There is provided a meter for measuring the flow rate of a gas along a conduit, the meter comprising a sensor assembly including a piezoelectric crystal oscillator comprising two planar tines in contact with, and extending into, said gas flow when the meter is in use, said sensor assembly being arranged: to measure the voltage generated by movement of the planar tines of said piezoelectric oscillator in the gas flow along the conduit; and to determine, from the generated voltage, the flow rate of gas along said conduit. |
