  • Floating body flowmeter
    Patent number: 7444886
    Abstract: A floating body flowmeter having a measuring tube (1) which is positioned vertically and through which a substance (2) to be measured flows, in which tube a floating body (3) is arranged in order to determine the flow rate, the rise height (h) of said body relative to the measuring tube (1) being in a defined relationship with the flow rate, it being possible for the measuring range to be adjusted at least via the density of the floating body (3), and the floating body (3) being heterogeneous in such a way that the latter consists of an industrial mass-produced material in the core (4), the material selection being coordinated with the fact that the measuring range can be adjusted substantially via the density of the core (4), and the core (4) is provided with an external coating (5), its material being coordinated with the fact that this is chemically and/or mechanically resistant to the substance to be measured, and furthermore that all the other parts in contact with the substance to be measured are coated
