A Review of Your Flow Sensing Options

Flow sensors are used to measure both gas and liquid flows in many monitoring and control applications. Flow can be variously defined (e.g., mass, volume, laminar, turbulent). The amount of a substance flowing (mass flow) is usually the one of interest, and if the fluid's density is constant, a volume flow measurement is generally the easiest to perform. Some technologies work for both gas and liquid flow; others are specific to what they are measuring.
