Because the water level self-recording device at Dajiangkou hydrological stations of Wusijiang in Guangxi could not run normally for a long time, a low-cost and simple water level information transmission device, cable-transmission water gauge was developed.

In the frigid zone,such as Heilongjiang,Jilin and the northern part of Inner Mongolia Autonomous Region,automatic stage recording platform can not be used to get telemetric data during the flood period of spring and early summer because of long winter and low temperature,which extremely decrease the effective application of automatic stage monitoring system.
