freely accessible, container or body of water as well as in a sealed tank with positive or negative pressure. Hydrostatic pressure can be measured in either an open, i.e. Dynamic pressure due to flow is not recorded. Neither the type of medium nor whether or not the fluid is in motion plays a role here. The fluid at rest exerts a dead weight on the layers below as a result of its own mass. Hydrostatic pressure is the pressure that forms within a liquid or gas at rest due to the influence of the force of gravity. The most common form of electronic fill level measurement is hydrostatic pressure measurement. Using an additional radio module, a purchase order can be triggered automatically in various applications as soon as the fill level falls below a certain threshold. Determining the exact fill level right down to centimetre can therefore save the customer a fair bit. Climate change, forest fires, glacier melting and the resulting rise in world sea levels are all arguments in favour of the proper, well-thought-through management of groundwater resources.įurthermore, monitoring the fill level in tanks or sealed containers of oil or similar liquids is very important, especially on cost grounds, and can also double as theft protection. No longer confined to the Global South, general water scarcity is now an ever-present issue in technologically developed countries as well.
