PURPOSE:To achieve the balance of temperature at both end parts through thermal connection of both end parts of a pipe by providing a surrounding body made of a goove conductor of heat and further to uniformalize the distribution of temperature in the inside space of the surrounding body by giving the function of thermal reflection to the inside thereof. CONSTITUTION:The pipe 1 passing fluid to be measured through is wound by coils 2 and 3 formed of heat-sensitive resisting wires and is fitted with the surrounding body 9 made of a goove conductor of heat with the 1st space 11 provided appropriately between the two coils. The surrounding body 9 is connected thermally with the pipe 1 at the parts of the flow-in side (b) and flow-out side (c) thereof. The surrounding body 9 is given the function of thermal reflection on the inside surface 9a thereof and further an outside enclosing body 10 provided with the 2nd space 12 is fitted to the pipe 1. The thermal convection inside the spaces 11 and 12 is prevented by evacuating them. By this constitution, the distribution of temperature inside the space 11 including the pipe 1 is uniformalized. |
