Meter Setup
307 Flow velocity offset 0 m/s -10 to 10 m/
s
HW key Velocity added to measured flow velocity
310 Calibration factor 1.0 0 to 2 R/W This calibration factor will be calculated at
the factory with wet-calibration.
For FUS080-SONOKIT (retrofit) installations
this parameter should be calculated by the
pipe geometric tool (see "Pipe geo. assis‐
tant" in "Device" menu)
311 Adjustment Factor 1 - 2 to 2 R/W Meter correction factor for customer adjust‐
ment of the calculated flow value. Can be
used at installations where a reference meter
is used to get reference to the true flow rate
312 Sensor cable length Product de‐
pendent
0 to 200 m R/W Cable length (m) from sensor to transmitter
372 Filter time constant Product de‐
pendent
0 to 100 s R/W General time filter for flow measurement. Fil‐
ter constant is the time that must pass before
the filter's ouput value is at 70% of the
change of its input value. Higher number
gives a slower and more stable flow signal.
373 Low flow cut-off Product de‐
pendent
0 to 10 R/W If the flow comes below this percentage of
Qmax, then the flow value is set to zero
374 Creep lock max number 10 0 to 20 R/W Alternative cut-off for totalizing and pulsing.
If the totalized flow within this number (N) of
samples exceeds [(N x Qmax x low flow cut
off)/100], the amount is accepted for pulsing.
ΣQ > N x Qmax x low flow cut-off/100
● ΣQ: totalized flow within N samples
● N: Creep lock max number
380 Protect linearization from
user access.
No No, Yes Read Protection of the linearization parameters. It
is decided by the order number and cannot
be changed.
The linearization parameters are listed in the
device menu "Linearization"
