Flow switch type IV

The Flow Switch is designed to give an initial alarm at a very low flow and
still capable of allowing a high full liquid flow passing through when pumps
or valves are activated by the micro switch. This is since the Flow Switch is de-
signed with a variable flow passage area which increases as the liquid flow
rate increases. It is also equipped with an internal rubber diaphragm to make
the switch even more sensitive atlow liquid flows.
