Abstract
A temperature-sensitive sensor () and a heating temperature-sensitive sensor () are fixed in position in a liquid-tight fashion by welding, with the metal tubular bodies (and) being inserted into the tubular body insertion holes (and) of a vortex detector (). Sealing performance is secured without using any O-ring. The temperature-sensitive sensor () and the heating temperature-sensitive sensor () respectively have lead wires (and) held together with the lead wires () of a vortex detection sensor () within the internal space (), and the lead wires (, and) thus held together are led out toward the flow rate converter (not shown) via a metal pipe (). Since the lead wires (, and) are held together within the internal space () and led out toward the flow rate converter via the metal pipe (), there is involved only one joint portion between the sensors and the flow rate converter. With this structure, explosion-proof performance can be attained easily.
