The four comma separated columns within the data should be formatted in the following order and with
the units indicated:
Column Parameter Units
1 Temperature Deg C or F
2 Sound Velocity (Vs) meters/second
3 Specific Gravity
(relative to water @ 20ºC)
4 Viscosity (kinematic) Centistokes
Once the input data is properly formatted it can then be processed using the PC based UniMass
grid
generating program. Follow the instructions included with this program to generate the final grid data,
which can be directly downloaded to the 1010 flowmeter using HyperTerminal “Send Text File” com-
mand.
NOTE: To properly download and direct the UniMass table to the appropriate flowmeter chan-
nel, follow the instructions outlined below:
1. Establish communication with the flowmeter at 9600 baud or less.
2. Disable all channels (select [Channel Disable] menu cell then [Yes]) if they are actively mea-
suring flow.
3. Select the desired default channel for download of the UniMass table. In HyperTerminal type “cv
0” for Channel 1, “cv 1” for Channel 2, “cv 2” for the virtual channel of a dual beam system or “cv
4” for 4-Beam systems.
4. Select the “Send Text File” command from the HyperTerminal menu and proceed to download
the UniMass grid file.
Enable channel operation then select [Table Active] then [Yes] for the Changing Temp & Vs table.
2.3.3 HOW TO SELECT A PIPE TEMPERATURE RANGE
This menu cell informs the flow computer about the expected temperatures that the transducers will be
subjected to during operation. The default setting, -30
0
F to 225
0
F corresponds with the rated tempera-
ture range of our standard 991 or 1011 series transducers. The other selections provide higher upper
limits of 375
0
F and 450
0
F respectively.
If you know that the pipe temperature will exceed 250
0
F at the transducer mounting lo-
cation, please use this menu cell to select the appropriate range. This will allow the flow computer to
restrict its transducer recommendations to the appropriate environmentally rated types.
