Different silt content velocity of water flow survey devices of self -recording formula

The utility model discloses a different silt content velocity of water flow survey devices of self -recording formula, the device includes floater, inelastic connection rope, slip -ring, elastic vertical column, answers force transducer and data acquisition and recording ware, the floater is fixed on the slip -ring through inelastic connection rope, and the slip -ring cup joints on elastic vertical column, and the position on elastic vertical column can be along with water level proper motion slide control, the elastic vertical column bottom mounting is at the bottom for the force transducer that answers who detects elastic vertical column bending stress pastes the back side at elastic vertical column, answer force transducer and data acquisition and recording ware to be connected. The utility model has the advantages of simple structure, convenient to use, low in cost, can the historical velocity of flow data of automatic recording, the precision is high.
