Article No. 417101795
The compact metering device is a metering system for stone and corrosion-protective
chemicals in drinking water pipes. It works hydraulically / electrically and is suitable for the
use of metering media similar to water.
As the water flows through, a precision impeller water meter measures the flow of water
and emits a pulse for each volume unit to the control electronics of the metering pump,
whereupon it performs a metering stroke.
The metering device has been tested and certified by the DVGW (German
Technical and Scientific Association for Gas and Water) using the chemical
ST-DOS T-300 from Schweitzer Chemie.
When these chemicals are used, a concentration of 100 ppm is specified.
Therefore, the metering capacity of the compact metering device is preset
to a concentration of
100 ml/m³ at a back-pressure of 0.6 MPa (6 bar).
Other concentrations can also be set when using other chemicals
Ä Chapter 7.2 'Set the metering capacity of the pump (mechanical)'
on page 35 by adjusting the metering capacity.
The current setting can be secured by sealing the cover of the device with
lead.
NOTICE!
Please note that if you use other chemicals, this will invalidate the DVGW
approval.
CAUTION!
It is essential to ensure that the water flowing through the water meter is
clean, has a neutral pH and is no hotter than 30 °C.
Properties and safety when working with the metering agent used with this
pump can be found in the safety data sheet on the metering agent
container.
It is advisable to use a suction pipe with an empty signal device in order to
protect the metering system! The empty signal system causes the pump to
cut off if the medium (in the container) drops below a certain level.
