Claim 9:
10. The method according to claim 1, wherein the abrasive particles are magnetic abrasive particles,
wherein the method further comprises:
activating a magnetic field in the first and/or second channel during a time interval such as to cause a local accumulation of magnetic abrasive particles in said first and/or second channel that results in a pressure pulse within that channel, and
subsequently, deactivating said magnetic field,

wherein said activation and deactivation are repeated to create a series of pressure pulses over time, of which the amplitudes and timings are determined such that said series of pressure pulses represents one of said downhole measurements for use in a mud pulse telemetry system.
