SonTek ADP Acoustic Doppler Flow Profiler "River Investigator"

based onSonTekThe company has been tested for a long timeADPAcoustic Doppler profiler technology,“River surveyor”It has become an advanced equipment for accurate and reliable flow testing of ships during navigation. The system includes a walking typeADPProfile analyzer, bottom tracking measurement functionDGPSMeasurement interface and applicable toWindowsThe operating platformRiverSurveyorSoftware, etc.SonTekThere are several different configurations and operating frequencies of the instrument, which can be used for large rivers like the Yangtze River and Yellow River, as well as for small streams only a few meters deep. The instrument adopts a single working mode that automatically adapts to different water depths, and can measure in rivers with varying water depths or riverbed water depths. It is also reliable and stable, and the software is very convenient to use. It can be set up and put into operation in just a few minutes.

real-time measurement
River surveyors started with an easy-to-use software package. To develop and improve this software,SonTekConducted several years of field experiments. As long as you input the maximum water depth into the system settings, you can prepare for the measurement! Based on the design concept of ease of use and time-saving, the vast majority of users can learn basic measurement techniques even without detailed training.

Data processing results
The river surveyor software program allows you to view real-time collected data and use advanced menus to return and process data. Supports both imperial and metric units, while also allowing integration for each profileDGPSdata

RiverSurveyorstandard system
Based on traditional methodsSonTek ADPPlatform, this model is very suitable for deep water rivers with lower operating frequencies, and users can flexibly use it on mobile boats or fixed underwater automatic measurementsADP. StandardADPThe feature of the system is a pressure resistant aluminum alloy shell that can be easily installed on one side of the measuring vessel. Optional accessories include a sensor that automatically measures the depth of the transducer entering the water, an internal recorder, and an external battery box.

RiverSurveyorSmall scale system
10The centimeter diameter transducer probe can be easily moved and installed on one side of all ships or buoys in a small system. The small transducer probe has very little disturbance to the water flow, and can achieve ideal results even in shallow water measurements. Optional accessories include a sensor that automatically measures the depth of the transducer entering the water and a built-in rechargeable battery.

“River Cat”integrated system
“River Cat”yes“River surveyor”The flagship product in the product line. Equipped with an integrated aluminum alloy catamaran,“River Cat”Capable of measuring areas that cannot be measured by small systems, powered by built-in alkaline batteries, bidirectional wireless communication, and weighing less than12Kilogram, it can be easily towed on bridge piers, as well as behind small boats and kayaks.“River Cat”It can be easily removed from the integrated hull, and the electronic control box can be placed on other work platforms as needed; In this way,“River Cat”It can be fixed and used on the measuring ship. Similarly, any model“River surveyor”The system can also be easily upgraded to“River Cat”System.

RiverSurveyorThe software is designed by hydrological experts and can use and depict data in the format requested by users.RiverSurveyorAllow users to collect, organize, and process their own data, supporting several different output and reporting formats.

smallADPof10The centimeter diameter transducer head makes it easy to install on one side of a small boat. The disturbance of small diameter on water flow is very small, and even in shallow water, ideal results can be achieved.

“River Cat”Provided the best solution for bridge measurement. Previously, it required several people to carry bulky equipment and spend several hours working, but now it can be easily completed in just a few minutes.“River Cat”The modular design allows for easy control of systems with catamarans using on or off. optionalDGPSThe system makes it an ideal tool for measuring lakes and reservoirs.
