摘要
An automatic hydrologic parameter measuring system for a river flow comprises a supporting installed below a bridge surface; a waterproof box connected to a steel rope for suspending a weight; another end of the rope extending downwards out of the waterproof box for retaining the weight; a waterproof electric wire winding around the steel rope for transferring signals to the signal processor; a water pressure meter installed in a hollow space of the weight; when the weight being in water, the water pressure meter starts the measuring process; after the weight reaches to the riverbed, the water pressure is unchangeable; and a water pressure meter installed in a hollow space of the weight; when the weight being in water, the water pressure meter starts the measuring process; after the weight reaches to the riverbed, the water pressure is unchangeable.
