For the stable supply of drinking water.
The Dutch public enterprise WMD Drinkwater is monitoring groundwater extraction using the KELLER DCX-22AA groundwater data logger. The evaluation points for the DCX-22AA by WMD Drinkwater are:
1. The best cost-performance ratio
2. The barometric correction system is very simple and convenient
3. All functions are overwhelmingly user-friendly, and linking the serial number with the installation location is easy.
Barometric correction is performed by a second pressure sensor within the communication unit. The DCX-22AA is equipped with real-time barometric correction functionality, making it suitable for purposes such as groundwater level measurement and sewage overflow detection. The entire sensor is waterproof (IP67), so there is no problem even if the measuring tube gets flooded.
Since the PC connection part of the communication unit is located at the top of the measuring tube, there is no need to remove the tube when reading data. This allows for real-time monitoring of measurement data and easy comparison with manually measured values. The barometric correction feature eliminates the need for additional air pressure loggers for installation and reading, as well as manual barometric correction, simplifying system operation.
