In the past, monitoring the filling level in liquid gas tanks using differential pressure has always been a challenge. This is because the manufacturers of tank equipment had to construct their own measuring systems in order to record the liquid level and the operating …
In the specification of the switch points of a float switch, misunderstandings always lead to unsuitable product designs. How one correctly specifies the switch point of a float switch will be explained here. The basic prerequisite for the correct specification …
Float switches are simple, universally applicable and exceptionally reliable. It is not a coincidence that, today, float switches still represent the most frequently used principle for level monitoring. But how does a float switch actually work? Float switches, in …
A submersible pressure transmitter or level probe is a hydrostatic pressure sensor, specifically developed for the purpose of level measurement. Submersible pressure transmitters, such as the WIKA model LH-20 , are level sensors with special characteristics and …
In a previous blog post, I explained the calculation of the filling height in open geometries and vessels . Unlike open vessels, the calculation of level in closed geometries, such as gas-tight tanks or pressurised vessels, requires a compensation of the pressure of …
