Abstract

PURPOSE: To detect the stress generated within a barrier wall with a detecting means and lower production cost with a simple construction by providing a stress detecting means so as to become integral structure in the barrier wall disposed in a pipeline in which the measuring fluid flows, in such a manner that it does not flex and deform.
CONSTITUTION: An orifice 2 constituting a barrier wall to flow is fixed via flange 21 to a pipeline 1 in which the measuring fluid flows. The thichness d in the flow direction of the fluid of the orifice 2 is made thickner than that of known ones so that the entire part will not flex and deform. A stress detecting part 3 is so provided as to become integral structure with the orifice 2 in the orifice 2. To this end, a recess 31 is formed from the flange 21 in the orifice 2 and two piezoelectric elements 4 constituted through common use of one piezoelectric material 40 are disposed therein in such a manner that the center thereof parallels to the plane opposing to the flow of the orifice 2. The elements are then secured by casting sealing material 32 being insulating material such as glass material or the like into the reces. The pressure of the liquid being applied to the orifice 2 is then detected.
