By looking at figure 6 we see that the original value for the large canister’s
reference magnet is 3CF40. (This is also reference [E] in figure 2)

Original Value For The Large
Tank Reference Magnet
Figure 6: Level Sensor Data Screen; All Magnets Functioning Normally
If the float sensor in the large tank malfunctions, it will not send a response to the
transducer rod. Consequently, the software will mistake the response from the large
tank’s reference magnet (the fourth magnet) for the large tank’s float sensor (the third
magnet). This is easily recognizable because the large tank’s float sensor now displays
a value that is in the range of the large tank’s reference magnet. Figure 7 illustrates how
the response is placed on the screen.
