Abstract
A valve used in combination with a vessel containing fluid in the interior and a parameter measuring device. The valve allows the device to be exposed to the fluid in the interior of the vessel. The device may be installed into the valve, and the valve may be fitted to the side of the vessel. The valve improves upon other prior art by providing provisions for purging air trapped in the internal cavity of the valve. The valve includes a purge position, which provides a smaller opening from the interior of the vessel to the internal cavity and an air path to the external atmosphere. Fluid may fill the valve pushing trapped air out of the valve until the majority of the trapped air is expelled.
