3.1 Functional description
The "OV-DMC 3" measuring system is specially
designed for the simple and rapid adjustment
of heating and cooling systems.
Communication takes place via Wi-Fi using
standard commercial smartphones, tablets,
notebooks, and PCs.
The "OV-DMC 3" also enables permanent re-
cording of the differential pressure and the flow
rate. This means that system conditions can be
recorded over longer periods of time.
The supply flow and return flow temperatures
can be simultaneously measured using an ex-
ternally connected PT1000 temperature sensor.
