Overview
The movable parts that cannot be blocked are not affected by the movement of the seabed and GPS signals, with high precision and an accuracy of over 1%. The measurement time is 5-20 minutes, providing accurate seabed shape detection. It is very suitable for narrow areas with steep slopes and fully enclosed systems. It can be used for various weather conditions. The exterior of the three body ship has no protruding parts, low center of gravity, and is not affected by external waves. It can be operated using a PDA. The Bluetooth effective range is large, and the operator does not have to stand in Hanoi to directly calculate the flow measurement principle. OTTQliner2 is suitable for measuring small and medium-sized natural rivers as well as artificial channels. Tong

measuring principle
OTT Qliner2 is suitable for measuring small and medium-sized natural rivers as well as artificial channels. Through PDA for convenient and effective control, it is possible to quickly measure the fixed-point flow velocity, cross-sectional flow velocity distribution, and cross-sectional flow rate of rivers.
Qliner2 itself is a small acoustic Doppler flow measurement system that uses ultrasonic sensors on a small boat to measure cross-sectional flow velocity in the river channel. The operator uses a PDA to connect the sensor via Bluetooth, and the data can be analyzed and stored in real time.
The sensor uses four acoustic beams to monitor cross-sectional flow. As shown in the figure below, beam 1 and beam 2 are at a 25 degree angle to the vertical direction respectively, used to measure the flow velocity on the vertical line, and beam 4 is vertically downward, used to measure the position and water depth of the seabed; Beam 3 is used for compensating shallow water flow velocity.
During the use of Qliner2, users need to first determine the vertical line of the river section, use ropes to drag the small boat along the determined route, and stay at each vertical line for 30 seconds to 1 minute to obtain stable and accurate measurement results. Typically, section measurements can be completed within 5-20 minutes with an accuracy of over 1%.
