Description
40151 311 Adjustment Factor 1 - 2 to 2 R/W Meter correction factor for customer ad‐
justment of the calculated flow value.
Can be used at installations where a
reference meter is used to get reference
to the true flow rate
40196 312 Transducer cable length Product
dependent
0 to 200 m R/W Cable length (m) from sensor to trans‐
mitter
40173 372 Filter time constant Product
dependent
0 to 100 s R/W General time filter for flow measure‐
ment. Filter constant is the time that
must pass before the filter's ouput value
is at 70% of the change of its input val‐
ue. Higher number gives a slower and
more stable flow signal.
40162 373 Low flow cut-off Product
dependent
0 to 10 R/W If the flow comes below this percentage
of Qmax, then the flow value is set to
zero
40164 374 Creep lock max number 10 0 to 20 R/W Alternative cut-off for totalizing and puls‐
ing.
If the totalized flow within this number
(N) of samples exceeds [(N x Qmax x
low flow cut off)/100], the amount is ac‐
cepted for pulsing.
ΣQ > N x Qmax x low flow cut-off/100
● ΣQ: totalized flow within N samples
● N: Creep lock max number
40184 380 Protect linearization
from user access.
No No, Yes Read Protection of the linearization parame‐
ters. It is decided by the order number
and cannot be changed.
The linearization parameters are listed
in the device menu "Linearization"
