The flow velocity sensor is designed for non-contact measurement of the surface flow velocity of bodies of water. Radar signals reflected by the moving surface of the water are used to determine the flow velocity of the irradiated surface. Compact construction and a non contact measurement principle enable simple installation and use.
Application areas include open channels, flumes and enclosed drains. The RG-30 is especially suitable for measuring tasks where the use of conventional measuring systems is problematic, e.g. in the event of flooding.
This sensor is impressive thanks to its low energy consumption and high operational dependability. It allows continuous recording of flow velocity and, by approximation, discharge.
The RG-30 set up and parameters are assigned simply and conveniently by using a PC or laptop via our Commander terminal program.
FIELDS OF APPLICATION
The RG-30 radar sensor is used by hydrographers and water managers. It is used primarily in open rivers, streams or channels. It is especially suitable for areas where the usage of conventional contact intense measurement systems are problematic, such as measuring spots that are hard to reach or with highly turbid water. It is installed above the water and measures without direct contact to the water. The system requires no maintenance and works reliably even during high flow, flooding, despite debris, driftwood or high turbidity.
The sensor has extremely low power consumption and its high reliability for permanent recording of the flow velocity. The compact design and the contact-free measurement principle allows easy and uncomplicated mounting and usage.
The measurement of the flow velocity is based on the principle of the Doppler frequency shift. The sensor emits a radar signal and compares its frequency with the one of the reflected signal from the water surface. The frequency is shifted proportional to the surface flow velocity. Those signals are collected, evaluated and the medial surface flow velocity is determined.
