RG-30 Contact-free velocity sensor for open channels and rivers » Maintenance free » No structural constructions in water needed » Simple integration into existing system » Fully operating even in flood water situation » Low power consumption » Detection of flow direction » Measurement range from +/- 0.10 to +/- 15 m/s (depending on flow conditions) » Near blanking zone 0.5 m » Non-contact and fast measurement » Own measurement interval or externally triggered » Independent of environmental influence

General Introduction The flow velocity sensor RG-30 has been designed for contact-free measurements of the surface flow velocity of rivers and channels. The sensor is mounted above the channel, there it radiates the radar signal inclined about 60° to the water surface. The reflected radar si- gnals from the water surface are received, analyzed and converted into the average surface velocity. Measurement principle Measurement flow velocity The measurement of the flow velocity is based on the principle of the Doppler frequency shift. Due to the comparison of the radiated frequency and the reflected...

Functionality Contact-free = failsafe = low maintenance Due to the contact-free measurement the measurement setup is not threatened by sediments and floating refuse in the water. This results in a very low maintenance operation and an increased reliability especially on floodwater. Application The sensor impresses with its low power consumption and its high reliability. Thereby it enables the permanent recording of the flow velocity. Setting and configuration of the RG-30 can be easily and conveniently done on your PC or laptop via standard terminal programs.
