The RESOL WMZ is a universal calo-
rimeter for thermal solar systems and
conventional heating systems. This ca-
lorimeter especially takes into consi-
deration that the density and the spe-
cific heat capacity of the heat transfer
fluid depend on the temperature as
well as on the mixing ratio of water/
glycol. The calorimeter RESOL WMZ
calculates the heat amount using the-
se parameters, the measurement of
feed flow and return temperature by
2 precision-temperature sensors and
the evaluation of the impulses of the
flowmeter. A power failure protection
guarantees that the adjusted system
parameters and the calculated heat
quantity are maintained in the case of
power loss. By means of push buttons,
different channels can be chosen and
Power supply: 115 V~
Power consumption: ca. 2 VA
Ajustment values:
• Volume concentration of
glycol:
0 ... 70 % (1%-steps)
• Pulse rate volumetric flow
rate:
0 ... 99 l/Imp (1 l/Imp - steps) for
flowmeter RESOL V40
user levels can be changed. In the first
level, the temperature at the selected
measuring points, the heat gained, the
actual power or the volumetric flow
rate of the system are indicated on
the graphic display. A control lamp is
also installed for indication of sensor
defects and false sensors connections.
A second level is used for displaying
system adjustment values and control
values, which can be analoguely ad-
apted to changes in the systems. The
power supply is effected via a mains
plug. Additional RESOL modules can
be connected to a bus connection.
The VBus connection enables the
®
transmission of display values to a
corresponding RESOL controller, PC
or datalogger in order to be further
processed or evaluated.
