Figure 4-7. Bottom Echo Visible
Section 4. Configuration
Bottom Echo Visible if Tank is Empty
By using this function the level gauge will be able to track relatively weak
surface echoes close to the tank bottom by treating the bottom echo as a
disturbance echo. This function may be useful for products which are
relatively transparent for microwaves such as oil.
Before activating this function, you should use the WinSetup/Tank Scan
function to find out if there is a clearly visible echo at the tank bottom when the
tank is empty. If this is the case, the Bottom Echo Visible If Tank Is Empty
check box in the Empty Tank Handling window should be marked.
If the Bottom Echo Visible... function is disabled, searching for the product
surface echo is limited to a region close to the tank bottom (Empty Tank
Detection Area).
If there is no strong bottom echo interfering with the surface echo, mark the
Use Automatic Empty Tank Handling Settings check box to let the level gauge
automatically control the empty tank handling function.
