A
very inexprensive device - despite the latest microprocessor electronics.
The FC I is suitable for controlling a measuring point, and especially for
monitoring water treatment plant, which has to be re-generated after a
specified quantity of water has passed though it. When a quantity 10 per
cent less than the value set is reached an indicator starts to flash green;
if the quantity set is reached, the indicator flashed red. The value prior
to re-setting is recorded up to 24 times and can be called up any time. All
values are of course retained even after interrruption of the power supply.
