The following disclosure relates to a flow rate measuring device and method capable of correcting a gradient. More particularly, the following disclosure relates to a flow rate measuring device and method capable of correcting a gradient that may measure a flow rate having a minimized measurement error by including a sensor unit provided on a bottom surface of an inner portion of a fuel tank in order to accurately measure a flow rate value remaining in the fuel tank to obtain distance information between the bottom surface of the fuel tank and an oil surface and gradient information of the fuel tank itself.

Flow rate measuring device and method capable of correcting gradient

Provided is a device for magnetizing a ring-shaped magnet for a brushless direct current (BLDC) motor, including: a rotor having a ring-shaped magnet installed on an outer peripheral surface of a rotor core; and a plurality of magnetizing yokes disposed so as to be spaced apart from each other by a predetermined interval while facing an outer peripheral surface of the ring-shaped magnet, magnetizing the ring-shaped magnet to form even-numbered unit magnets, and magnetizing the ring-shaped magnet only in regions except for one end and the other end of the unit magnets.

Device for magnetizing ring-shaped magnet for BLDC motor

Provided is an impeller for a fuel pump of a vehicle capable of decreasing a magnitude of high frequency fluid noise due to high speed rotation of the impeller by upper and lower blades of impeller blades positioned between upper and lower casings of the fuel pump and coupled to a shaft of a driving motor to deliver a fuel by rotational force so as to have asymmetrical angles based on the center of a thickness of an impeller body in sucking the fuel from a fuel tank and supplying the fuel to an engine of an internal combustion engine.

Impeller for fuel pump of vehicle

A fuel pump module, in which an in-tank filter and a fuel pump are installed at respective locations and held by a pump retainer, thereby allowing fuel to easily flow in the fuel pump module and realizing smallness and improved filtering performance of the fuel pump module.

Fuel pump module

A flange for a fuel pump module and a manufacturing method thereof, in which the passage communicating a first valve seat with a second valve seat in the flange can be easily and simply formed by inserting a passage forming piece in a mold without requiring an additional process during an injection-molding process of manufacturing the flange.

Flange for fuel pump module and manufacturing method thereof

The present invention relates to a fuel level system for an automobile, and more particularly, to a fuel level system for use in informing a driver of the amount of remaining fuel in a fuel tank of an automobile using gasoline, light oil, gas or the like, wherein a flowing electric current is increased in a contact of a level sender unit. The fuel level system of the present invention comprises a level sender unit installed in a fuel tank of the automobile, a fuel gauge, and a resistor installed inside or outside the level sender unit within the fuel level system to increase an electric current flowing through a contact of the level sender unit.
