Tracer gas flow regulator for tracer gas injection system, has orifices located on positioning disk and ensuring communication between outlet of upstream circuit and inlet of downstream circuit, where orifices have equal diameter

摘要

#CMT# #/CMT# The regulator has orifices for ensuring a communication between an outlet of an upstream circuit (2) and an inlet of a downstream circuit (3). The orifices are located on a positioning disk (10) which is movable with respect to the outlet and the inlet, where the orifices have equal diameter. The disk allows a rotation of an axis passing via its center and parallel to axes of passage openings (24). #CMT# : #/CMT# An independent claim is also included for a flow regulation method for a tracer gas injection system. #CMT#USE : #/CMT# Used for being arranged between a valve of a pressurized fluid source and an end of a duct of a tracer gas injection system (claimed) for regulating a flow of a tracer gas, where the system injects the gas into the duct for measuring a flow of a fluid e.g. air, passing via the duct. #CMT#ADVANTAGE : #/CMT# The regulator has a mechanical design and does not require any power supply, so that the regulator is autonomous, flexible to use and can be installed in a rapid manner. The regulator permits to regulate the flow of the gas in a precise and reliable manner. The design of the regulator is robust and has reduced encumbrance. The regulator ensures a better distribution of the gas, and has reduced fabrication and maintenance cost. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a regulator. 2 : Upstream circuit 3 : Downstream circuit 10 : Positioning disk 21 : Upstream connection elements 24 : Passage openings.
