1.8 Process gas
NOTE
The process gas must be free of condensate, dust and other contaminants, such
as naphthalene.
Gas connection inlet pressure: 20 - 40 mbar
Gas consumption: 30 - 40 l/h (min. rel. density 0.50 with 0.55 mm
nozzle)
1.9 Linearity and measuring ranges
The measuring ranges cannot be utilized from 0% to 100%. The range is depend-
ent on the gas composition. Ranges of 45-100 % are typical for a measuring range.
Hydrogen content in the gas increases the measuring range span. Inert gases such
as N
2
, O
2
, or CO
2
, reduce the measuring range span.
