INSTRUCTIONS Volumetric IR Process Gas Monitor PIRVOL Series APPLICATION PIRVOL Infrared Process Gas Monitors provide continuous measurement of hydrocarbon vapors in the range of 0 to 90% by volume. The PIRVOL-LT model provides an analog 4 to 20 milliampere signal output that is proportional to methane vapor concentrations from 0 to 90% by volume, while the PIRVOL-VR model provides an analog 4 to 20 milliampere signal that is... - Page 4 PIRVOL-LT CROSS SENSITIVITy— Table 1—Current Loop Output Levels and Corresponding Status Indications PIRVOL-LT provides a linear analog 4 to 20 mA signal output in response to methane vapor concentration Current Level Status of 0 to 90% by volume. The presence of other 23.0 ma 100% by volume hydrocarbon vapors in the sample stream will cause...
