title: The electromagnetic flowmeter.
abstract: The electromagnetic flowmeter, which has developed since its inception into a reliable clinical instrument that has become the standard to which all other flowmeters are compared, is described. Perivascular and intravascular transducers now available, which can easily be used to give reliable, high fidelity recordings of blood flow and velocity, are also discussed.
