Example:
With a set low flow of 0.5 %, the output is set to 0 as soon as the mass flow down-scales 0.5 % of Q
With a low flow hysteresis of 20 %, the actual value is issued again as soon as the mass flow up-scales 0.6 % of Q

Description
Sets the switching threshold for the low flow cut-off.
If the flow rate is below the switching threshold, there is no flow measurement. The setting of 0 % deactivates the low flow
cut-off.
Factory setting: 0.5 %
Sets the hysteresis for the low flow cut-off as it is defined in the parameter 'Low Flow Cut Off'.
Factory setting: 20 %
Sets the low flow for density.
Factory setting: 0.2 g/cm³
Indicates whether the DensiMass function is active.
Sets the device-specific code for activating the DensiMass function. To use this function subsequently, contact the ABB
service team or sales organization.
After entering the code, restart the device (e.g. using the parameter 'Device Reset' or by briefly switching off the power
supply).
Indicates whether the FillMass function is active.
Sets the device-specific code for activating the FillMass function. To use this function subsequently, contact the ABB service
team or sales organization.
After entering the code, restart the device (e.g. using the parameter 'Device Reset' or by briefly switching off the power
supply).
Indicates whether the VeriMass function is active.
Sets the device-specific code for activating the VeriMass function. To use this function subsequently, contact the ABB
service team or sales organization.
After entering the code, restart the device (e.g. using the parameter 'Device Reset' or by briefly switching off the power
supply).

NOTICE
Prior to starting the zero point adjustment, make sure that:
• There is no flow through the sensor (close all valves, shut-off devices etc.)
• The sensor must be filled completely with measuring medium for measurement.
