4206 PULSATING FLOW
• If flow is characterized by severe fluctuations as is the case, for example, with
reciprocating pumps, flow components outside the measuring range are
buffered, balanced and output after a maximum delay of 60 seconds.
If the buffered data cannot be processed within approx. 60 seconds, a
fault/notice message appears.
• Under certain plant conditions, flow values can aggregate in the buffer, for
example in the case of prolonged and unwanted fluid backflow. However, this
buffer is reset in all relevant programming adjustments which affect the
frequency output.
