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.

Empty Tank Detection Area
The Empty Tank Detection Area defines a range within a lower limit of 200 mm (8 in.)
above the tank bottom. If the surface echo is lost in this region, the tank is considered
empty (the device enters Empty Tank State) and the level gauge presents a zero level
reading.
