A new type electromagnetic flowmeter which utilizes an alternating square wave magnetic field applied to the unopened blood vessel is described. It attains stability of baseline and sensitivity not possible with older D.C. and A.C. meters and therefore puts measurement of blood flow through the unopened vessel on a practical basis.
