Level sensors and switches ensure safety by preventing the overfilling of tanks. The certified components from WIKA increase plant safety, e.g. during hydrogen recovery or storage and similar critical applications.
LOHC technology stores hydrogen in an oil to make transport and storage simple and safe. This enables existing fuel infrastructure to be used, e.g. underground tanks at refuelling stations for trucks, ships and planes. On the road to decarbonisation, this could be an important building block because hydrogen could be produced ecologically where green energy is produced and then transported efficiently and safely for use.
With LOHC technology, commercial hydrogen filling stations with over 1,000 kg of stored hydrogen are feasible, on-site, in densely populated areas. Combined with the low cost of supply infrastructure, LOHC technology can significantly reduce the cost of delivered hydrogen.
At the same time, hydrogen is one of the most widely used industrial gases worldwide. However, there is a challenge with decentralised hydrogen supply: Transport is expensive, inefficient and associated with safety risks. Storing the hydrogen in an oil that is difficult to ignite solves all this.
It doesn’t matter whether the hydrogen is delivered to a filling station in the middle of a town or in large quantities to an industrial company. In both cases, the potential danger is very high. Accordingly, safety has top priority here. That is why many operators rely on the certified level sensors from WIKA.
The most important criterion for selecting the right level measuring instrument is therefore the area of application. Is it sufficient to detect only the limit levels of a tank, e.g. dry running or overfilling, or is a level limit switch necessary? However, if the contents of a tank are to be fully monitored, i.e. the current level between 0 % and 100 % is to be measured, level sensors are used. With combined electronics, these can transmit both analogue signals and switching signals.
