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 switch: What is it and how does it actually work?
| Enrico BossartFloat 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 …
The design of a submersible pressure transmitter / level probe – Part 1
| Enrico BossartA 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 …
Hydrostatic level measurement in closed geometries – calculation of the filling height
| Enrico BossartIn 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 …
Hydrostatic level measurement in open geometries and vessels – calculation of the filling height
| Enrico BossartIn my last blog post, I introduced the way in which hydrostatic level measurement works . The hydrostatic pressure is used to determine the level through the measurement of the liquid column and is directly proportional to the filling height, as well as to the density …
