Function - Kamstrup ULTRAFLOW 54 Technical Description

TECHNICAL DESCRIPTION

8.6 Function

In the meter's working range from min. cut-off to saturation flow there is a linear connection between the water
volume flowing through and the number of pulses being emitted. An example of the connection between flow and
pulse frequency for ULTRAFLOW

If the flow is lower than min. cut-off or negative, ULTRAFLOW
At flows above the flow corresponding to pulse emission at a max. pulse frequency of 128 Hz, the max. pulse
frequency will be maintained.
Table 19 overleaf shows the flow at max. pulse frequency 128 Hz for the various flow sizes and meter factors.
