Abstract
A flow tube for a bidirectional flow meter includes 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. The flow tube also includes 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. The first and second flow chambers are connected in series between an inlet port and an outlet port.
