3.1.2 Automatically adjustable Systems
Because of the inconveniences with the “wet” adjustment and checking of such
systems, Bürkert developed microprocessor controlled systems, which can be
adjusted without gasoline flow.
The control of the vapor flow is accomplished either through a proportional valve
(e.g. Bürkert type 2832, Figure 4) or through a speed controlled pump (Figure 5).
