F.3.6 Bottom reference (P010)
This is the transmitter’s Bottom Reference setting. It is the distance measured vertically along
the ultrasonic beam path from the user preferred sensor reference point to the zero level of a tank
or an open channel (see Figure F-1 on page 137). It is not necessary to have the 4 mA output
start at the zero level, and the 4 mA starting pointing can be any liquid height above or below
this zero level.
Note
This parameter is important for calibrating and configuring the transmitter.
