FLOW SWITCHES FOR LIQUIDS
DOLOMIT
FLOAT SWITCHES
The DOLOMIT float switches find
application in liquid level control in
tanks and wells; they require con-
nection to pumps (or other electrical
equipment). They can be used with
drinking water and sewage as well
as other liquids compatible with the
components of the products.
FLOAT SWITCHES
PRESSURE SWITCHES
FLOW SWITCHES FOR LIQUIDS
Flow switches interrupt an electrical control circuit when the water
circulation fails in the circuit for some abnormal condition (e.g. stop-
ping of motor-driven pumps). They are operated thanks to a blade-
type electrical tripping device (stainless steel blade).
PRESSURE SWITCHES
The PRM pressure switch is with normally closed contacts; when the
pressure of the system exceeds the set pressure, the contacts are
opened thus interrupting the circuit.
The series PA pressure switch automatically controls operation of the
motor-driven pump in accordance with the fixed set pressures.
