摘要: A flow tube for a bidirectional flow meter comprises a first means (for example in the form of a first flow chamber) for generating a periodic pressure fluctuation whose frequency varies in dependence on the flow rate of fluid through the meter in a first direction; and a second means (for example in the form of a second flow chamber) for generating a periodic pressure fluctuation whose frequency varies in dependence on the flow rate of fluid through the meter in a second direction, opposite to the first direction;wherein said first and second generating means are connected in series between an inlet port and an outlet port.

摘要: The present invention relates to a fluid flow meter, comprising: means for defining a fluid flow path; a rotor, with at least one blade, positioned in said fluid flow path; and a ring positioned upstream from, and adjacent to, said rotor; wherein the ring is adapted to conditions the flow at the leading edge of the rotor blade over a range of operating conditions. By providing a ring the accuracy and flow measuring range may be improved.

摘要: An electromagnetic flow meter is configured as an insert for insertion into an in-situ housing connected in a flow line. This can enable a body previously installed for use with an insert of a mechanical flow meter to be adapted for use with an insert of an electromagnetic flow meter without having to disconnect the body from a mains supply.
