Dwyer Series CAM Compressed Air Meter

The Series CAM Compressed Air Meter operates by the calorimetric measuring principle to detect the standard volume flow of operating compressed air. It is designed specifically to evaluate the current flow rate and the current consumed quantity in compressed air systems. With an easily programmable digital display, this unit offers a quick, accurate readout. The Series CAM is constructed of high-grade materials and is virtually maintenance free.
