Flow Sensor Parameters
[F=(K-Q)/60 - a]:
the internal calculation of the flow
rate is carried out according to the indicated formula. The following terms of
this formula can be parameterized:
➢
K Factor (‘K’)
[
1…
660
…65535
] [
x1 pulses/L
]: constant provided by the flow
meter manufacturer. For the flowmeter the K Factor is 660 pulses/L.
➢
Error Correction (‘a’)
[
0…
7
…255
] [
x1 Hz
]: Correction factor given by the
flow meter manufacturer.
It is recommended to read ANNEX I. Flow calculation carefully in order to
correctly configure the two previous parameters
.
Important
: Although other models can be parameterised,
the flow meter
function is only guaranteed for the water flow sensors provided by
Zennio
.
Sending Mode for Flow
[
Disabled
/ Periodic / With Value Change / Periodic
and with Value Change
]: analogous to the same parameter of the
“Configuration” tab (see section 2.3.1) applied to the channel being configured.
Listed below are the
objects
that appear when each
channel
is enabled:
“[Water][Chx] Flow”:
stores the amount of water flowing through the
corresponding channel per unit of time
“[Water][Chx] Disable”:
1-bit objects to enable/disable measurements and
sendings of the corresponding canal.
“[Water][Chx][RT] Consumed Water”.
See section 2.3.2.1.
2.3.2.1
TOTAL REGISTER
The total registers store the accumulated water consumption data from a single channel
since the device commissioing.
