The flowmeter measures the mass flow rate and stream temperature of the process media. The display
can be set to present the flow rate and temperature in a variety of units. The factory will set the units
of measure to those specified at order entry time. There are other units of measure that can be chosen.
Two units that will appear are m and mm. The letter m stands for 1000 and mm stands for 1,000,000.
Menu level 3.1 provides the options for changing the output units of measure. The units of measure
can be selected for temperature at menu level 3.2. The units of measure for the totalizer are available
at menu level 3.3.
To choose a new unit of measure for flow rate:
1.
From the Main menu press 3. The 3.0 DISPLAY SETUP menu title will appear.
2. Press 1, the Flow Setup option.
3. At this point there are three choices, Mass, Std Volume and Std Velocity. Table 7 summarizes
the choices contained in Mass, Std Volume and Std Velocity.
4. By pressing 1, 2, or 3, the display will prompt the user to enter the user password (if it is
enabled) and then the respective mass, volume or length units from Table 7. Enter the desired
measurement type. For example, pressing 1 will show the following display:
1=LB, 2=KG or 3=TNS.
5. Enter the desired time units, seconds, minutes, hours or days.
6. If Mass or Std Volumetric units have been selected, enter the pipe cross-sectional area. There
is the option of entering the area directly or, for circular pipes, entering the inside diameter.
7. Enter the desired area units.
8. Enter the pipe area or the pipe inside diameter. Press any key twice.
9. When prompted to Save permanently enter Y for yes.
NOTE: The term Std refers to standard or standard conditions. Standard volume refers to the
space a gas occupies at a defined pressure and temperature. The factory uses 14.7 psia
and 70°F as its standard conditions. Std Velocity is defined as the standard volumetric
flow rate divided by the pipe cross-sectional area.
Table 7. Flow Rate Units of Measure
To choose a new unit of measure for temperature:
1.
From the Main menu press 3. The 3.0 DISPLAY SETUP menu title will appear.
2. Press 2, the Temperature Setup option.
3. Press 1 to change the units for temperature.
4. After entering the user password (if it is enabled) there will be 4 choices: (°F) degrees
Fahrenheit, (°C) degrees Celsius, (K) Kelvin and (R) Rankine. Press the appropriate
number corresponding to the desired temperature units.
5. When prompted to Save permanently enter Y for yes.
