First Claim
Patent Images
1. A method for determining the temperature of a liquid flowing in a pipe, without contact with said liquid, said method comprising:
- providing a temperature sensor for sensing said physical value, said temperature sensor having a sensitive part;
providing a connector to insert into said pipe and comprising;
an internal passage extending between two apertures,a flexible membrane adapted to cooperate with a pressure sensor to determine the pressure of said flowing liquid, and also adapted to cooperate with a temperature sensor to determine the temperature of said flowing liquid, said flexible membrane forming a wall of said internal passage; and
fastening said sensor onto said connector;
fastening said temperature sensor to said connector with the sensitive part of said temperature sensor turned towards said membrane;
flowing liquid through said pipe; and
measuring the temperature of said flowing liquid with said temperature sensor.

Abstract
A device for determining a physical value of a liquid flowing in a pipe, without contact with said liquid, said device comprising:
- a sensor (3) for said physical value;
- a connector (2) to insert into said pipe and comprising:
- an internal passage (13) extending between two apertures (11, 12),
- a flexible membrane (6) for a pressure sensor, forming a wall of said internal passage (13); and
- means (27, 62) for fastening said sensor (3) onto said connector (2);
- characterized in that said sensor is a temperature sensor (3) fastened to said connector (2) with the sensitive part of said sensor (3) turned towards said membrane (6).
