Patent ID: 8863820

Claim:
A measurement device in combination with a heat exchanger, comprising: a heat tracer sensor; a three-way valve; said three-way valve includes a retrieve port, a chamber port, and a launch port; a plastic chamber; said chamber port of said three-way valve being connected to said plastic chamber; said heat exchanger includes an inlet conduit, an outlet conduit, and an intermediate conduit interconnecting said inlet and outlet conduits; said heat exchanger includes fluid forced through said inlet conduit, said intermediate conduit and said outlet conduit, and, said fluid has a temperature; an inlet Y strainer interposed in said inlet conduit of said heat exchanger and said launch port of said three-way valve being interconnected with said inlet Y strainer, said Y strainer guiding said heat tracer sensor into said inlet conduit; an outlet Y strainer interposed in said outlet conduit of said heat exchanger and said retrieve port of said three-way valve being interconnected with said outlet Y strainer, said Y strainer guiding said heat tracer sensor into said outlet conduit; said heat tracer sensor travels through said inlet conduit, said intermediate conduit and said outlet conduit of said heat exchanger measuring and storing said temperature of said fluid as a function of time, and said heat tracer sensor being selectively isolated in said plastic chamber; a control station; and, said control station communicates with said heat tracer sensor and extracts said stored temperature data therefrom.
