[0002] The lead weight is a crucial platform for carrying instruments and equipment in hydrological cableway surveys, primarily used for measuring parameters such as velocity, depth, and sediment content at cross-sections of rivers and canals. The underwater signal source is a vital instrument for transmitting underwater signals during hydrological cableway surveys; it is typically mounted on the tail fin of the lead weight and is mainly powered by dry-cell batteries. The underwater signal source also connects to other instruments on the lead weight via cables, such as velocimeters and bottom switches.
