Operating Instructions, 11/2009, A5E00102775-07
Main flow direction related to direction
arrow on measuring tube (= forwards,
positive flow values)
Output of suppression of reverse flow
Affects all outputs, totalizers and display
Hysteresis of detection of flow direction in
% of full scale value
Threshold for low flow cut in % of full
scale value 1, 2 or absolute value in flow
unit 3
Time constant τ for measured value
attenuation; after a jump in
the measuring variable, the output
measured value reaches about 99% of
the new setpoint after 5*τ
Does not affect totalizers.
Values outside a tolerance range are
evaluated for the duration of the blanking
time with high attenuation.
Time of effect of increased attenuation (0
s = blanking off)
Tolerance range = floating average +
tolerance value
This is used when signals are severely
impaired, e.g. for media with a high solids
content or air locks
Totalizer forwards
Reset totalizer to zero and stop or start
Engineering unit of volume
or
Engineering unit of mass When you select
a unit of mass, entry of the actual medium
density is mandatory (menu 3.1.4)
Totalizer reverse
Reset totalizer to zero and stop or start
