13.4.3 Saddle Tank Load Cells
The saddle tank has dedicated load cells so the
actual weight of the saddle tank can be monitored
to ensure correct product application rates based on
the actual weight leaving the tank.
a. Calculated Weight Remaining (A) - Is the
theoretical weight remaining in the tank based
on taking the starting weight and calculating
how much has left based on the revolutions
detected by the metering auger and the
metering auger calibration factor.
b. Measured Weight Remaining (B) - Is the
actual load cell weight remaining in the tank.
c. Pressure Compensation - the saddle tank
with dedicated load cells has a pressure sensor
installed to measure the air pressure inside the
tank. This is used to correct for the weight
that is taken off the load cells when the fans
pressurize the tank. There is a default pressure
compensation factor entered in the settings
but if you notice that the weight changes
substantially when the fans are turned on you
can adjust this factor to keep the weight more
consistent. Refer to Section 6.6.7 - Weigh
Scale.
Note
The most accurate load cell weight for the saddle
tank will be when the fans are shut off and there
is no pressure inside the tank.
13.4.3.1 Scale Weight Difference
The Scale Weight Difference alarm will tell you
if the Measured Weight in the tank differs from
the Calculated Weight outside of the Threshold.
This applies for the saddle tank with dedicated
load cells to tell you if something is out with that
tank. It also monitors if the total weight of the
tank differs from the combined Calculated Weight
Remaining in each tank. If this alarm occurs refer
to Section 12 - Troubleshooting.
