Application

• Measuring tube with 150 mm diameter
• No power supply available on site

Definition of tasks

• Groundwater level measurement at multiple level measurement spots
• Data logger installed in measuring tube
• Stable and reliable data transmission
• Extremely long lifetime without the need to replace the battery
• Forwarding of measurement data to higher control system

Solution

• A battery-powered GPRS level data collector with a directly connected pressure probe Type AquaBar has been used.
• The very powerful battery and a very short measurement duration of less than 1 sec. per measurement allow a battery life of approx. 10 years.
• Thanks to very compact dimensions and the high protection degree it was possible to place the data logger directly within the measuring tube.
• Effective data compression as well as the special transmission method ensure uninterrupted transmission of readings. The connection to the customer process control system is carried out using the NIVUS data portal "Device to Web".
