CAUTION
Danger of burns when touching surfaces!
During operation, the components, shaft and connection
nut, can reach a temperature close to the process temperature.
To avoid burns, protection against contact must be ensured at
elevated process temperatures, as there is a risk of medium to
light injuri.
Burnable gases
If this consumption sensor is used for measurement of burnable gases (e.g. natural gas) we
explicitly point out that the sensor has no DVGW (= German Technical Association for Gas and
Water) admission, however, it can be used for natural gas.
A DVGW admission is not mandatory.
The consumption sensor VA 500 corresponds with the latest state of technology and can
generally be used for burnable and non-burnable gases.
The area outside the pipe (environment of the sensor) is not allowed to be an explosive area (Ex-
area)
