Abstract :
Magnetic flux is the basic magnetic quantity. The measurement uncertainty of fluxmeter is usually several parts in 104. This paper proposes a new approach of magnetic flux measurement by measuring the flux difference between rectangular pulse synthesized with a binary Josephson system and the flux under test. Experimental results show that the flux measurement repeatability is several parts in 106 which is a great improvement of flux measurement.
