Maddalena ELECTO SJ Multi DN15 / R100 / L110 / T50 is an electronic single-jet cold-water meter with built-in Wireless M-Bus / OMS and LoRaWAN communication. The DN15 variant has an installation length of 110 mm and a nominal flow rate of Q3 = 2,5 m³/h, a maximum operating pressure of 16 bar, and a measuring range ratio of R100.
Temperature Class T50 enables water measurement within the range 0,1…50°C. The electronic LCD register, storage for more than 11 000 historical values and extensive diagnostics enable consumption monitoring and anomaly detection. Integrated Multiprotocol communication allows the water meter to be used both in Wireless M-Bus / OMS systems and in permanent LoRaWAN infrastructure.

ELECTO SJ Multi — Consumption Measurement and Remote Reading in One Device
Maddalena ELECTO SJ Multi is an electronic single-jet water meter combining precise water consumption measurement with integrated Wireless M-Bus / OMS and LoRaWAN communication.
The DN15 / R100 / L110 / T50 variant is designed for cold-water measurement. The electronic LCD register, local data storage, and multiprotocol communication enable automatic reading without physical access to the water meter.
Accurate Measurement, Two Radio Standards and Long-Term Operation
R100
The R100 measuring range ratio enables accurate measurement across a wide range of flow rates, including low water consumption.
wM-Bus + LoRaWAN
A single water meter can work with both a local Wireless M-Bus / OMS system and a long-range LoRaWAN network.
13 years
The manufacturer declares 13 years of battery life for the device's factory dual configuration.
Automatic Cold-Water Consumption Monitoring
Cold-Water Measurement within 0,1…50°C
The T50 temperature class means the meter can measure water at temperatures from 0,1 to 50°C.
This variant is intended primarily for cold-water installations. The ELECTO SJ range also includes T30 and T30/90 versions.
DN15, Q3 2,5 m³/h and R100 Measuring Range Ratio
Accurate Recording of Low Flow Rates as Well
The R ratio defines the relationship between nominal flow rate Q3 and minimum flow rate Q1.
For this variant, Q3 is 2,5 m³/h, while the R100 measuring range ratio corresponds to a minimum flow rate Q1 of 25 l/h.
The ELECTO SJ family may also be available in other metrological configurations, so the R value specified for the particular variant should be considered when selecting the meter.
Accuracy Class 2
U0-D0 Class Simplifies Installation
ELECTO SJ has a U0-D0 flow profile sensitivity class.
This means no additional metrologically required straight pipe sections are needed directly upstream or downstream of the device, simplifying installation in confined spaces.
Wireless M-Bus / OMS and LoRaWAN in One Water Meter
Wireless M-Bus
It enables local and mobile data reading and cooperation with compatible concentrators.
OMS
OMS compliance supports interoperability with automatic utility-reading infrastructure components.
LoRaWAN
LoRaWAN enables continuous wireless data transmission over longer distances to a central system.
Flexible Smart Metering Infrastructure
* Manufacturer values for suitable radio conditions; LoRaWAN range up to 15 km applies to line-of-sight conditions.
More Than 11 000 Historical Values
The electronic register has a data logging function capable of storing more than 11 000 historical values.
Access to historical data allows the consumption profile, flow changes, and installation behaviour over time to be analysed, rather than only the current meter reading.
More Information Than Water Consumption Alone
Electronic LCD Display
The Multi version uses a 9-digit LCD showing the current water meter reading, flow rate, and device status information.
The electronic register is rotatable, allowing the display to be positioned for easy reading after installation.
IP68 and Design for Indoor and Outdoor Applications
IP68
The electronic register has a high level of protection against water and environmental factors.
720 hours
For the Multi variant, the manufacturer specifies IP68 protection tested for 720 hours.
UV Protection
The display and its cover are protected against UV radiation.
13 years of operation in factory dual mode
ELECTO SJ Multi uses a long-life lithium battery and does not require an external power supply.
For the factory Dual Mode configuration, the manufacturer specifies a battery life of 13 years.
Compact 110 mm Installation Length
Key Parameters DN15 / R100 / L110 / T50
* Actual battery life depends on communication configuration, transmission frequency, and operating conditions.
ELECTO SJ Multi in a Remote Reading System
The Multiprotocol version allows local Wireless M-Bus reading and continuous long-range LoRaWAN transmission to be used.
