A system and method for providing a multi-double block and bleed configuration in an orifice fitting to provide an additional barrier of protection between the pressurized flow stream and the environment outside the flowmeter. The multi-double block and bleed system includes a first pair of blocking valves located below a second pair of blocking valves. The multi-double block and bleed system further includes a first vent valve positioned between blocking valves of the first pair blocking valves, a second vent valve positioned between blocking valves of the second pair of blocking valves, and a third vent valve positioned between the first and second pairs of blocking valves. The pairs of blocking valves and the vent valves are arranged to provide double block and bleed during all phases of orifice plate installation and removal.
