1.4 Functional Characteristics

SMV800 SmartLine Multivariable Transmitters measure 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 may be read by a connected Host.
Available communication protocols are Honeywell Digitally Enhanced (DE) and HART, Modbus
RTU. Digital or Analog (4-20ma) output modes are available. SMV800 measures Process
Temperature from an external RTD or Thermocouple.
Universal temperature input is available as a selectable feature with the device or as license enabled,
field upgradable option.
With Modbus protocol, Flow calculation capability also is available as selectable feature with the
device or as license enabled, field upgradable option while this is a standard feature with HART and
DE protocols.
SMV800 supports 6 device variables:
1. Differential Pressure
2. Static Pressure
3. Process Temperature
4. Calculated Flow Rate
5. Totalizer (HART and Modbus only)
6. Meter Body Temperature
For DE transmitters, Differential Pressure, Static Pressure, Process Temperature or Flow may be
assigned to the analog output. In HART transmitters, Differential Pressure, Static Pressure, Process
Temperature, Flow and Totalizer may be mapped to device variables PV (analog output), SV, TV or
QV and Meter Body temperature may be mapped to SV, TV or QV. All six variables are Modbus
process variables.
SMV800 supports Dynamic Compensation Mode for Industrial Flow Standards according to ASME-
MFC-3-2004, ISO5167-2003, Gost 8.586-2005, AGA3-2003 and flow calculations for Averaging
Pitot Tube, Integral Orifice, VCone, and Wedge and Fixed Parameters. When Compensation Mode is
Standard and Fluid Type is Liquid, the device calculates density coefficients for user-selected High
and Low Temperature ranges.
SMV800 supports the following primary elements:
