3.1.5.2 Meas.Direction Output of suppression of reverse flow
Affects all outputs, totalizers and display forw.+rev. • forward only,
• forw.+rev.
3.1.5.3 Hysteresis Hysteresis of detection of flow direction in
% of full scale value 0.2 % 0 to 20 %
3.1.6 Low flow cut Threshold for low flow cut in % of full scale
value 1, 2 or absolute value in flow unit 3 1 % 0 to 20 %
3.1.7 Noise filter
3.1.7.1 Fltr.Time Con. Time constant τ for measured value attenu‐
ation; after a jump in
the measuring variable, the output meas‐
ured value reaches about 99% of the new
setpoint after 5*τ
Does not affect totalizers. 3.00 s 0.0 ... 200.0 s
3.1.7.2 Line Synchron. Auto mode Not available
3.1.7.3 Noise Suppress
Suppress Time
Suppress Limit Values outside a tolerance range are evalu‐
ated for the duration of the blanking time
with high attenuation.
Time of effect of increased attenuation (0 s
= blanking off)
Tolerance range = floating a toler‐
ance value
0 s
