Flow Velocity Measurement using Radar Technology The RG-30 measures the surface flow velocity of rivers, streams and channels by use of innovative radar technology. 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. Features and advantages 99 Non-contact and fast measurement of surface flow velocity 99 Simple mounting on bridge railings or any other superstructure accross the river 99 Low power consumption and simple...

Discharge Measurement using Radar Technology The RQ-30 is a sensor for discharge measurement of rivers, open channels and canals with known crosssection profile using innovative radar technology. It enables reliable, non-contact measurement without the need for structural work in the water. Features and advantages 99 Maintenance free 99 No structural work is necessary in the water 99 No threat to the system through flooding 99 Low power consumption enables operation using solar cells 99 Recognition of flow direction 99 Measuring range from +/-0.10 to +/-15 m/s (depending on the flow...

Stationary Measuring System Fields of application The RQ-30 enables discharge measurement for rivers, streams, open channels and canals for which continuous monitoring is desired. Thanks to the non-contact radar technology the measuring equipment is not susceptible to contamination, debris or driftwood in the water. Furthermore, the non-contact measurement warrants very low maintenance and fail-safe operation especially during high water or flooding. Implementation The sensor can be simply mounted on bridges, on the roves of closed canals or channel superstructures. The bed of the water...

Mobile Discharge Measurement with Radar Profiler The mobile measuring device RP-30 (Radar Profiler) is used to determine the velocity profile of rivers and streams. Together with cross section and water level data the discharge rate can hence be established – a highly useful measuring instrument especially during situations of high water levels or floods. Features and advantages 99 Portable mobile measuring system 99 Simple mounting on cable cranes, bridge railings or tripods 99 Suitable for flood conditions and high flow velocities 99 No threat from debris or driftwood 99 Calculation of...

Mobile Measuring System Fields of application The RP-30 is used in rivers, streams and open channels and calculates the exact discharge of the body of water through several sectional velocity measurements. As is the case with the RQ-30, this method of measurement is also based on innovative radar technology including all the advantages of a non-contact measuring device. The Radar Profiler is ideally suited for selective measurement and therefore for project evaluation or control measurements. In contrast to most other measuring devices it provides reliable values even in flood situations...

Discharge Measurement using the Tracer Dilution Method The TQ-Tracer is a mobile system for discharge measurement using a salt tracer (TQ-S) or fluorescent tracer (TQ-F). It can be deployed in rivers, creeks or waters for which data regarding the cross-section profile are not available. Here the tracer dilution method is applied as measuring principle. Features and advantages 99 Simple, mobile discharge measurement 99 Reliable results even without knowledge and independent of the cross-section profile 99 Suitable for fast-flowing, turbulent waters or where access is limited 99...

Mobile Measuring System Fields of application The TQ-Tracer system is especially suitable for fast-flowing, turbulent waters with complex cross sections, for example, mountain streams, small brooks, tributaries or even fish ladders. The measuring device is used particularly in hydrometry as well as by engineering offices, civil engineers or power plant operators, for instance for control measurements or for evaluating projects. Implementation The tracer dilution method can be applied for discharge measurement in all waters in which a thorough mixing of the tracer ensues. High turbulences,...

Discharge Measurement using a Measuring Weir Measuring weir with level logger An elementary and very simple method for determining the discharge rate of relatively small streams and channels or springs is by means of a measuring weir. Through the height of the accumulated water level the discharge quantities can be ascertained relatively accurately. In doing so, the water level is measured using a level pressure probe. Features and advantages 99 Minimum structural effort, simple measuring method 99 Discharge measurement with measuring weir; measurement of water level and temperature in...
