Radar flow meter RG-30

for waterIP67open-channel

The flow velocity sensor RG-30 has been designed for contact-free measurements of the surface flow velocity of rivers and channels by means of radar technology. Features and advantages - Maintenance free - No structural work is neccesary in the water - Simple integration into existing systems - No threat to the system through flooding - Low power consumption - Recognition of flow direction - Measuring range from +/- 0.10 to +/- 15 m/s (depending on the flow conditions) - Near blanking zone 0.5 m - Non-contact and fast measurement - Own measurement interval or externally triggered - Independent of environmental influences Fields of application The radar sensor RG-30 is used by hydrolography and water management. It is applied for example in open rivers, streams or channels. It is especially suitable for measurement tasks where the usage of conventional respectively contact intense measurement systems is problematic. As for example at measuring spots which are hard to reach or carry highly turbid water. It is installed outside the water and measures without direct contact to the same. Hence, the system requires no maintenance and works reliably even during high flow, floodings or despite of debris, driftwood or high turbidity. IMPLEMENTATION The sensor impresses with low power consumption and its high reliability for permanent recording of the flow velocity. The compact design and the contact-free measurement principle by means of radar technology allows easy and uncomplicated mounting and usage. MEASURING PRINCIPLE The measurement of the flow velocity is based on the principle of the Doppler frequency shift. The sensor emits a radar
