Equipment overview and function description

4
The "Flow Control" flow monitor comprises essentially a pipe with a float (3)
and a bypass with adjustable cross section (see Fig. 1). The Flow Control is
adjusted to the lift volume of the pump by varying its cross section with the
control lever - its response sensitivity is adapted accordingly.
The float (3) rises and falls in time with the pump flow pulse in front of the
reed-contact (2). This magnetic float (3) thus opens and closes the reed-
contact (2). It transmits the resulting signals via the flow monitor cable to the
pump.
The pump uses these signals as acknowledgement pulses for its individual
strokes. If there is no acknowledgement pulse when the feed rate drops, the
pump stops after a preset number of error pulses and signals an error (see
"ProMinent
instructions").
In this flow monitor design there is always a flow as the line is not blocked by
the float, just the bypass.
