5.2 Flow Rates for Test Air and Reference Air
The systems are factory-set to the correct amounts of test air and/or reference air. The instrument air versions are
designed for an inlet pressure of 1-10 bars. With a higher inlet pressure of 6 bar, it is necessary to readjust the flow of
reference air and/or test air.
The flow rates for air should be in the following range:
Test air: 150l/h - 180l/h
Reference air: 30l/h - 40l/h
5.3 Adjusting Flow Rate (SME 53 with integrated Pneumatics)
In the instrument air version in the Safe Area housing with an integrated pneumatic unit, it is possible to adjust the
reference and test air at the electronic unit.
In this respect, the pump and instrument air versions are different:
 In the pump version ambient air is used. Only the flow rate of test air can be adjusted.
 The instrument air version requires an external supply of clean, dry and oil free air (instrument air) Both
flow rates (test air and reference air) can be adjusted.
In systems with integrated pneumatics unit, the flow rate of reference air can be seen in the menu actual measured
values.
