Bewados ® module mineral substance metering units
are used for metering BWT Quantophos mineral ag-
gregate combinations.
Function Function
Function Function Function
The water metre in the mineral substance metering
unit measures the water volume flowing through and
sends pulses to the electronic controller. The con-
troller controls the drive motor for the piston meter-
ing pump, which proportionally adds the active sub-
stance to the water flow using the injection point
(4 4 4 4 4 ). The metering frequency appears on the display
(6 6 6 6 6 ).
A built-in level monitor switches the unit off auto-
matically once the active metered substance has
been used up to prevent the metering pump from
running dry. An audio signal is also emitted.

The self-monitoring electronic controller reliably
prevents improper overdosage if a fault occurs and
switches off the unit. The fault appears on the dis-
play (6 6 6 6 6 ) and is indicated by an audio signal.
Bewados mineral substance metering units are
DVGW, ÖVGW and SVGW tested in the original
ex-works settings with Quantophos F mineral sub-
stance combinations.

placed (indicator flashes without

If hot-water units are installed downstream, a non-
return valve should be installed. Metering units
have an integrated non-return valve and must not
be installed between the hot water heaters and
excess pressure valve.
A protective filter must be installed upstream from
the mineral substance metering unit to protect the
unit from foreign particles.
The installation site must be protected against frost
and must guarantee the protection of the unit from
all types of chemicals, paint, heating oil, lees, sol-
vent vapours, heat sources above 40°C and di-
rect sunlight.
The electrical outlet must be no more than 1.2m
from the mineral substance metering unit.
