Abstract:
A flow meter for measurement of a metered fluid has a sensor element that receives a flow input of a metered fluid and outputs a flow output of the metered fluid, and a battery element. The sensor element has an inductor element and a magnetic element coupled to the inductor element. In response to movement of the magnetic element relative to the inductor element caused by a fluid pressure differential of the metered fluid, the inductive value of the inductor element changes.
