2.2.1 Drain vent
The Turb 2000 series has been fitted with a drain vent (Pos.9) in the “OUT” bulkhead fitting. This fitting
allows for atmospheric equalization, thus helping to alleviate bubble formation in the cuvette. Refer to
Figure 4.
Upon initial flow minor leakage may occur through the drain vent. This will subside once normal flow is
established.
For some high pressure systems, where the vent hole continuously leaks, a seal screw is provided
which should be inserted into the vent hole and tightened.
The sensor drain tubing should be routed to a suitable, pressure-free drain. It is not recommended to
reintroduce the drain sample to the process stream.
2.2.2 Wetted materials
WTW accepts no responsibility for damage caused by the introduction of vapors, fluids or other
materials into the instrument process stream which is not compatible with the instrument’s wetted
materials. A list of the wetted materials can be found in the technical data section of this manual.
