Smart Water Meters and Utility Submetering

Cellular water meter: 4G LTE, no WiFi or gateway

The LoggerFlex Cellular Water Meter measures consumption ultrasonically, with no moving parts, and sends its readings over the 4G LTE network. There is no gateway, WiFi or wiring to install: once installed where there is 4G LTE coverage, the meter comes online and reports into the LoggerFlex app. The data SIM is built in and managed by LoggerFlex, so deployment is simply installing the meter and watching consumption appear on the dashboard.

• Ultrasonic transit-time measurement with no moving parts, so there is nothing to jam, wear or clog
• Class 2 accuracy (ISO 4064 / OIML R49) over a metrological range of R250
• Sealed lithium battery rated for 6 years, and an IP68 body for buried, flooded or outdoor installation
• Lead-free composite body, for potable water
• Two sizes, DN20 (3/4 in) and DN25 (1 in), with the same 4G electronics and managed data SIM

Leak alarms and consumption alerts

Readings arrive on a schedule: the Cellular Water Meter uploads once a day, and its leak, burst and fault alarms arrive with that daily upload. Set custom high-usage limits on weekly, monthly or rolling windows, and smart anomaly detection learns each meter's recent pattern and flags abnormally high use, so hidden leaks inside walls or in running plumbing fixtures are caught before they turn into water damage or an expensive bill. For fast leak alarms, add a flood sensor on an EDGE logger.

Submetering and fair cost allocation

Until water is metered, waste stays invisible and every bill is a guess. With per-unit data you can allocate shared water costs by unit or zone based on what each one actually consumes, where local rules allow. LF Cloud tracks consumption per unit, floor or zone, and usage data can be exported through the REST API or as Excel for your own reports.

Existing meters, gas, electricity and heat

Metering is not only for new meters: LoggerFlex turns legacy utility meters into web-based systems with leak detection, consumption analysis and automated submetering. Heat meters can be integrated alongside water and electricity for a complete consumption profile, and electricity usage anomalies are flagged the same way as water. For existing meters with a 4-20 mA or Modbus output, BLOCK ANALOG 4-20 mA and the Modbus bridge bring the readings into LF Cloud (the BLOCK Pulse Counter is being retired and the WiFi Water Meter is withdrawn).

One platform for every meter

Every reading lands in the LoggerFlex dashboard and mobile app: automatic remote reads, submetering by unit or zone, custom consumption alarms, leak and continuous-flow alerts, sharing with unlimited users, and trends, charts and Excel export. Data and servers are in Canada. LoggerFlex is a Canadian IoT manufacturer with US-patented technology and more than 50,000 devices deployed.

Frequently asked questions

What types of utility meters can LoggerFlex read?

LoggerFlex reads pulse-output and Modbus RTU meters as well as 4-20 mA signals, which covers most electricity, water, and gas submeters. The device captures consumption data automatically and reports it to LF Cloud for billing and analysis.

Do I need a gateway or extra network hardware for submetering?

No. WiFi models join your site's existing WiFi network, and the Cellular Water Meter has a built-in 4G LTE data SIM managed by LoggerFlex, so either way there is no separate hub to buy, power, or maintain. That lowers the cost and complexity of rolling out submetering across a building or portfolio.

Can the data support tenant billing and cost allocation?

Yes. Continuous, time-stamped consumption records in LF Cloud let you allocate utility costs by tenant, unit, or zone, and export the data you need for invoicing and reporting.

Where is metering data stored and how secure is it?

Metering data travels over TLS to LF Cloud, whose servers are only in Canada (Montreal); data from every meter goes directly to them.
