1. General information This instruction designed for ultrasonic heat
meter SonoMeter 30 flow and energy verification
and calibration.
Heat meter energy measurement error (δEs)
assess the application of the partial verification
method: assesses the calculator thermal energy
measurement error (δE), the flow volume
measurement error (δV) and temperature sensor
temperature difference measurement error (δT).
Heat meter energy measurement error (δEs) are
all components of the arithmetic sum of the
errors:
Es = ׀
E׀
+ ׀
T׀
1) Energy pulse out terminals (Fig. 1) connected
to the pulse counter (not required when
reading the measurement results directly
from the display or via a digital interface)
Pin 53 - Energy Pulse output (Pulse)
Pin 52 - Energy Pulse output (GND)
2. Test instruction
2.1 Calculator energy
measurement error (δE) test
2) Temperature sensors placed in the
temperature testing bench (for temperature
difference simulation).
3) Verification mode is activated by connecting
TEST jumper contacts 1 (FIg. 1).
4) Determination errors:
- before each measurement run automatic
verification mode with long button clicking
on the meter (simulated flow pulses),
- When the LCD display stops blinking “TEST”,
energy and volume values can be read
directly from the LCD screen or through the
optical / digital interface. The pulses shall
begin calculated with the corresponding
nominal flow pulse values as follows:
Permanent flow qp
(m3/h)
Energy pulse value,
(Wh/imp)
0.6 0.1
1.0 0.2
1.5 0.2
2.5 0.5
3.5 0.5
6.0 1
10.0 2
15.0 5
- energy E (kWh) measurement error is
calculated by formula:
E = (E – E
0
) / E
0
• 100 %
there:
E0– the conventional true energy E value
(kWh), calculated in consideration of the
fluid temperature values simulated Θ1, Θ2
and simulated change in volume values:
Flow sensor mounting
place E0calculating formula
Supply pipe E0=V1 • ρ1 • (hT1-hT2)
Return pipe E0=V1 • ρ2 • (hT1-hT2)
There:
E0– the estimated true value of the energy component
(kWh);
V1 – simulated water volume value (m3);
ρ1…ρ2 – density of water, corresponding to the sumulated
temperature value Θ1,Θ2, (kg/m3);
hT1… hT2 – relative enthalphy of water, corresponding to the
simulated temperature value Θ1,Θ2

when the measurement results are directly
reading from the display or via a digital
interface)

2) Switched on verification mode by connecting
TEST jumper contacts 1 (1 pav),
3) The meter mounted on the flow test bench,
flow are simulating.
Recommended minimum pulse content and
measurement time:

0.1 qp <q ≤ qsN≥1000 T> 1 (min)
qi ≤ q ≤ 0.1 qpN>500 T > 1 + 8 qi/q, (min)

It must be maintained both minimum time and
minimum pulse quantities.
4) After the simulation of flow measured volume
V (m3) value is read directly from the display
(or through a digital interface) or calculated
pulse counter calculates the volume pulse
multiplied by the pulse value:
Permanent flow qp, (m3/h) Volume pulse value, (l/imp)
0.6 0.001
1.0 0.001
1.5 0.001
2.5 0.002
3.5 0.01
6.0 0.01
10.0 0.02
15.0 0.02
- volume V (m3) measurement error calculated
by formula:
V = (V – V0) / V0 • 100 %
there:
V0– device true value of simulated volume (m3).
3. Calibration instruction
3.1.1 Calibration mode
To enter calibration mode it is necessary to
connect the verification jumper 1, remove
metrological seal and short circuit calibration
contacts 2. (Fig.2).
3.2 Software installation The software “SonoMeter30Config.exe” is used
to read and configure SonoMeter 30 device via
OG-1-USB optical reader.
Meter configuration / calibration cab be made
also via M-Bus interface module then converter
COM/M-Bus (MB-1) can be used.
Open “SonoMeter30Config.exe”. Press “Next”.
Then, you can choose installation directory.
“SonoMeter30UserConfig” has five user interface
windows for different purposes:
• “Actual” – actual data window;
• “LCD Menu” – LCD configuration window.
• “Configuration” – configuration window for
pulse channels, archive and tariffs;
3.3 Program interface • “Archive” – window for information from
device archive;
• “Manufacturer” – device calibration, reset and
configuration window.
2.2 Volume measurement

Measurement units, flow pipe tagging,
calibration can be configured in “Manufacturer”
window.
Select energy units option in “energy unit” field
3.5 Volume calibration and press “set” in order to configure what energy
units are used for measurements. If device is
successfully configured message “Operation
done” will pop up.
If device is going to be placed on flow pipe, tag
“Flow pipe”. If device is going to be placed on
return pipe, tag “Return pipe”. Press “set” to save
configuration into device. If device is successfully
3.5.1 Changing pipe type configured message “Operation done” will pop
up. If is it needed that device measure only
heating energy, “heating only” box should be
tagged.
Press “Read” and then press “Manufacturer Reset”.
Disconnect the battery from the device. Use a
jumper to short the contacts on the device for
3.5.2 Resetting device 3 seconds in place where need to be connect
the battery. Connect a battery to the device and
reconfigure the date and time parameters.
Place jumper under removed device cover
(see Fig. 4). Press “Read” and then write error
“Err %” and flow “Q” data. Press “set” to save
3.5.3 Calibration configuration into device. If device is successfully
configured message “Operation done” will pop
up.
