the material being a liquid (contained in a hollow body having parts which are deformable or displaceable under the pressure developed by the material G01K5/32)

Full Title

Measuring temperature based on the expansion or contraction of a material (G01K9/00 takes precedence; giving other than momentary value of temperature G01K3/00) > the material being a liquid (contained in a hollow body having parts which are deformable or displaceable under the pressure developed by the material G01K5/32)
