Prism® Register
Our Spectrum® meters accurately and reliably track water usage, but there needs to be a way to record that data and transfer it into the cloud for WaterScope®. That’s where our Prism® register (also called a monitor) comes in. Fully digital and able to operate without interruption for over 20 years, the Prism connects automatically to the cellular network to upload water consumption data.
One-Minute Data Capture
The Prism register captures water flow rate data every single minute of every day. That’s 1,440 data points every 24 hours. With that level of detail, it’s possible to identify short-lived events such as toilet flushes and showers. No other vendor’s meter system offers this level of insight into water usage.
Daily Upload
24 hours’ worth of minute-by-minute data is uploaded in the middle of the night during a half-minute transmission to the local cellular tower, after which the data is immediately viewable in WaterScope. If a Prism register is configured to provide leak alerts, it won’t wait until the middle of the night: it will send a transmission immediately a leak is detected.
Compatibility
The Prism is compatible with all of Metron’s Spectrum meters* providing a common operational interface and data format. Prism registers are pre-configured to connect automatically to Verizon’s nationwide cellular network, though other networks can be used depending on coverage at the deployment location. Cellular connectivity means you’ll have no manual reads and no drive-bys.
*Except for the ultrasonic meter which has an integral register.

Retrofit Applications
The Prism register can also be installed on third-party meter bodies that may already be in your system. This works through the use of adapter rings, which allow the Prism to be securely attached to the top of the meter, where it can track the rotating magnet. This turns a legacy mechanical meter into a cellular smart meter for reliable daily AMI reads.
Compatibility
The Prism register can be installed on selected meters from a wide range of third-party meters. Contact Metron for details of compatibility.
Prism R
For meters which have a three-wire signal output, the Prism R provides cellular connectivity and 1-minute data capture, able to turn a wide range of third party devices into true smart meters.
Frequently Asked Questions
What is a water meter register?
The register is the component of a water meter that records water usage, usually in units of gallons, cubic feet or cubic meters. Historically, registers were mechanical, requiring manual reading. Nowadays, most registers on the market are electronic. Electronic registers may offer remote reading over wireless communications systems such as the commercial cellular networks.
Is Metron’s Prism register electronic?
Yes. In most cases, the Prism register captures water flow through sensing a rotating magnet. These rotations are interpreted as gallons of water, which are recorded every minute. The Prism register uploads 24 hours’ worth of water consumption data every night via a short transmission to the nearest Verizon or AT&T cell tower.
Can the Prism register be read manually?
Yes. The current water usage amount is shown on the LCD display on the register.
Is the Prism register weather-proof?
Yes. The register is fully potted, which prevents water ingress. It’s rated at IP-68: fully submersible.
How long does the internal battery last?
The register is warranted to operate for 10 years, but the battery life is expected to be mich longer than that if operating conditions are normal.
Can the internal battery be replaced?
No.
Does the cellular register represent a health risk from radiation?
No. Metron’s Prism register transmits to the nearest cell tower for just a few seconds, once every 24 hours. The rest of the time, the transmitter is switched off. When transmitting, the radiation power is similar to that of a cellphone.
Can the Prism register be connected to a meter that has a standard 3-wire output?
The Prism R register is designed to connect via a cable to a meter with a 3-wire output.
Can the Prism register be attached to meter bodies from other vendors?
In some cases, yes. Metron offers adapter components which securely attach the Prism register to certain families of meters from other vendors.
