Battery-powered remote reading module for Elster / Honeywell BK G2.5–G25 diaphragm gas meters with GSM/4G LTE communication.
CF810-B adds reliable remote gas meter reading to compatible diaphragm gas meters. The unit mounts directly onto the meter, detects consumption pulses, stores meter data locally and transmits readings to a central system through its integrated GSM/4G LTE communication module.
Up to 10 years of battery operation – reduced field maintenance.
GSM/4G LTE connectivity – remote transmission of readings and alarms.
Tamper detection – magnet, enclosure opening and sensor disconnection monitoring.
Local data archive – readings remain stored during temporary communication loss.
Retrofit Remote Reading for Elster / Honeywell BK Diaphragm Gas Meters
CF810-B is compatible with the complete range of Elster (Honeywell) BK diaphragm gas meters from G2.5 to G25 and is designed for direct mounting onto the meter. This makes it suitable for retrofit projects where existing metering points need to be upgraded with automatic meter reading (AMR) and remote communication capability.
The integrated Hall sensor input provides reliable pulse detection with extremely low power consumption.
Automatic Gas Meter Reading and Data Logging
CF810-B stores consumption data locally so that meter information remains available even during temporary loss of mobile communication.
hourly and daily consumption logs;
totalizers with data integrity checking;
alarm and event history;
configurable reporting schedule;
data transmission once or up to four times per gas day.
CF810-B can therefore operate as a field component of an AMR gas metering system or a centralized gas consumption monitoring platform.
4G LTE Gas Meter Communication and Remote Configuration
The integrated communication module provides GSM/4G LTE connectivity for reliable data delivery to a central server or backend system. Device parameters can be updated locally or remotely, while diagnostics and reconfiguration can be performed without opening the enclosure or requiring specialized software at the metering point.
Tamper Detection and Alarm Reporting
CF810-B continuously monitors the metering installation and can generate alarms for:
magnetic interference;
enclosure opening;
sensor disconnection or removal;
configuration errors;
low battery condition.
