Claims

[Scope of utility model registration request]

A wire with a weight attached to the tip is fed out one after another, and when the weight reaches the liquid level, the weight reduction of the weight is sensed, the feeding of the wire is stopped, and the height of the liquid level is measured from the length of the fed out wire. In a depth sounder, the bottom hole of the sounder frame is attached closely to the upper opening of the tank, and an intermediate ring passing through a wire is attached to the bottom hole so as to be slidable in the vertical direction. A depth sounder characterized in that a bottom opening is sealed by a weight being lifted up, and the bottom opening follows and rises, activating a switch that regulates the lifting limit of the weight.
