! Note!
• The engineering units of all the measured variables shown here can be set in the “SYSTEM UNITS” group.
• If the fluid in the pipe flows backwards, a negative sign prefixes the flow reading on the display.
MASS FLOW
MODBUS register:
Data type:
Access:
0000
2007
247
Float
read
The currently measured mass flow appears on the display.
Display: 5-digit floating-point number, including unit and sign
(e.g. 462.87 kg/h; -731.63 lb/min; etc.)
VOLUME FLOW
MODBUS register:
Data type:
Access:
0001
2009
253
Float
read
The calculated volume flow appears on the display. The volume flow is derived
from the measured mass flow and the measured density of the fluid.
Display: 5-digit floating-point number, including unit and sign
(e.g. 5.5445 dm
3
/min; 1.4359 m
3
/h; -731.63 gal/d; etc.)
CORRECTED
VOLUME FLOW
MODBUS register:
Data type:
Access:
0004
2011
Float
read
The calculated corrected volume flow appears on the display. The calculated
corrected volume flow is derived from the measured mass flow and the reference
density of the fluid (density at reference temperature, measured or fixed entry).
Display: 5-digit floating-point number, including unit and sign
(e.g. 1.3549 Nm
3
/h; 7.9846 scm/day; etc.)
DENSITY
MODBUS register:
Data type:
Access:
0005
2013
249
Float
read
The currently measured density or its specific gravity appears on the display.
Display: 5-digit floating point number, incl. unit,
corresponding to 0.1000 to 6.0000 kg/dm
3
(e.g. 1.2345 kg/dm
3
; 993.5 kg/m
3
; 1.0015 SG_20 °C; etc.)
REFERENCE
DENSITY
MODBUS register:
Data type:
Access:
0006
2015
Float
read
The density of the fluid, at reference temperature, appears on the display. The
reference density can be measured or also specified via the function FIXED
REFERENCE DENSITY (6461), (see Page 113).
Display: 5-digit floating point number, incl. unit,
corresponding to 0.1000 to 6.0000 kg/dm
3
(e.g. 1.2345 kg/dm
3
; 993.5 kg/m
3
; 1.0015 SG_20 °C; etc.)
TEMPERATURE
MODBUS register:
Data type:
Access:
0008
2017
251
Float
read
The currently measured temperature appears on the display.
Display: max. 4-digit fixed-point number, including unit and sign
(e.g. -23.4 °C; 160.0 °F; 295.4 K; etc.)
PRESSURE
MODBUS register:
Data type:
Access:
0009
2089
257
Float
read
The specified pressure appears on the display.
Display: max. 4-digit fixed-point number, including unit and sign
(e.g. 50 barg, etc.)
