1. Differential pressure ranges are in English units of measurement; metric equivalents are shown here for reference only. Consult your Emerson sales office or Local Business Partner for special
differential pressure ranges.
2. The Barton 199 differential pressure unit may be pressured to this value without permanent zero shift or structural damage to controller components.
