MEASURING MODE
(4225)
!
Note!
This function is not available unless the PULSE setting was selected in the OPERATION
MODE function (4200).
Use this function to define the measuring mode for the pulse output.
Options:
STANDARD
Only positive flow components are totaled. Negative components are not taken into
account.
SYMMETRY
Positive and negative flow components are taken into account.
!
Note!
The direction of flow can be output via the relay output.
PULSATING FLOW
If flow is characterized by severe fluctuations as is the case, for example, with
reciprocating pumps, the positive and negative flow components are totaled, with the
signs taken into account (e.g. –10 l and +25 l = 15 l).
Flow components outside the maximum pulse number per second (value/width) 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 pulse output.
STANDARD REVERSE
Only negative flow components are totaled. Positive components are not taken into
account.
Factory setting:
STANDARD
