User manual for - FLOW METER SPP-N118
Figure 6.3. Switching between digits (screens) of total flow result.
All accessible parameters (e.g. pulse input settings, decimal point position) can be
changed by entering the menu (see:
DEVICE PROGRAMMING
). Use the local keyboard or
the remote controller to do it. (Note: all parameters can be remote changed via RS-485
interface).
Counting of pulses and controlling or relays is realised regardless of operation mode
(after entering to menu mode counting and controlling is continued in “background”.
6.2.
DETECTION OF THE PEAK VALUES
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 6.4). If no peaks are detected while time
”timE”
elapses
,
device starts
to show the current value of input signal again. If „
HdiS
”=”
HOLD
” then setting parameter
"timE"
=
0.0
causes holding peak value until
[ESC]
button is pressed.
If „
HdiS
”=”
rEAL
” then
value
"timE"
=
0.0
means no holding. Displaying peak value is signalized by flashing most right
decimal point.
The relays/LEDs can be controlled depend on the current value of input signal or the
peak value (see
”HOLd” menu
).
