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 Emerson Process Management sales office.

Description

249 sensors are designed to measure liquid level, interface level, or density/specific gravity inside a process vessel.
