User manual for flow meter with pulse input SPI-94
6.2.
DETECTION OF THE PEAK VALUES
The
SPI-94
flow meter is equipped with peaks detection function. It can detect a peaks of
the input signal and display their values. Presets connected with this function are placed in
”HOLd”
menu (see description of
”HOLd” menu
). The detection of the peak can be done if
the measured signal raises and drops of value at least equal to parameter
”PEA”
. Detected
peaks are displayed during the time defined by parameter
”timE”
. If a new peak will be
detected while one is displayed, this new peak will be displayed and display time counter will
be cleared
(Figure 6.2). If no peaks are detected while time
”timE”
elapses
,
device starts to
show the current value of input signal again.
The relays/LEDs and the current output can be controlled depend on the current value of
input signal or the peak value (see
”HOLd” menu
).

CONTROL OF THE RELAY OUTPUTS
The control of the object (measured signal) is done due to instantaneous flow value
(current flow rate) or total flow counter value
, and
is realized via relay outputs. Front panel
LEDs named „
R
” indicates the state of particular relay output.
If device is not equipped with one or more relay outputs, menus refer to this relays
are available, but apply to LED indicators only. In such case LEDs indicates
exceeding of particular thresholds.
