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 |

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.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,
If you know that the pipe temperature will exceed 2500F 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.
