Section 8: Selecting and Configuring Operation Modes In this mode, the user has the option of entering the density of material or the full tank pressure. Also, the user must enter tank height and tank volume. Finally, the user must select level units, which can be in units of height, volume, or mass. The entered information is used to make level calculations in the units selected by the user. For non-uniform tanks, the user must also fill out the 22-point curve table indicating the relationship between height and volume. 8.4: Level To set the Field Unit to this operation mode, you must go to the configuration menu of the Field Unit via the Software. For further instructions on getting to the configuration menu see Section 9.2 of the Wireless Instrumentation Manager User Manual. Once you have opened the configuration menu, select the Operation Mode tab at the top of the menu and select Fluid Level from the mode menu. You should then see a menu like the one shown in Figure 8.4.
