Waterpilot FMX21 Description of device parameters
Hauser 97
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
Write permission Operator/Maintenance/Expert
Description Select the calibration mode.
Options • Wet
Wet calibration is performed by filling and emptying the vessel. In the event 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.
Note • In the case of wet calibration, the level (e.g. vessel empty or partially filled) must actually
be available. 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. For the "In height" level selection, the associated height must be
entered in the "Empty height" parameter.
Factory setting 0.0
