric information, precipitation data) at a glance.

Integration with other systems

By means of an open REST API, the same data accessible via the Blik dashboard can also be automatically queried by other systems. This allows you to build connections to other systems yourself (or have them built).

We also have existing connections with various widely used systems. Do we not yet have a connection with a system you use? We would be happy to build one for you.

Efficient and clear

Purposeful and streamlined to provide a clear view of the groundwater. The first measurements can be studied* within just 1 hour of installation, and the node requires no maintenance. The entire chain consists of 1 integrated sensor/telemetry solution so that money and time can be saved.

Simple and robust

Our node is simple to use, robustly built, and can operate on a set of batteries for up to 8 years*. The node itself is placed at the top of a monitoring tube, and the digital plumb bob goes into the tube. The cable length can be specified in advance so that it always fits perfectly. Furthermore, no infrastructure is required – the measurements are received on the Blik dashboard via existing communication networks.
