Overview
Ultrasonic indoor water meter with a built-in Transceiver.
The ultrasonic NextMeter Indoor integrates sophisticated solid-state measuring technology with the NextCentury wireless platform, making it the first solid-state meter purpose-built for the submetering industry.
The NextMeter combines cutting-edge ultrasonic technology with the industry-leading AMR solution, all in a simple and easy-to-use meter designed for effortless deployment. NextMeter ultrasonic technology reliably detects even the smallest amount of flow and extends this level of accuracy across all flow rates.
With the best metering and wireless components combined into a single device, the NextMeter greatly reduces both installation and programming time.

Installation
Install the meter
Attach meter couplings
Secure couplings set to the water line and place new gaskets in each end.
Ensure correct spacing
The water line should be parallel and should have a spacing of 7.5"or 190.5 mm.
Caution
Spacing should allow for meter without pushing, pulling, or kinking the line.
Secure the NextMeter
Place the NextMeter and tighten both ends to a max torque of 11 ft-lb using a flat jaw or monkey-style wrench.
Caution
Do NOT overtighten meter couplings as this may result in the gaskets not forming a proper seal
Pressurize the water line and check for any leaks at both connection points
Verify NextMeter communication
Open the NextMeter register lid. The Meters’s RF LED will blink green when it is able to communicate with its Gateway.
Note
The NextMeter must be programmed in the NextCentury Cloud and its Gateway must be online in order for it to begin communicating with its Gateway.

The NextMeter Indoor offers two versatile output options. It utilizes built-in NextCentury Connect™ wireless technology for seamless communication with our cloud-based data management software, ensuring real-time data transmission. Additionally, there's a wired pulse output available for users who prefer or require a wired connection. These options provide flexibility to suit your specific monitoring needs.
The wired output uses the Meter Out Cable, a 6 ft cable with three 22-gauge wires. See the Meter Out Cable Quick Start Guide.
The battery used, a field-replaceable CR18505 lithium battery, has a typical longevity of 10+ years.
For information on purchasing replacement batteries for the NextMeter Indoor, please contact your product supplier or get in touch with our dedicated support team.
The NextMeter Indoor is engineered to perform beyond standard requirements and can endure pressures far above standard water supply specifications. It has been tested to endure over 100,000 pressure cycles.
Yes, the NextMeter Indoor undergoes NSF testing to ensure quality and safety in compliance with NSF standards.
The NextMeter Indoor uses gallons as the default unit of measurement but also supports liters. To switch to liters or request a different unit of measure, please contact our Support Team for assistance.
The NextMeter Indoor is designed to intelligently measure and subtract reverses in water flow (sometimes called “backflow”). If the total amount of reverse flow exceeds the total of normal flow, the meter will display zero (not a negative number). In the event that a meter reaches zero due to net-negative usage, the read will begin incrementing forward as soon as normal flow is detected.
This feature has been thoughtfully designed as part of our commitment to deliver accurate metering to enable correct billing. Without the ability to account for reverse flow, the same water might be metered multiple times (once upon its initial pass through the meter, and again on any subsequent passes after the reverse flow has been resolved), which wouldn’t allow for fair billing. Accurately accounting for reverse flow maintains fair and accurate billing for utility providers, billing companies, and residents alike.
Note
Even though the NextMeter Indoor can measure reverse flow, proper installation requires the meter to be installed with the arrow on the device pointing in the direction of the normal/expected flow of water.
