9.1 Introduction
This section covers basic transmitter and sensor troubleshooting. Problems in the magnetic
flowmeter system are usually indicated by incorrect output readings from the system, error
messages, or failed tests. Consider all sources when identifying a problem in the system. If the
problem persists, consult the local Rosemount representative to determine if the material
should be returned to the factory. Emerson Process Management offers several diagnostics that
aid in the troubleshooting process. Instructions and procedures in this section may require
special precautions to ensure the safety of the personnel performing the operations. Read the
following safety messages before performing any operation described in this section. Refer to
these warnings when appropriate throughout this section.
The Rosemount 8732EM performs self-diagnostics on the entire magnetic flowmeter system:
the transmitter, the sensor, and the interconnecting wiring. By sequentially troubleshooting
each individual piece of the magmeter system, it becomes easier to identify the problem and
make the appropriate adjustments.
If there are problems with a new magmeter installation, see 9.3 Installation check and guide
below for a quick guide to solve the most common installation problems. For existing magmeter
installations, Table on page 161 lists the most common magmeter problems and corrective
actions.
