Waterpilot FMX21 Description of device parameters
Endress+Hauser 89
Description Select the height unit. The measured pressure is converted to the selected height unit
using the "Adjust Density" parameter.
Prerequisite "Level selection" = "In height"
Options • mm
• m
• in
• ft
Factory setting m
Calibration mode

Description Select the calibration mode.
Options • Wet
Wet calibration takes place by filling and emptying the vessel. In the case of two
different levels, the level, volume, mass or percentage value entered is assigned to the
pressure measured at this point in time ("Empty calib." and "Full calib." parameters).
• Dry
Dry calibration is a theoretical calibration. For this calibration, you specify two pressure-
level value pairs or height-level value pairs via the following parameters: "Empty calib.",
"Empty pressure", "Empty height", "Full calib.", "Full pressure", "Full height".
Factory setting Wet
Empty calib.

Description Enter the output value for the lower calibration point (vessel is empty). The unit defined in
"Output unit" must be used here.
Note • For wet calibration, the level (e.g. empty or partially filled vessel) must actually be
present. The associated pressure is then automatically recorded by the device.
• In the case of dry calibration, the level (vessel empty) does not have to be available. For
the "In pressure" level selection, the associated pressure must be entered in the "Empty
pressure" parameter. The associated height must be entered in the "Empty height"
parameter for the "In height" level selection.
Factory setting 0.0
