F.3.20 Damping (P020)
The damping value is a time constant in seconds, and is applied as smoothing to the level
reading and the output current.
A larger value will have the effect of smoothing out rapid changes of level, and smooth out the
effects of turbulence and ripples on the liquid surface.
A value of zero can be edited, in which case no smoothing is applied and transmitter readings
immediately change the output. However, this may result in a rather ‘noisy’ output and is not
normally recommended.
Note
The pulse repetition frequency of the transmitter is one pulse per second, which means that the
system response time cannot be faster than this.
