Title: Liquid sensor device
Inventor: MURAI TERUMIZU
IPC: G01P13/00
Filed: 1987-05-22
Abstract: PURPOSE:To easily detect whether or not there is a flow by adding a piezoelectric element which detects variation of an acoustic wave or pressure due to the disturbance of fluid on the wall of the flow passage for the fluid. CONSTITUTION:When the fluid moves in the flow passage such as a pipe, it is disturbed by the internal wall or connection part of the flow passage, so an ideal laminar flow is not obtained and a turbulent flow which is extremely irregular spatially with time is generated. Such a turbulent flow generates elastic waves of various frequencies according to the environmental condition of the generation. Therefore, the piezoelectric element 1 is fixed on the external surface of the tube 3 wherein the fluid flows with an adhesive 1, and then an acoustic wave or ultrasonic wave which is generated by the fluid in the tube is detected from variation in the piezoelectric potential of the piezoelectric element 1, thereby detecting whether or not the fluid flows.
