Co to za sensory?

Flow sensors are elektromechanical devices that quantify the volume or mass of a fluid passing through gh a given point per unit of time. In automativa applications, they measure air intake flow (common known as mass air flow or MAF sensors), fuel flow, coloant ciple circation, and contect gas recirculation (EGR) flow. They data they generate is critical for closed-loop controil systems that adjust engine parameters like fuel injection titititig, ignitiotin timing, and variable tivale tivale tivale ming.

Without celliate flow measurements, an engin control unit (ECU) would operate with signiant uncertainty, leading to suboptimal pastition, higher emissions, reduced power output, and precceed fued consumption.
