VEGA VEGADIF 55 4 … 20 mA_HART - Manual (Page 64)

Measured value indication: S
elect Quick SETUP menu.
MEASURING MODE: S elect option "Flow".
POS. ZERO ADJUST: D ue due the installation position of the
instrument, a shift of the measured value can be caused. Correct the
MEASURED VALUE
via the parameter POS. ZERO ADJUST with the
option "Accept", i.e. assign the value 0 to the existing pressure.
MAX. FLOW: E nter the max. flow of the effective pressure transmitter
( see also construction sheet of the effective pressure transmitter).
MAX. PRESSURE: E
nter the max. pressure of the effective pressure
transmitter (see also construction sheet of the effective pressure
transmitter).
DAMPING VALUE: E nter the damping time (time constant τ). The
damping influences the speed with which all following elements such
as e.g. local indication, measured value and current output react to a
pressure change. Enter the damping time (time constant τ).
7 .6 Level measurement
Open vessel
VEGADIF
55 is used in all versions for level measurements.
Note:
VEGADIF
55 in flange version: After opening a probably existing block
valve, the instrument is ready for operation.
B efore you adjust VEGADIF 55 in basic version, you have to clean the
effective pressure lines and the instrument must be filled with the
medium.
