Menu / Parameters Description
Easy Setup
Language Used to select the menu language (Deutsch, English, Französisch, Spanisch, Italienisch, Chinesisch, Portugiesisch).
Unit Volumeflow Qv Used to select the unit for the volumetric flow rate (e. g. for the parameters QvMax / QvMaxDN and for the corresponding
process value).
Default setting: l/min
See Table Table 1: Units for the volume flow on page 53.
Qv Max 1 Used to set the full-scale value (measuring range = 0 to Qv Max 1 ) for the upstream and downstream volumetric flow rate.
Default setting: 1 x Q
max
DN
Unit Vol. Totalizer Used to select the unit for the volumetric meter and the pulse outputs.
Default setting: l (liter)
See Table Available units on page 53.
Pulses per Unit Used to set the pulses per volumetric unit or per mass unit and the pulse width for the “Pulse” operating mode of the digital
outputs. The pulse factor and pulse width are interdependent and are calculated dynamically (pulses per unit: 1 to 10000/s;
pulse width: 0.1 to 2000 mS).
Available only if a digital output has been configured as a pulse output and if volumetric flow or mass flow was selected as the
process variable to be output.
Pulse Width
Damping Used to select the damping.
The value set here (0.02 to 60 s) relates to 1 Τ (Tau).
The value refers to the response time to a sudden flow rate step change. The damping affects the actual value on the LCD
display and the current output.
Default setting: 1 second
Dig.Out 41 / 42 Mode Used to select the operating mode for the digital output 41 / 42.
• Off: Used to deactivate the digital output 41 / 42.
• Logic: Digital output 41 / 42 is used as binary output (e. g. as alarm output).
• Pulse: Digital output 41 / 42 is used as pulse output. In pulse mode, pulses per unit are output (e. g. 1 pulse per m
3
).
• Frequency: Digital output 41 / 42 is used as frequency output. In frequency mode, a frequency proportional to the flow rate
is output. The maximum frequency can be configured according to the full-scale value.
Default setting: Pulse
Upper Frequency Used to set the frequency for the full-scale value for the “Frequency” operating mode of the digital outputs. The entered value
(0 to 10500 Hz) corresponds to 100 % flow.
Available only if a digital output has been configured as a frequency output and if volumetric flow or mass flow was selected
as the process variable to be output.
Curr.Out at Alarm Used to select the state of the current output in the case of a fault.
The output “Low Alarm” or “High Alarm” current is configured in the subsequent menu.
Low Alarm Used to set the current (3.5 to 3.6 mA) for low alarm.
High Alarm Used to set the current (21 to 22.6 mA) for high alarm.
System Zero Used to start the automatic zero point calibration process with . The automatic zero point calibration process takes approx.
60 seconds.
Note
Prior to starting the zero point calibration process, make sure that:
• There is no flow through the sensor (close all valves, shut-off devices, etc.).
• The sensor is filled completely with the medium being measured.
