Claim Text:
1. A nuclear magnetic flowmeter, comprising: a measuring tube through which a multiphase medium is flowable, an upstream end of which is connectable to an inlet tube and a downstream end of which is connectable to an outlet tube, and a medium bypass connected to the measuring tube comprising a bypass tube, and at least one of an inlet valve and an outlet valve, thus wherein the flowmeter has a calibration operation mode in which the bypass tube is connected to the inlet tube and to the outlet tube and flow through the measuring tube is stopped for calibration of the flowmeter, all flow passing through the bypass tube, and wherein the flowmeter has a normal operation mode in which measurement operation of the flowmeter allows the medium to flow from the inlet tube via the inlet valve into the measuring tube and from the measuring tube via the outlet valve into the outlet tube and in which no medium by passes the measuring tube, there being no flow through the medium bypass.
