Retrofit existing meters
Add remote data collection to installed gas meters still in service.
Retrofit smart gas-meter gateway
IPS-520/521
Gas Meter Gateway
A retrofit smart-meter gateway for Itron and Honeywell gas meters, with pulse metering, tamper detection and mobile connectivity
Itron / HoneywellNB-IoT / LTE-M10–15 years
Product role
Bring existing gas meters into remote data collection
IPS-520/521 counts consumption pulses, monitors intervention events in a sealable meter-mounted enclosure, and communicates with the head-end system over NB-IoT or LTE-M
Gas meterPulse output
IPS-520/521Pulse counting, health monitoring and data transfer
NB-IoT or LTE-M
Head-end systemConsumption data, logs and alerts
Typical applications
Retrofit data collection without replacing the meter
Pulse and status data from the existing gas meter reach the head-end through a direct mobile connection
New meter deployment
Add communications to Itron RF1 and Honeywell BK-G4 meters.
Consumption data collection
Log pulse values and forward them to the head-end on schedule.
Tamper and health monitoring
Report magnetic interference, motion, opening and battery status.
Consumption alerts
Monitor blockage, leakage and Qmin/Qmax thresholds.
01 / 07
Key capabilities
Metering, monitoring and communications in one sealable unit
Meter fit, sensors, battery and NB-IoT/LTE-M connectivity form one field device
Meter-specific enclosure
Special plastic housing with a separately sealable maintenance door.
Multiple sensors
Consumption pulse, magnetic tamper, motion, opening and temperature.
Long battery life
10–15 years depending on messaging frequency, with replaceable battery.
Direct mobile connectivity
NB-IoT and LTE-M radio with broad band support, including B31/B72 options.
Scheduled and event-driven transfer
PUSH heartbeat, logs and alerts, plus response-based PULL operations.
Head-end integration
ABL or DLMS/COSEM message formats with an extensible protocol framework.
