## Abstract

A fluid production computation apparatus using the electromagnetic induction theory is disclosed. In accordance with an embodiment of the present invention, the fluid production computation apparatus includes a line through which a current flows according to fluid production; a magnetic sensor, measuring magnetism induced by the current; and a fluid production computation unit, computing the fluid production through magnetism measured by the magnetic sensor. The conventional flow measurement apparatus measures the flow by measuring a current or a voltage induced by magnetism formed by a fluid or by using a fluid measurement sensor. However, with the present invention, an apparatus can be miniaturized and the measurement can be precisely performed by measuring a magnetic field induced by a current flowing according to fluid production.
