RG-30

VELOCITY RADAR RG-30 / RG-30A

Descripción

Descripción

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
