Filed: 1984-09-03
Abstract: PURPOSE:To measure exactly a flow rate by eliminating an adhesion of a scale as an insulator from the surface of a reducing mechanism to be inserted into a passage, so that a correct differential pressure to the flow rate is generated. CONSTITUTION:As for a differential pressure generator, generally, an orifice plate 1, a flow nozzle 2, etc. are given, but with respect to each of them, an adhesion of a scale is observed in case of a feed water flow meter, etc. of a boiler. This cause is due to an electrical interaction of the potential of the surface of a metal of the differential pressure generator contacting to a fluid, and an ionized scale component in the fluid. In order to eliminate this action, the differential pressure generator itself is constituted of insulating ceramics, or there is a method for adopting a system for covering the surface with an insulator by using a metallic material such as stainless steel, etc. as a base material, but it is practical that a metallic base material manufactured with a high accuracy is covered with ceramics of about several micra - scores of micra thick by means of vapor-deposition or ion plating, etc. In this way, a thermal expansion is determined by a quality of the metallic base material, and the measurement can be executed with a high accuracy.
