Cx-Log1.1
A rugged, configurable logger for water and gas distribution networks. Measures flow and pressure at the asset, holds 3.5 years of readings, and reports over 4G with 2G fallback — from a single meter point to a network-wide deployment.
Measure, log, report, alarm.
Four jobs, each of them yours to configure. The settings trade against each other — faster sampling costs battery and data — so nothing is fixed in firmware you can’t reach.
Sampling from once a second to once every 24 hours. Faster sampling shortens battery life and raises data cost, so the rate is yours to set per channel.
3.5 years of history on the primary channel, plus a secondary fast-logging channel for pulse counting, a MODBUS register or a 4–20 mA input.
Transmit on a fixed interval, or in up to five programmable slots a day — set to balance data freshness against battery and data cost.
Up to five threshold alarms on any logged value, minimum or maximum, with hysteresis and persistence. SMS to as many as eight numbers.
Fits the metering you already have.
Four ways to feed it, on a primary and a secondary logging channel. If your meter has a pulse output, a MODBUS RTU interface or a 4–20 mA signal, the logger reads it — no meter replacement, no adaptor project.
Potential-free pulse input for flow counting, up to 100 pulses per second.
0–20 bar gauge transducer, mV/V four-wire, accuracy class <0.25 % FS. 303 stainless housing, FKM seal, ¼″ NPT process connection. Other ranges on request.
Configurable serial input — slave ID, register, data type and format, baud rate, parity and timeout all set from CLog.
Available as the secondary fast-logging channel, for any transmitter that speaks the standard loop.
Four ways to reach the device.
Internal 4G modem with automatic 2G fallback, so the device keeps reporting where coverage is thin. Readings are held on board and forwarded when the connection returns — an outage costs you nothing but latency.
Local connection for setup, diagnostics and configuration changes, without opening a cellular session. Commissioning takes about an hour per chamber, and it is the only visit the device needs.
Up to eight programmable numbers, delivered as the breach happens. M2M SIM dialling is disabled for security, and some M2M SIMs do not support it at all.
An authorised engineer walking or driving past the chamber collects the device’s readings straight into the mobile app — no cellular session, no lid opened, no chamber entry. Useful where signal is poor or a site is read on a round.

Configured and read from one place.
Every Cx-Log reports to CLog, where you register the device, set its channels, alarms and MODBUS parameters, watch its readings and pull its history. Nothing about day-to-day operation needs a site visit.
Take it away.
