Other gases on request
Please note:
The consumption sensor corresponds with the current state of technology and basically it can be used
in any flammable and non-flammable gases.
If this consumption sensor is used for measurement of flammable gases (e.g. natural gas and so on)
we expressly would like to point out that the sensor has no DVGW admission, however, it can be used
for measurements in natural gas. A DVGW admission is not mandatory.
The area outside the pipeline (ambient area of the sensor) must not be an explosive area.
