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 DT 500 corresponds with the latest state of technology and can
generally be used for burnable and non-burnable gases.
For the use in e.g. natural gas, the sensor will be calibrated in natural gas. The calibration protocol
(inspection certificate) is included in the scope of delivery.
The area outside the pipe (environment of the sensor) is not allowed to be an explosive area (Ex-area)
