Abstract: A device for isolating, accumulating, indicating and venting gas in a fluid system pipe includes a coupling affixed to a system pipe. The coupling includes an isolation valve. A standpipe is attached to the coupling. The standpipe holds a float trapped between a flow retaining orifice and a closed upper end save for an angled hole therein that allows gas to flow around the float. An indicator exterior to the pipe indicates the float's level in the standpipe regardless of system pressure changes. A vent valve attached above the standpipe allows controlled ventilation of the gas flowing from the system pipe through the standpipe and through the vent valve. Accumulation of gas from the system pipe lowers the float in the standpipe, at which point the user vents the gas, causing the float to rise with the rising fluid level.

Abstract: A device for accumulating, isolating, indicating and venting accumulated gas in a fluid system pipe includes a main pipe fitting affixed to a system pipe in which a hole has been drilled. A standpipe attached to the pipe fitting houses a magnetic float. A magnetic-float level indicator exterior to the pipe indicates the magnetic float's level. A valve attached to the standpipe above the magnetic float allows controlled ventilation of the gas in the standpipe and thus in the piping system. Gas from the system pipe accumulates in the standpipe, removed from the primary fluid flow path of the system pipe. In the standpipe, as the liquid/gas interface drops, the float drops to a pre-determined level, at which point the user vents the gas from the piping system, causing the magnetic float to rise indicating that gas is again at acceptable levels in the piping system.
