The AF 100 Series air flow monitors are designed specifically for measuring air flow/velocity in high particulate processes and stacks. There are no orifices or thermal elements to clog and installation is simple with no precise alignment or calibration. Abrasion-proof probes are available for small pipes to large ducts while non-intrusive ring sensors are available for tubing. Combining a time-of-flight/cross correlation principle with the company’s field-proven charge induction and ultra low current measurement techniques, these monitors provide absolute air velocity/volume measurement without concern for contamination from particulate. Applications include process pipes, injection lines, dryers, cyclones, precipitators, baghouses and stacks.
