I_ _ _ _ Err

Backflow

Reverse flow detected, a flow in 

opposite direction is detected.

The error activates after continuous 

reverse flow higher than 20 liters.

Check water network and the 

meter installation.

Reset the alarm via LoRa 

downlink (if in LoRa version) or 

directly on field 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

Overflow

Water meters was used in an 

improper condition, flow rate 

exceeded the operating conditions. 

Manufacturer warranty expires.

The error activates after the meter 

operates at a flow 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 field 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 flow rate of the meter stays 

continuously over Q3 for 30 minutes 

the alarm is set.

Check water network.

The alarm automatically resets 

when the flow 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 flowing in the 

opposite direction. This is probably 

due to a wrong installation.

During first installation only, if the 

absolute counter (forward counter - 

reverse counter) is equal to 0 and a 

reverse flow (>8 Liters) is detected, 

the alarm turns on.

Check water meter installation.

Automatically resets when flow 

is on the correct direction.

The payload contains the status of the alarm 

and when flow direction turns to the correct 

one the status updates.

_ _ _ _L Err

Leakage

A continuous flow for a long time is 

detected. This is probably linked to a 

leakage in the water network.

The meter detects a continuous flow 

of >0.5*Q1 for 12 hours.

Check water network\system\ 

taps against leakages.

Resets automatically when a 

flow 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.

Device end-life – the icon                is shown one year prior the complete battery discharge or one year prior 

to the device end life cycle.

Contact the manufacturer for a replacement. 

Warning: 

the  meter  is  equipped  with  non-rechargeable  batteries,  that  can  be  dangerous  when  used 

improperly. To reduce the risks, it is necessary to respect the following precautions:
- Don’t recharge the battery;
- Don’t put the battery in short circuit;
- Don’t expose the battery at temperatures higher than 85° C;
- Don’t put inside ovens, crush or cut: these actions could cause an explosion or a leakage of flammable 
  gas or liquids;
- Don’t use open flames near the meter;
- Don’t expose the battery to extremely low-pressure environment which could cause an explosion or a 
  loss of flammable gas or liquids;
- Always dispose the batteries in compliance with current regulations
- Always use original spare parts authorized by the manufacturer.
