Teaching Old Meters New Tricks
Sure, we make a comprehensive range of great meters.
But wouldn’t it be great if you could wave a magic wand and turn many of your old meters into smart, cellular AMI devices that deliver the detailed, minute-by-minute data that makes Metron metering so powerful?
Well you can.
Metron offers a variety of retrofit solutions which enable you to install Prism® registers on your existing third-party meters, giving them a new lease of life without the cost of replacing the meter bodies. Installation is quick and simple, and data starts flowing into WaterScope® immediately.
Retrofit Benefits
- Replace old mechanical registers to eliminate manual reads
- Replace radio-frequency registers to eliminate drive-bys or expensive infrastructure
- Minute-by-minute data provides deep insights into water use
- Leak detection alerts
- Irrigation violation reports
- Easy billing integration
Bring your old meters into the 21st century!
Data integration can go both ways
- If you’re deploying Metron meters and WaterScope is your primary water data platform (it should be – it’s the most powerful in the industry!), we can build integrations that pull data from third-party platforms into WaterScope.
- Or, if you prefer to use a third-party data platform, we can set it up to pull in data from your Metron meters and retrofitted meters.

Retrofit Adapters
For meters which couple magnetically to top-mounted registers, Metron has a range of adapter rings which make mounting Prism registers easy. Standard brass meters from major manufacturers can be retrofitted in this way, turning them instantly into smart cellular meters.
Contact Metron to find out if your meters are supported.


3-Wire Meters
For meters with an existing module or register that provides a standard 3-wire output, the cellular Prism R register connects directly to capture water flow data every minute of every day. The wires can be provided bare (as shown below) or terminated with a specific connector if required by the application.

Universal Duplexer for AMI Systems

Designed for situations where a meter is monitored by two AMI endpoints, the Universal Duplexer provides a reliable, robust connection from the meter to the primary endpoint, while allowing a second endpoint to also receive the 3-wire signal. This is ideal for approved third-party monitoring of water consumption for, say, an apartment complex, a mobile home park or an educational campus.
Paired with Metron’s Prism R monitor, this setup allows water data to flow into WaterScope without disrupting the function of the primary endpoint.
- The duplexer is designed to always prioritize the primary endpoint. Its 3-wire signal is passed through even when the duplexer’s battery expires or in the unlikely event of water ingress.
- The enclosure’s IP68 rating means that the duplexer continues working even when submerged.
- Long battery life – and a user-replacable battery – mean low maintenance.
