Filter length = 10
Level Filter Length
Level filter length
– The length of the averaging filter, in number of readings, to smooth the measured
values. The instrument performs 1 reading per second, so a filter length value of 10 will result in 10
seconds integration time. When using longer filter lengths, more measured values are used for filtering,
and the resulting data will be smoother. However, when the water level changes, it will take more time
for the new measurement to be reported. Typically, this parameter should be set to a value between 10
and 50. For highly turbulent water, longer filter length is recommended.
IIR Constant
IIR constant
- The constant used by Infinite-Impuls Response (IIR) filter if IIR filter type is selected.
Accepted values are decimal numbers between 0 and 1. When the IIR constant value is closer to 0.0, the
filter response will be slower. When the IIR constant value is closer to 1.0, then the filter response will be
faster.
