Abstract:
A nuclear magnetic resonance flowmeter comprising at least one coil ( 40 ) of electrically conductive material through which an electrical current flows when the apparatus is in use. This generates a magnetic field in a region through which flows a fluid the flow of which is to be measured and throughout which there is a uniform weak magnetic field such as the Earth's magnetic field. Electrical circuitry ( 46  to  52 ) is connected to the said at least one coil ( 40 ) to switch on and abruptly switch off such an electrical current. There is an NMR sensor ( 42 ) connected to the electrical circuitry ( 46  to  52 ) to provide a measure of the decay in the NMR signal from nuclei within such fluid following the abrupt switching off of such an electrical current. A processor ( 52 ) of the electrical circuitry ( 46  to  52 ) is formed and/or programmed to provide a measure of the flow of such fluid from the said measure of the decay. Also, a method of measuring the flow of a fluid using such a flowmeter.
