DERiver level
Safe from floods
Due to climate change, extreme precipitation events which often cause heavy flooding are occurring more and more frequently. In order to be able to monitor the height of river levels timely and accurately, reliable sensors are an absolute necessity. Different measuring principles are used, depending on the application.
Hydrostatic pressure transmitters or guided microwave sensors are often deployed in classic sounding pipes. Non-contact radar sensors are especially suitable for mounting on existing sounding pipes or under bridges.
River level measurement
The radar sensor VEGAPULS WL 61 is the ideal solution for level measurement outdoors or in sounding pipes. This compact sensor (protection class IP 68) offers a wide variety of mounting options and can be easily integrated into existing structures – this reduces installation costs considerably.
The hydrostatic suspension pressure transmitter VEGAWELL 52, is particularly suitable for use in existing sounding pipes. Its robust ceramic CERTEC® measuring cell is very reliable, remaining fully functional even when covered by crustacion deposits or sediment.
The guided microwave sensor is an interesting solution for applications in which existing mechanical sensors are to be replaced. VEGAFLEX 61 reliably detects the surface of the water without being affected by other installations in the sounding pipe.
