APPARATUS AND METHOD FOR DETECTING VIBRATIONS, E.G. IN A CORIOLIS MASS-FLOWMETER, USING NOISE FILTERING
摘要
<p>A process parameter associated with a material contained in a vibrating structure (3) is estimated. A plurality of motion signals (605) representing motion at a plurality of locations (5A-5D) of the vibrating structure are received. The received plurality of motion signals (605) are force filtered (1020) with a force filter (610) to produce a force-filtered motion signal (615) that discriminates motion attributable to a force of interest among a plurality of forces acting on the vibrating structure. A process parameter (625) associated with the material contained in the vibrating structure (3) is estimated from the force filtered motion signal.</p>
