Abstract
Techniques that enable the installation of a level sensor capable of continuously detecting a level of fluid in a vessel or tank and capable of being integrated in a larger control system. Advantageously, the sensor head of the level sensor can be installed on existing installations with an existing displacer or float and an existing member or rod. The techniques thus enable process plants to easily and affordably replace pneumatic level sensors with a more environmentally friendly option.
