With the advancement of electronic technology, the small three-dimensional electronic compass based on fluxgate measurement principle is widely used in the navigation and orientation systems of marine instruments, underwater robots, small aircraft and other instruments and devices. Compared with the gyroscope, Small, low power consumption, zero drift characteristics. Three-dimensional vectorial measurement of flow rate is achieved by applying PNI’s TCM5 electronic compass in a three-dimensional current meter. Through the experimental verification and analysis, it is proved that the electronic compass has the characteristics of higher measurement accuracy and strong ability of resistance to hard magnetic field interference.
