ELECTO SJ Multi — Precise Measurement and Automatic Remote Reading
Maddalena ELECTO SJ Multi is an electronic single-jet water meter combining accurate water consumption measurement with integrated Wireless M-Bus / OMS and LoRaWAN communication.
The DN15 / R160 / L110 / T50 variant is designed primarily for cold-water measurement. The electronic register, local data storage, and built-in radio module enable automatic collection of readings without physical access to the water meter.
R160 Accuracy, Two Radio Standards and Long-Term Operation
R160
The high measuring range ratio allows accurate recording of consumption even at low water flow rates.
wM-Bus + LoRaWAN
A single water meter can work with both a local Wireless M-Bus system and long-range LoRaWAN infrastructure.
Minimum 13 years
The manufacturer declares a minimum battery life of 13 years in the dual configuration, depending on radio settings.
Automatic Cold-Water Consumption Measurement
Water Meter Designed for Cold Water
The T50 temperature class defines a water meter variant intended for a medium with a maximum temperature of 50°C.
This is the main difference compared with the T30/90 variant, which is designed to operate with higher-temperature water within the range 30…90°C.
DN15, Q3 2,5 m³/h and Measuring Range Ratio up to R160
Measuring Range Ratio Depending on Water Meter Orientation
For the DN15 / Q3 2,5 m³/h configuration, the manufacturer specifies a maximum measuring range ratio of R160 in the appropriate horizontal mounting position.
In other mounting orientations, the maximum measuring range ratio is correspondingly lower, so the installation method should be considered when designing the measurement system.
Controlled Measurement Error Across the Entire Flow Range
U0-D0 Class Simplifies Installation in Confined Spaces
The water meter 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 shafts and small installation spaces.
Wireless M-Bus / OMS and LoRaWAN in One Water Meter
Wireless M-Bus
It enables local and mobile meter reading and cooperation with compatible concentrators.
OMS
OMS support improves interoperability with other automatic utility-reading infrastructure components.
LoRaWAN
Long-range communication enables data to be sent to a central system without local meter reading.
Mobile Reading and Continuous Monitoring
The multiprotocol radio module enables both Wireless M-Bus and LoRaWAN infrastructure to be used.
This allows the water meter to be deployed in an existing reading system and later integrated into an extensive telemetry infrastructure without replacing the meter itself.
More Than 11 000 Stored Values
The electronic register stores more than 11 000 historical values, enabling analysis of the consumption profile and changes occurring in the installation.
Historical data can support billing, installation diagnostics, and identification of unusual water consumption patterns.
The water meter also monitors anomalies
IP68 for Indoor and Outdoor Use
IP68
The rotatable electronic register has a high level of protection against water and environmental factors.
IP68 — 720 h
For the Multiprotocol version, the manufacturer specifies IP68 protection tested for 720 hours.
UV Protection
The display and cover have UV protection, supporting outdoor applications.
Minimum 13 years of operation in dual mode
ELECTO SJ Multi has a built-in lithium battery and does not require wired power to be supplied to the measurement location.
Maddalena declares at least 13 years of operation in the dual configuration. Actual battery life depends on communication configuration and transmission parameters.
110 mm Installation Length
Key Parameters DN15 / R160 / L110 / T50
* Battery life depends on the selected radio configuration, transmission frequency, and operating conditions.
ELECTO SJ Multi in a Remote Reading System
The Multiprotocol version enables local Wireless M-Bus reading and automatic long-range LoRaWAN transmission.
