16 Heat Flow Measurement

144

UMFLUXUS_F7V4-6-2EN, 2017-10-01

In the BTU mode, additional units of measurement are available for the physical quantity and the heat quantity (see sec-
tion 11.2). The unit of measurement displayed during the measurement will be adjusted automatically:

16.3.5

Automatic Toggling of the Display in the Lower Line

In the BTU mode, it is possible to activate automatic toggling of the display in the lower line. Press key

three times

during the measurement. The following physical quantities will be displayed at an interval of 3 s:
• physical quantity selected in the program branch

Output Options

• medium temperature in the supply line
• medium temperature in the return line
• difference between the medium temperatures in the supply line and the return line
Press key

three times to deactivate the automatic toggling.

16.4

Measurement

Start the measurement as usual.

For the activation of the heat quantity totalizer see section 11.2.

If no heat flow coefficients are available for the selected medium, an error message will be
displayed. For the input of the heat flow coefficients, see section 13.3.4.

The two temperature inputs are checked and the measured temperatures are displayed.
Press ENTER.

If a temperature cannot be measured (the temperature probe is not connected or is defec-
tive), the error message

?UNDEF

will be displayed.

If

Fixed input val.

has been selected during the configuration of the temperature in-

put, the temperature input (

Ts

) or the return temperature (

Tr

) has to be entered now.

For simulations, it is possible to enter both the supply and return temperatures as con-
stants. In this case, do not connect the temperature probes to the transmitter.
Enter the medium temperature. Press ENTER.

The measured heat flow (in the BTU mode

) is displayed.
