Level Transmitters 

Both digital electronic and pneumatic displacement level controllers are used for accurate level measurement or precision level loop control. Fisher® displacement level technology is applied in level, level interface and density applications. Displacement level technology is proven to be reliable and accurate for a wide variety of process mediums and conditions.
