Measurement (parameters 300 and 334)
● Freely selectable volume and flow unit, where m
3
and m
3
/h is default in display. All other
units are displayed with a display label.
● Excitation frequency in battery operation (manually selected):
– Basic, max. selectable excitation frequency of 1/15 Hz
– Advanced, max. selectable excitation frequency of 6.25 Hz and sensor related
– MAG 8000 default excitation frequency with 2 D-cell battery pack is selected for typically
6 years of operation for MAG 8000 Standard (7ME6810) and MAG 8000 CT (7ME6820),
and 4 years of operation for MAG 8000 Irrigation (7ME6880).

● Excitation frequency with mains power follows maximum sensor excitation frequency
● Filter constant as numbers of excitations
● Low flow cut off, % of Qn (Q3)
● Empty pipe detection (active symbol on display when active)
● Filter selection for mains power frequency (50/60 Hz)
● Correction factor for change of flow direction or to adjust flow measurement
Data logger (Parameters 600 to 739)
● Logging of 26 records: selectable as daily, weekly or monthly logging
● Each logging includes:
– Consumption on totalizer 1
– Consumption on totalizer 2
– Alarm in current period (13 alarms)
– Meter status (8 values)
– Alarm on high or low consumption for selected logging period
– Totalizer 1 values for all 26 periods can be read on the display
