Introduction
Scope of Manual
This instruction manual includes maintenance and parts ordering information for Fisher 249 cageless displacer
sensors.
Although a 249 sensor is usually shipped with attached controller or transmitter, this manual does not include
operation, installation, calibration, maintenance, and parts ordering information for the controller/transmitter or for
the complete unit. For this information, refer to the appropriate controller/ transmitter instruction manual.
Do not install, operate, or maintain a 249 sensor without being fully trained and qualified in valve, actuator, and
accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important
to carefully read, understand, and follow all of the contents of this manual, including all safety cautions and
warnings. If you have any questions about these instructions, contact your
Description
249 sensors are designed to measure liquid level, interface level, or density/specific gravity inside a process vessel.

Page 4: Removing The Displacer And Stem
Instruction Manual 249 Cageless Sensors July 2015 D200100X012 WARNING Always wear protective clothing, gloves, and eyewear when performing any maintenance operations to avoid personal injury. Avoid personal injury or property damage resulting from the sudden release of pressure. Before performing any maintenance procedure: D Relieve any process pressure in the process vessel where the 249 sensor is installed. - Page 5 Instruction Manual 249 Cageless Sensors D200100X012 July 2015 Process residue buildup on the displacer and stem (key 24) may change displacer weight or displacement. A bent stem or a dented or corroded displacer can impair performance. If the displacer rests against the travel stop, appears to be overweight, or causes output drift or other output inaccuracies, it may have been penetrated by process pressure or liquid.
