LexcomSys™ GFM-3XXXUC Programmable Gas / Air Flow Meter and Flowswitch Controller
The LexcomSys™ GFM-3XXXUC is a versatile, highly configurable, high performance USB flow meter specifically designed to suit a wide range of applications in mind including testing, production, research, medical, and scientific. Its unparalleled performance, with a particular reference to very high sampling rates supported with excellent sensitivity, makes it an excellent choice for applications concerning reconstruction of high frequency flow change characteristics in gas propagation.
Examples include air pump / fan performance analysis, failure prediction, flow path optimisation, turbulence reduction, and other, more conventional flow measurement applications where high sampling rates can lead to a massive increase in effective accuracy of readings over a set period.
