Abstract. A method of weak magnetic fields measurement with nutation nuclear-magnetic magnetometer on the flowing liquid is considered. Technical requirements for various construction elements of magnetometer and flowing liquid parameters are defined both experimentally and theoretically. Operation of the measuring sensor has been tested experimentally with the use of the most optimal liquid medium. Further avenues for improvement of the construction and of accuracy characteristics of the developed magnetometer are formulated.
