Remote Ground and Surface Water Level Monitoring

The impacts of global climate change are especially striking when talking about “water” in general. On the one hand, ground water has become a diminishing resource – on the other hand, we are facing more and more extreme weath-er events, such as severe flooding and storm surges. These issues bring great challenges to us.

APPLICATION

In order to face global responsibility in this regard, global networks for level monitoring of ground and surface water are established.
These will help to guarantee flood protection for waterways and in coastal regions and will furthermore ensure drinking water sourcing for private homes, for industry and for agricultural purposes.
Network operators are private and public water service providers as well as government authorities and municipal administrations. Since the places of installation are numerous and far apart from one another, an independent power supply as well as wireless data transfer
(e.g. via LoRaWAN®) are necessities.

The technical requirements to level sensors are quite wide-ranged:

  • Precise hydrostatic level measurement
  • High long-term stability
  • Integrated temperature measurement
  • Low power consumption
  • Compact design

IMPLEMENTATION

BD|SENSORS’ solution is a hydrostatic level probe with the following characteristics:

  • Highly accurate piezoresistive stainless-steel pressure sensor
  • I²C interface providing pressure and temperature
  • Min. power supply voltage 2.7 V
  • Housing diameter only 19 mm
  • Current consumption < 1 mA during measurement  / < 50 µA in sleep mode

With this level probe, BD|SENSORS makes a significant contribution to the long service life and reliability of battery-powered data acquisition systems.
