environmental regulations in force.

7User Manual v1.4.5HYDRODIGIT-S1
Do not damage the device casing. In case of impact with external objects, the device can be
irreparably damaged and lose the IP65 or IP68 degree of protection. Install in areas protected
against impact. In case of breakage of the protective casing, contact customer support.
The water meter is not suitable for central heating and cooling systems. The water meter is
suitable for drinking water only.
Pay attention to sharp or edgy protrusions in threads, anges and measuring tubes. In this
regard, it is recommended to wear protective gloves.
After installing the water meter, perform a leakage test on the system.
Install or disassemble the meter only after depressurizing the system.
The meter does not have protection against lightning.
Do not expose the instrument to sunlight and other heat sources. Do not throw in the re.
The device must be used in a way that minimizes the potential for human contact during normal
operation. In order to avoid the possibility of exceeding the RF exposure limits, human proximity
to receivers with an integrated antenna should not be less than 20 cm (8 inches) during normal
operation.
Keep out of the reach of children.
The device does not require special protection against electrical interference; however,
electromagnetic interference must be avoided.
If transmission network interfaces are used, especially when cables are routed outside the
building, use increased protection against electrical interference.
If there is a possibility of frosting, empty the system and, if necessary, remove the meter.
Rinse the pipes thoroughly before installing the meter.
The meter must be installed with the direction of the arrow (visible on the lower part of the device)
matching the ow direction.
Avoid collecting air in the meter during the installation process.
The meter must not be subjected to mechanical strain when installed in the pipeline.
Install the meter in order to be protected from all impurities and contamination.
Remove the old gaskets and clean the sealing surfaces.
Grease sealing surfaces (use acid-free, potable water approved grease).
The device may only be installed in frost-free areas.

8User Manual v1.4.5HYDRODIGIT-S1
Fit only the supplied seals (seals must not obstruct the pipeline). The seals supplied must be t for
purpose and comply with local guidelines and directives. No liability is accepted for consequential
damages resulting from the use of third party seals, such as corrosion of sealing surfaces and
threads.
Clamp the meter ttings on both sides at the same time by hand and then tighten in opposite
directions using a suitable tool.
Slowly ll the piping with water after the installation is complete.
The meter must be protected against pressure shocks in the pipeline.

OPERATION
Note: the following display pictures are given as example.
DISPLAY
DELIVERY STATUS
The factory setting is the energy saving mode. In this mode the radio transmission function is not yet
activated, in order to save battery power during shipping and stock. However, the device can account the
consumption and send, if any, errors (e.g. reverse flow for incorrect installation).
OPERATING MODE – RADIO ACTIVATION
Once the water meter is installed, the radio transmission activates automatically after +/- 5 liters of water
passed through the device (LoRaWAN: starts sending Join requests – wM-BUS: radio is activated).
The display changes and the flow direction/level appear if the flow rate is detected.
RADIO PARAMETERS
Wireless MBUS compatible
As soon as radio operation mode is activated, the meter sends a radio telegram according to Wireless MBUS
T1 mode (unidirectional transmission).
Preconfigured Radio parameters (AMR Mode):
• Transmission frequency: every 200 seconds (current values).
• Transmission intervals: every day, from 0 to 24 h.
• Encryption: disabled (default).
• No historical data.
• Transmitted data: volume, actual date and time, reverse flow, alarms.

Error Type Descrizione Activation Troubleshooting Reset Radio telegram
I_ _ _ _ Err Backow Reverse ow detected, a ow in
opposite direction is detected.
The error activates after continuous
reverse ow higher than 20 liters.
Check water network and the
meter installation.
Reset the alarm via LoRa
downlink (if in LoRa version) or
directly on eld with IR interface
and B Metering software.
The payload contains the status of the alarm
and the date of the alarm activation. After
resetting it the status is updated and the date
will be removed from the radio payload.
_O_ _ _ Err Overow Water meters was used in an
improper condition, ow rate
exceeded the operating conditions.
Manufacturer warranty expires.
The error activates after the meter
operates at a ow rate higher than Q4
for 10 minutes continuously.
Check water network
parameters.
Reset the alarm via LoRa
downlink (if in LoRa version) or
directly on eld with IR interface
and B Metering software.
The payload contains the status of the alarm
and the date of the alarm activation. After
resetting it the status is updated and the date
will be removed from the radio payload.
_ _B_ _ Err Burst High consumption in a short term is
detected. This is probably linked to a
pipeline failure/break.
If the ow rate of the meter stays
continuously over Q3 for 30 minutes
the alarm is set.
Check water network. The alarm automatically resets
when the ow rate decreases
below 0,5*Q3
The payload contains the status of the alarm
and the date of the alarm activation. After the
alarm resets, the date changes to the date of
deactivation.
_ _ _R_ Err Reverse
installation
The meter starts owing in the
opposite direction. This is probably
due to a wrong installation.
During rst installation only, if the
absolute counter (forward counter -
reverse counter) is equal to 0 and a
reverse ow (>8 Liters) is detected,
the alarm turns on.
Check water meter installation. Automatically resets when ow
is on the correct direction.
The payload contains the status of the alarm
and when ow direction turns to the correct
one the status updates.
_ _ _ _L Err Leakage A continuous ow for a long time is
detected. This is probably linked to a
leakage in the water network.
The meter detects a continuous ow
of >0.5*Q1 for 12 hours.
Check water network\system\
taps against leakages.
Resets automatically when a
ow interruption happens.
The payload contains the status of the alarm
and the date of the alarm activation. After the
alarm reset the date changes to the date of
deactivation.
