The ultimate, portable system for shallow water discharge measurements
Single plane, narrow beams give accurate data close to the edges
Easy to use PDA software
Uses USGS approved discharge algorithms for moving boat measurements
Fully enclosed boat runs from standard batteries
Uses high power BlueTooth® wireless communication
The Qliner allows you to measure discharge in shallow rivers and channels quickly, accurate and safe. It gives you detailed information about the river flow and you get the results immediately. Although ideal for rivers 1-30 m. wide and 0.3-5 m. deep, it is well suited for larger rivers as well. Measurement may be taken from a bridge as shown here, but the boat is also supplied with two pieces of rope to position the boat in a river from the edges.
The Qliner uses Doppler technology to measure the vertical velocity profile and the depth in a user-selectable number of sections across the river. The on-line software estimates the discharge by combining the velocity and depth information and you have the final answer by the time you have completed the data collection. The Qliner system consists of a Doppler current profiler, a boat to hold the current profiler and the Bluetooth transmitter, a watertight PDA with Bluetooth and the necessary 'Qliner for PocketPC' software.
Software
The software included monitors and controls the measurement, makes the calculations and exports summary data to a desktop computer. The software runs on any PDA with Windows Pocket PC. All data may be reviewed and re-processed using the supplied 'Qliner Review' programma voor Windows
