Selection of submenu '...Units' using
Select the damping.
The value set here (0.02 to 60 s) refers to 1 τ (Tau). The value refers to the response time for a step flowrate
change. It affects the instantaneous value in the display and at the current output.
Default setting: 1 second
Switches the damping on or off.
If the flow count and display are performed using mass flow units, a fixed density value must be included in the
calculations. To convert to mass flow, a density value in the range of 0.01 to 5.0 g/cm3 can be set.
Selection of submenu '...Cut Off' using
Entry of the measuring point tag for the transmitter.
Alphanumeric, max. 20 characters
Enter the tag number for the transmitter.
Alphanumeric, max. 20 characters
Tx -> Sens
The settings are redundantly saved in two data modules. One of them is the SensorMemory, the other is the
transmitter motherboard (backplane).
By selecting 'Tx -> Sens', location-specific settings such as measuring range or damping are replicated from
the transmitter motherboard (backplane) to the SensorMemory.
Sens -> Tx
By selecting 'Sens -> Tx', location-specific settings such as measuring range or damping are replicated from
the SensorMemory to the transmitter motherboard (backplane).
For service purposes only. Restart the device without having to switch the power supply on and off.
All user-accessible parameters will be reset to the factory default settings.
Selection of submenu '...Feature Settings' using
Selection of submenu '...System Zero' using
Activates the filter technology for noise reduction.
Filter: Off, Filter 15, 30, 60 (15: lower filtering, 60: strong filtering)
Filter setting affects 20 mA signal (damping).
Default setting: Off
Enables improved measurement performance, especially in piston pump applications.
• Filter On/Off: On/Off
• Filter length: 3 to 30 sec
• Strokes per minute: Indicates the piston pump strokes per minute
