  • Profiling float and usage of the profiling float
    Patent number: 7699677
    Abstract: Provided is a profiling float that can minutely and surely control effective buoyancy acting on the float in itself, and usage of the profiling float. The profiling float according to the present invention is equipped with a float chamber forming an airtight internal space, a fluid storage part provided in the float chamber and storing a fluid for control of buoyancy, a bladder provided at the exterior of the float chamber, in the interior of which the fluid for control of buoyancy is filled to change a volume thereof, thereby controlling buoyancy acting on the profiling float, a pump mechanism for transferring the fluid for control of buoyancy between the bladder and the fluid storage part, and a driving source for driving the pump mechanism, wherein the pump mechanism is composed of a gear pump.
