Abstract :
A new water level measuring system, using laser rangefinder sensor with phase method as laser water level sensor without cooperative target is presented. The laboratory and field experiments have been done to confirm the application field and measuring accuracy of system. The results show that the measuring accuracy could reach to ±1.5 mm in calm water in case that water turbidity value is greater than 300 NTU. Furthermore, the measuring accuracy can reach to ±3mm for the measuring period taking 5 minute in case of the water surface sloshing. The maximum measuring distance of system could reach to 12m.
