Register events & react

A suitable measurement interval is crucial to avoid measurement errors. Only if you detect an event in time can you react appropriately.

The water rises rapidly within a few minutes during heavy rain and can level off again just as quickly. A measurement interval of 5 minutes may mean that you do not notice the increase at all. Reducing the interval (for example to one minute), you minimise the probability of missing an event.

Stable data transmission

In shafts or ducts, mobile radio transmission can become a challenge. Therefore, it is recommended to ideally place the transmission unit under the manhole cover (in the sand or dirt trap). However, the measuring point itself is much deeper in the sewer.

For this reason, the radar sensor is separate from the transmission unit and connected wirelessly. This allows the radar sensor to be easily positioned up to 20 metres away from the transmission unit.

Maximise measurement precision

The measuring range of up to 5 metres with a resolution of 1 mm is perfect for level measurement. The narrow opening angle of only 4° enables focused and reliable measurements. This low beam angle ensures precise measurement accuracy, especially in narrow shafts and sewers.

To avoid possible parallax errors during installation, the radar sensor has an integrated spirit level. This avoids falsified measurement due to height differences.

10 seconds measuring interval,
10 years battery life

The energy consumption strongly depends on the measuring and transmission interval. The radar sensor only needs 0.6 μWh to send a measured value to the central data acquisition system. In comparison, comparable industrial sensors require more than two hundred times as much, namely 125 μWh.

The measuring interval of the radar sensor is flexibly adjustable. With a measurement every 10 seconds, the battery life is an impressive 10 years.
