7.15 Flow
Two methods are available for flow measurement (volume flow, volume per unit of time): computation
based on a digital signal (signal type "Digital", e.g., rotary pulses of a paddlewheel) and the evaluation
of an analog signal (signal type "Analog signal").
NOTE!
For the "Digital" signal type, the signal must be fed in at a high-speed input (optional extra, see technical
data). The minimum frequency is 1 Hz, the maximum frequency is 12.5 kHz. If the frequency is < 1 Hz,
the flow value is set to 0.
