专利汇可以提供Apparatus for indicating the rate of fluid flow专利检索,专利查询,专利分析的服务。并且Apparatus for indicating fluid flow rate which includes a thermistor carried by a mesh and arranged for connection in an electrical circuit including an indicating instrument, the time dependent pattern of variations in the rate of flow of fluid through the mesh being indicated by the indicating instrument because the resistance of the thermistor varies with the fluid flow rate. The thermistor can be calibrated by a comparison of its output signals with the pressure differential across the mesh for one fluid flow rate. The element may be connected into the electrical circuit by leads having the properties of a hot wire anemometer element, the leads being disposed on opposite sides of the mesh and arranged to indicate the direction of fluid flow through the mesh. A peak flow meter having mechanical means for measuring the peak rate of flow of air blown by a human subject, has a thermistor carried by its gauze mesh filter and arranged to give an indication of the time dependent pattern of variations in the rate of flow of air blown by the subject.,下面是Apparatus for indicating the rate of fluid flow专利的具体信息内容。
