4.5 Measured value damping
The damping time [dAP�F] allows to set after how many seconds the output signal
has reached 63 % of the final value if the flow value changes suddenly� The set
damping time stabilises the switching outputs, the display and the process value
transfer via the IO-Link interface�
The damping time is added to the response time of the sensor (→ Technical
data)�
The signals [UL] and [OL]
(→ 12)
are defined under consideration of the damping
time�
4.6 Low flow cut-off
With the function low flow cut-off [LFC] it is possible to suppress small volumet-
ric flow quantities� Flows below the LFC value are evaluated by the sensor as
standstill (Q = 0)�
4.7 Simulation
With this function, the process values flow, temperature and meter reading of the
totaliser are simulated and their signal chain is reviewed�
When the parameters cr�UL, UL, OL und cr�OL are set, the process values that
lead to an error message or warning can be simulated
(→ 12)
�
When the simulation is started, the values of the totaliser are frozen and the
simulated totaliser is set to 0� The simulated flow value then has an effect on the
simulated totaliser� When the simulation is ended, the initial totaliser values are
restored�
The simulation does not have any effect on the currently existing process
values� The outputs operate as previously set�
During the simulation the original totaliser value remains saved without any
changes even if there is a real flow�
During the simulation operation, no error message of the currently real
application is available� They are suppressed by the simulation�
