Pulse emission
Pulses are emitted at 1-second intervals. The number of pulses to be emitted is calculated every second. Pulses are
emitted in bursts with a pulse duration of 2
…
5 ms and pauses depending on the current pulse frequency. The duration
of the pauses between the individual bursts is approx. 30 ms.
The transmitted pulse signal is the average determination of a series of flow measurements. This means that there will
be a transient phenomenon until correct flow signal has been obtained during start-up. Furthermore, this brings about a
pulse tail of up to 8 seconds in case of sudden hold.
