Application
The Thermometer can be used for measurement of the gas temperature while measuring the gas flow. Among other reasons, this is necessary if the measured and indicated actual volume of gas must be recalculated into the norm volume. The actual volume is the volume at the actual temperature and the actual pressure. The norm volume of a gas is the volume at norm conditions which are (in Germany).
The norm volume of a gas is the volume at norm conditions which are (in Germany):
| Norm Temperatur | = 273,15 Kelvin ( = 0 °C) |
| Norm Druck | = 1.013,25 mbar |
The formula for converting the actual volume into norm volume is:

Installation
Unpack the Thermometer which is mounted into a T-piece. According to the rules for calibration and measurement with gas meters, the thermometer must be positioned at the gas outlet of the meter (see right picture above). The gas outlet nozzle is labelled accordingly.
Mount the Thermometer onto the gas outlet nozzle by tightly screwing the union nut which is attached to the Thermometer. Thus, the Thermometer is ready for use
