Optical Scientific’s OFS200 Air-Flow Sensor
Optical Scientific's (OSi) patented optical flow sensor (OFS) makes drift-free measurements across the entire stack, duct or pipe diameter and calculates an accurate average flow reading. It is the only flow sensor that gives a true non-contacting cross-stack flow measurement of the process.
The OFS uses our EPA method 14 approved optical scintillation technology. The optical scintillation technique relies on advanced digital signal processing (DSP) electronics to 'see' and measure the movement of turbulence found in a gaseous flow stream to provide highly accurate, path-averaged air velocity measurements. The accuracy of the OFS has been proven both in NIST's wind tunnel and in numerous real-world installations.
