Abstract

The basic aspect of the invention is a double base mounted measuring unit consisting of A structure consisting of an outlet gas pipe and an inlet gas pipe connected to a ball valve. Basic characteristics have layers One with a first circuit connected in parallel with a second circuit. The first and second circuits consist of valves. The first butterfly valve is connected in series with the first filter and the first pressure regulating valve. The second stage is connected to the first stage at one end and to the outlet gas pipe at the other end. The second layer consists of flow meters connected parallel to the bypass. where the flow meter has an intake pipe of another nature The total pressure relief valve can have pressure relief in the range of 0.52 percent. Each pressure control valve can also have a total pressure relief valve. and the intake pipe of the meter The flow rate can be shortened to 4D to reduce the volumetric area of the base mounted measurement unit.
