Patent number: 9816846Abstract: System and methods for determining a non-condensable gas parameter relating to the amount of non-condensable gas within a variable flow rate fluid flow containing both non-condensable gas and condensate are disclosed. An apparatus may include a measurement tube for receiving the fluid flow and arranged such that the fluid flow through the measurement tube comprises alternating sections of non-condensable gas and condensate; a flow sensor for generating a flow rate signal relating to the flow rate of the fluid flow in the measurement tube; a phase sensor for monitoring over time the alternating sections of non-condensable gas and condensate flowing through the measurement tube and arranged generates a phase signal characteristic of the said sections monitored; and a non-condensable gas determining unit configured to determine a non-condensable gas parameter relating to the amount of non-condensable gas in the fluid flow based on the flow rate signal and phase signal.Type: GrantFiled: September 19, 2014Date of Patent: November 14, 2017Assignee: Spirax-Sarco LimitedInventors: Nashtara Islam, Peter Usher, Ben Frisby, David Oliver

Patent number: 9588083Abstract: A method of determining the phase compositions of a multiphase fluid flow in a fluid line, including obtaining a vibration signal from the fluid flow using a vibration sensor comprising a target disposed in the fluid flow which vibrates in response to fluid flow in the fluid line. The vibration signal is analyzed to determine a first energy parameter which is related to the energy of the vibration signal within a first frequency band, and a second energy parameter which is related to the energy of the vibration signal within a second frequency band; and a phase composition parameter, such as a dryness parameter, relating to the phase compositions of the fluid flow is determined using the first and second energy parameters. An apparatus for determining the phase compositions of a multiphase fluid flow in a fluid line.Type: GrantFiled: September 13, 2013Date of Patent: March 7, 2017Assignee: Spirax-Sarco LimitedInventors: Ben Frisby, Nashtara Islam, Peter Usher, Mitchell Kane

Patent number: 9285255Abstract: 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.Type: GrantFiled: January 23, 2015Date of Patent: March 15, 2016Assignee: SPIRAX-SARCO LIMITEDInventors: Nashtara Islam, Ben Frisby, Grant Needham
