Scanner network
Three additional integral uncompensated pulse/frequency inputs
Bidirectional flow measurement
Up to 8 gas streams using gas chromatograph inputs or user-entered static compositions
16-point calibrations for all inputs (linear factory and multipoint meter factor calibrations also
supported); see
Table 1.6—Flow Correction Factors, page 18 for information on multipoint
meter factor calibration
Stacked differential pressure and static pressure inputs for rangeability
RTD Inputs 2 channels
100-Ω platinum RTD with 2-wire, 3-wire, or 4-wire interface
