Buraq Integrated Solutions

The Buraq Integrated Solutions RSS-2-300WL has an integrated radar surface velocity and level meter for contactless measurements of surface flow velocity and water level. Contactless radar technology enables quick and simple sensor installation above the water surface with minimum maintenance. Calculation of the total flow discharge is internally implemented within the instrument by combining surface velocity measurement, water level measurement, and a configured cross-section of the river or channel. Defining the measurement parameters such as profile cross-section, material of the edges, location of the sensor above the water, and all other instrument settings can be easily set with the Buraq Integrated Solutions configuration application using any available communication interface.
