Reduction of methane emissions in the gas distribution network through the use of a mobile gas flare

Reduction of methane emissions in the gas distribution network through the use of a mobile gas flare

Climate protection and climate neutrality are probably the greatest challenges of our time. Since the beginning of industrialisation, global warming, caused by the greenhouse effect, has affected people and the environment in many different ways. The main causes of this are emissions of greenhouse...

Gas readings – Differences between diffusion and pump measuring devices

Gas readings – Differences between diffusion and pump measuring devices

There are different types of devices for detecting gas leaks. We distinguish here between pump and diffusion devices. For everyday work, it is important to know the difference, as the gas indications of the respective device type must be evaluated differently. In which cases does it make sense to...

Effects of the addition of hydrogen to natural gas on the explosion protection of gas measuring and gas warning devices

Effects of the addition of hydrogen to natural gas on the explosion protection of gas measuring and gas warning devices

In our article of 09 June 2020 on the use of existing measurement technology in gas networks with hydrogen components, we dealt with the properties of hydrogen, the suitability of different sensor technology and the explosion protection of the devices when used in natural gas-hydrogen mixtures. In...
