SIL 2 and SIL 2 does not automatically equal SIL 2
When using pressure sensors in safety-relevant applications, sooner or later one must ask the question whether the SIL evaluation of the proposed pressure sensor is sufficient for the application. Often, the user tends to favour pressure sensors with higher SIL classifications because these supposedly offer higher safety than sensors with a lower classification.Unfortunately, in the […]

Effects of temperature-related density changes on hydrostatic level measurement
With hydrostatic level measurement, temperature fluctuations in the medium have an effect on the accuracy of the measurement result. But why is that, and how can you minimise the influence of temperature on hydrostatic level measurement?In the blog post “Hydrostatic level measurement in open geometries and vessels” the calculation of the filling height is explained […]
Level measurement in ground water
The recovery of drinking water from ground water has top priority in many countries. In Germany, this method has a share of about 70 per cent in the water supply. The water drawn from depths of several hundred of meters below the earth’s surface is normally in perfect hygienic condition.The ground water is pumped up […]
