9.3Inspecting and Cleaning Barrier Diaphragms

Background

Procedure

Depending on the characteristics of the process medium being measured, sediment or other foreign particles may collect in the process head cavity/chamber and cause faulty measurement. In addition, the barrier diaphragms in the transmitter’s meter body may become coated with a residue from the process medium.

In most cases, you can readily remove the process heads from the transmitter’s meter body to clean the process head cavity and inspect the barrier diaphragms.

The procedure in Table 27 outlines the general steps for inspecting and cleaning barrier diaphragms.

Action

Close all valves and isolate transmitter from process. Open vent in process head to drain fluid from transmitter’s meter body, if required.

ATTENTION We recommend that you remove the transmitter from service and move it to a clean area before taking it apart.

Remove nuts from bolts that hold process heads to meter body. Remove process heads and bolts.
