摘要：A flow meter for the registration of pulsating liquid flows, and preferably forregistration of small blood flows. The flow is measured by means of a differential
pressure measurement over a first flow resistance (I) having a resistance R.sub.1. The flowmeter includes a high pressure part in the form of a flow resistance (II) and a lowerpressure part in the form of a flow resistance (III), and these have the resistances R.sub. 2and R.sub.3, respectively. The resistances R.sub.1, R.sub.2 and R.sub.3 are selected so as toadjust the pressures on each side of the differential pressure meter in phase with eachother independent of the frequency of the flow pulsations. Each resistance has acorresponding modulus of elasticity, and the resistances and moduli of elasticity are sorelated as to fulfill certain formulas.
