Fully Loaded, Non-Contact Discharge Measurement Radar Sensor with integrated data logger and GPRS/GSM communication. 

The RQ-30 ADMS allows a discharge measurement for rivers, streams open channels and canals where continuous monitoring is desired. Besides the advantages of the basic RQ-30 system there is additional data logging as well as data transmission (2G / 3G / 4G) integrated in the RQ-30 ADMS system. 

The sensor can be simply mounted on bridges, on the roofs of closed canals or channel superstructures. It is most ideally installed at measuring spots where continuous discharge measurement is to be done and the data logging as well as the data transmission should be integrated into an all-in-one system. It's the perfect discharge radar for flood warning.
