  • Flow meter
    Patent number: 9285255
    Abstract: Disclosed aspects relate to a flow meter comprising a flow target arranged to be disposed in a fluid flow path in a conduit; a beam coupled to the flow target and arranged to extend outside of the conduit; a sensor having a moveable sensor part coupled to the beam at a position which in use is outside of the conduit, and a static sensor part, wherein displacement of the moveable sensor part with respect to the static sensor part generates a signal. In use, fluid flow acting on the flow target causes displacement of the moveable sensor part, thereby generating a signal which is representative of the fluid flow rate.

  • METHOD OF DETECTING SLUGS OF ONE PHASE IN A MULTIPHASE FLOW
    Publication number: 20110137584
    Abstract: A method of detecting the presence of a slug of condensate in a conduit carrying a saturated steam comprising using a flow meter to provide an output signal representing mass flow rate of the saturated steam through the conduit; determining the rate of change of the output signal; and generating an alert in response to a predetermined profile of the output signal, when the profile includes a rate of change of the output signal falling outside a predetermined range.
