The combination of the measured flow rate and a temperature difference over a device can be
used to determine the amount of energy used by that device. The temperature difference can
either be programmed manually in the converter or be measured with temperature
transmitters, connected to an optional I/O box. in this case, the temperature difference is
determined by measuring the temperature before and after the heat/cold producer/consumer.
4.1 Preparation of energy measurement
1 Install a flow measurement as described in the previous chapter. Make sure that the rail and
converter are installed close to the location of the place where the temperature sensors must
be installed, because of the fixed (limited) length of the sensor cables.
2 Check if temperature transmitters are already available on site.
Transmitters are already available on site:
Make sure that the basis I/O box basis I/O box basis I/O box basis I/O box is used. Connect the temperature transmitters to the 4...20 mA
current input of basic I/O, which is connected to the UFC 300 P.
Transmitters are not available on site:
Make sure that the Extended I/O box Extended I/O box Extended I/O box Extended I/O box is used. In this version, the temperature transmitters are
included. Optionally, clamp-on PT 100 temperature sensors can be delivered, with a
temperature range of 0...120°C / 32...248°F, including two meter cable and suitable for pipes up
to DN300.
