7.7 Level measurement
7.7.1 Preparatory steps
Open container
• The Deltabar S PMD75, and FMD77 are usually suitable for level measurement in an open
container.
• FMD77: the device is ready for calibration immediately after opening a shutoff valve (may or
may not be present).
• PMD75: before calibrating the device, the pressure piping must be cleaned and filled with
fluid. See the following table.
MAX. PRESS. FLOW
Enter maximum pressure of primary device.
(See also layout sheet of primary device).
MAX. PRESS. FLOW
Enter maximum pressure of primary device.
(See also layout sheet of primary device).
DAMPING VALUE
Enter damping time (time constant ). The damping
affects the speed at which all subsequent elements, such
as the onsite display, measured value and the OUT Value
of the Analog Input Block react to a change in the
pressure.
