HYDRORAIN is provided with a SAFETY
TRANSFORMER for the direct connection to a
FLOAT SWITCH used for controlling the water
level into a tank in cooperation with a SOLENOID
VALVE also connected to the device.
In addiction to performing the normal functions
of common pressureflow controls, HYDRO
RAIN checks the water level, the connected
float switch stops the pump and opens
the solenoid valve connected to the device
also, maintaining the water level reserve and
normal function of the pump.
The pump can be stopped before the dry running
control or when the water finish completely,
the solenoid valve can be directly
powered by the device at 230V c.a. or at 24V
c.a. by an external transformer.
