Relay trigger level settings
The switching behavior depends on whether the switch-on setting is set higher or
lower than the switch-off setting: threshold behaviour (ON > OFF) or as an in-range
alarm (ON < OFF).
Pos-Total Impulse

The Portable FlowShark Pulse has been configured to process the
impulses that have accumulated within the memory cycle
immediately. If the measurement time is insufficient, the unit will
switch over to permanent mode until all the impulses have been
processed. Therefore, it is important to modify the number of
impulses according to the maximum volume expected.
For example:
If the measurement cycle is 5 minutes, the duration is 0.5 seconds,
the volume is 1 m
3
, and the measured flow rate is 100 l/s…
5 minutes x 60 seconds x 100 liter per second / 1000 = 300
impulses x 0.5 seconds = 150 seconds
The Portable FlowShark Pulse will operate in the permanent mode
for the calculated period.
