SmartLine Multivariable Transmitter in a process system. The following areas are covered:
•

Safety

•
Input and output data
•
Reliability
•
Environmental limits
•
Installation considerations
•
Operation and maintenance
•
Repair and replacement
2.2 Safety

2.2.1 Accuracy

The SMV800 SmartLine Multivariable Transmitter measures Differential Pressure, Static
Pressure (Absolute or Gauge), and Process Temperature. These measurements are used to
calculate Volumetric or Mass Flow rates. The measured values and calculated flow values
may be read by a connected Host.

2.2.2 Diagnostic Messages

Transmitter standard diagnostics are reported in the two basic categories listed in
Table 5. For devices configured for Analog Output, problems detected as critical diagnostics
drive the analog output to the programmed burnout level for HART and DE. Problems
detected as non-critical diagnostics may affect performance without driving the analog output
to the programmed burnout level. Informational messages (not listed in
report various Transmitter status or setting conditions.
The messages listed in Table 4 and the messages listed in Table 5 are specific to the SMV800
Transmitter with HART or DE Option. HART and DE diagnostic messages are listed and
described in the SMV800 SmartLine Multivariable Transmitter HART/DE Option Manual,
document number 34-SM-25-06. Table 6 and Table 7 are specific to the SMV800 Modbus
Transmitter. Diagnostics information related to Modbus transmitter are available in the
SMV800 SmartLine Multivariable Transmitter Modbus Communication Manual, Document
# 34-SM-25-09.
