Overview
Flow sensor
A flow sensor is a device that measures the flow volume of water, pure water, compressed air, gas, drugs, steam, and similar liquids or gases. Flow sensors come in various types that each employ different detection principles. Examples of these include turbine sensors, in which the target fluid flows through a turbine and the number of revolutions is converted into a flow value; rotameters, in which flow is detected by the movement of a float installed in a conical pipe; and electromagnetic sensors, which apply Faraday's law.
