Patent number: 10619795Abstract: The present invention provides a monitoring apparatus for an outlet of a vessel storing gas under pressure. The monitoring apparatus comprises a flow control valve movable to a position between a fully open position and a fully closed position to adjust a flow of gas from the outlet of the vessel, a valve position detector connected to the flow control valve to detect the position of the flow control valve, an internal pressure sensor to sense an internal pressure Pint(t) of the gas in the vessel at different times, a processor, a memory and an alarm. The processor calculates an actual rate of change in pressure dPint/dt of the gas in the vessel over time, and compares dPint/dt with an expected rate of change.Type: GrantFiled: December 8, 2016Date of Patent: April 14, 2020Assignee: LINDE AKTIENGESELLSCHAFTInventors: Piers Lambert, Rigoberto Perez De Alejo Fortun, Helmut Franz

Patent number: 10508772Abstract: The present invention provides a flow apparatus (10) having a flow control valve (12) having a housing (14), an aperture (16), an aperture obturator (18) and an actuator (20) for moving said obturator (16) between a first closed position and multiple open positions (B-L), characterised by a valve position monitor (21) for monitoring the position of the valve (12) and comprising a plurality of discrete sensors (28a to 28e) associated with a plurality of open positions (B-L) of said valve for monitoring the presence or absence of one or more members (26) movable with said valve (12). The arrangement may be used to monitor the valve position and such monitoring may be of use in the prediction of the amount of fluid remaining within a cylinder (32) to which it has been attached.Type: GrantFiled: November 3, 2016Date of Patent: December 17, 2019Assignee: LINDE AKTIENGESELLSCHAFTInventors: Michael John Cox, John Andrew Golby, Alan Edward Green, Piers Lambert
