Parameter
Description
Frequency flow
threshold
This is the threshold value for pulse frequency. If the received value is less than
the configured threshold, it is deemed to be zero.
Pulse input
rollover
When the meter is selected as a Pulse Meter, one of the input variables
transferred from the programmable logic controller is Pulse Count value. This is
the number of pulses transferred from the Pulse Meter or the High Speed
Counter module. This parameter sets the value at which the pulse count will
rollover to zero. It is essential that this value match the actual pulse rollover used
in the field by the pulse meter or counter module, otherwise the flow calculation
will generate unexpected values. Enter this value as (maximum value)+1.
Master pulse-
count rollover
This is a value that is 1 greater than the highest value that master pulse counters
will contain. Enter 0 for free-running counters which rollover to 0 from
4294967295.
Pulse flow
threshold;
count, time (s)
The first field should be 0 or a number between 2 and 20. The default is0.
The second field should be 0 or a number between 5 and 60 in seconds. The
default is 0.
K-factor
(pul/m3)
A number between 0.1 and 1.0e+8. The default is 1.0. Units show is the setting
of “Flow input unit” of the “K-factor Characteristics” panel shown in the previous
screen example.
