Pulse-Accu RT-NRT
This measured value is same as Accu RT-NRT. However, the threshold is deter-
mined by the resolution of the pulse output (0.05 mm · 0.1 mm · 0.2 mm · 0.5
mm · 1.0 mm).
The measured value is output as a pulse sequence using a rate of 5 Hz (default)
or 2 Hz (con figurable through the OTT Pluvio
2
S operating software via USB
interface).
Output delay: refer to Accu RT-NRT
Pulse factor (selectable): 0.05 mm · 0.1 mm · 0.2 mm · 0.5 mm · 1.0 mm
(1 mm =^ 20 · 10 · 5 · 2 · 1 Impulse(s))
Resolution: 0.05 mm · 0.1 mm · 0.2 mm · 0.5 mm · 1.0 mm
Recommended sampling interval: continuous pulse counting
Recommended storing interval: any time between 1 minute and 24 hours

Pulse status information
This measured value corresponds to the current bucket level and additionally
shows status information. Moreover, status information may be used as an
alive signal.
