34 VEGAMET 514… D
Set-up, parameter adjustment
Parameter adjustment MST2, processing (flow)
With the scaling of MST2 the conditions for the signal
conditioning instrument is provided to calculate the
flow volume/time. The respective values for min. and
max. flow are generally stated by the flume
manufacturers or can be calculated as proximity
values (see page 29 … 32).
In case of calculation the value of min. flow is
unimportant.
Example relating to a rectangular flume (see page
31):
- Max. flow 1385 m 3 /h
- Min. flow 4,4 m 3 /h

Range 0 … (4) … 9999 (Min. flow)
–– 100 % corresponds to
1000
Range 0 … (1385) … 9999 (Max. flow)
This value (1385) is automatically transferred to the
menu point "Pulse parameter volume", see page 36
and 41.

value in the menu range "Parameter adjustment outputs", see menu points "relating to" and "Unit".
