Level Devil will come up displaying its main screen, which is a tabular list of all sites (customers) and tanks.  Current tank levels are shown in inches or gallons or any of several units of measure options.  The column order can be rearranged and customized to suit the user's needs.  You can use the scroll bar to see the other columns that are available.  The column selection and arrangement can be changed by clicking "View", then "Select Columns".

Click the drop-down arrow in the "Sort Order" box (the default is "Group, Site, Tank").  Select and click "Low Alarm".   This changes the sort criteria to display only those sites and tanks that are in the "low" VMI status zone.  This status means it is time to schedule a routine re-supply shipment to the tank.  If a shipment has already been scheduled (but has not yet arrived), the "Ack" (Order Acknowledgement) column will show an "ACK" indicator.  When the shipment arrives and the tank is filled back into the "OK" zone or above, the "ACK" indicator will disappear automatically and the tank will no longer show up in a "Low Alarm" sort.

Sort next on "Critical (Filling Process)".   This sorts for any tanks that have entered the critical low status zone.  In an ideal world, no tank should ever be critical -- a re supply shipment would normally be scheduled to arrive before the tank reaches this level.  A system user would treat this condition as a red flag indicating that something could be wrong -- a shipping delay, transportation problem, missed delivery, etc.   Urgent follow-up work is needed.

With a critical tank, the first thing the system user would do is click on the "Critical" indicator in the alarm column.  This brings up a window with the details about when the re-supply  shipment was scheduled, who scheduled it, the shipment size and other information the system user will need to quickly find out what caused this problem and what needs to be done  to correct it.

On the main screen, select "Group, Site, Tank" from the "Sort Order".   Pick one site/tank line and double click anywhere except in the alarm column.  This will bring up a pictorial representation of the tank showing its current level, with color-coded level settings that are customized to that particular tank.  The 5 color-codes-Red, Orange, Yellow, Light Green, and Dark Green, make it easy to see what the current condition of the tank is. The 2 basic settings for the color-codes are Filling, and Emptying. "Filling" is for a tank that is normally full. "Emptying" is for a tank that is normally empty.

When set to "Filling", a full red tank indicates the tank is filled very near to the maximum storage capacity. A dark green indicates it is filled above it's normal maximum fill level. A light green indicates the tank is "OK" in it's normal operating range. A yellow tank level indicates the tank is low. An orange tank level means the level is "Critical" low, and a low red tank indicates an inaccessible level.

When set to "Emptying" a full red tank indicates the tank is filled very near to the maximum storage capacity. An orange tank indicates it is filled to "Critical" full level. A yellow tank level indicates it is filled to the normal "Full" level. A light green indicates the tank is "OK"  in it's normal operating range or empty. A low dark green tank indicates an inaccessible level.

To get a quick view of the tank cycle time for estimating the time to need, click the "plot" button to bring up graphic historical data for this tank.  Tabular historical data is available with the "tabular" button.  Either type of historical data can be printed. Exit to the main screen.

Click on "Accounts" then "Tank Setup" at the top left. When the setup window appears, click the "Geometry" button.  This is where tank dimensions are entered so that the system can convert the tank level reading from inches to gallons.   Click the dropdown arrow in the upper left part of the geometry window.  Select and click a tank shape, and a line drawing will appear with spaces for you to enter the tank dimensions.  You can experiment with the different tank types, and then  click "cancel" to exit back to the tank setup window.

Click the "VMI Settings" button.  This is where the alarm level settings are entered and customized for the color-coded VMI status zones explained previously.

Click the "Last Readings" button. The "Scale Factor" is units per gallon, and it can be changed to display any unit.
