Whitepaper: Independent Accuracy Verification

SimpleSUB’s clamp-on submeters deliver ±5% accuracy across copper and PEX pipes, with results proven in lab and real-world studies.

‍Why Download This Whitepaper?

Property managers, owners, and engineers often ask: Can clamp-on submeters really be trusted for tenant billing? This independent study provides the answer. With detailed lab data and a real-world field test, this report removes the uncertainty and shows how SimpleSUB performs in the conditions that matter most.

Inside, you’ll get:

• Independent lab results comparing SimpleSUB i1 and x1 to a 0.25% magnetic flow standard. The whitepaper provides side-by-side results that demonstrate consistent accuracy across flow rates. By using a trusted reference standard, this study verifies performance under controlled conditions and builds confidence for billing use.‍
• Performance across all pipe types and diameters (½″, ¾″, 1″ in copper and PEX). Unlike many solutions that only perform well in specific scenarios, SimpleSUB devices were tested across the full range of common residential pipe sizes and materials. Results show that the accuracy specification holds across all cases, even when manufacturer variations are introduced.‍
• Real-world validation from a multi-month field test against a Sensus utility meter. Numbers on paper are one thing—but real-world performance is what matters most. The field validation proves that SimpleSUB submeters stay aligned with utility-grade meters over time, even under industrial use and changing conditions.‍
• Best practices for installation and ongoing reliability. Proper installation is key to long-term success. This section of the whitepaper outlines the most common mistakes to avoid and shares guidelines to maximize accuracy from day one.‍
• Key takeaways on why clamp-on ultrasonic submeters are a cost-effective alternative to inline meters. Traditional inline meters often require cutting pipes, shutting off water, and hiring plumbers. This whitepaper explains how SimpleSUB’s clamp-on approach avoids these disruptions—saving both time and money while still delivering verified accuracy.

Who Should Read It?

This whitepaper was created for decision-makers who want to make informed choices about water submetering solutions, such as:

• Property managers will learn how to reduce disputes with tenants by billing based on reliable data.
• Owners will see how submetering can increase transparency and protect margins without large upfront plumbing costs.
• Engineers and consultants will find verified technical results that support design decisions and compliance requirements.
• Multifamily developers will discover a retrofit-friendly option that avoids costly pipe modifications and minimizes disruption to residents.

Highlights from the Whitepaper

Independent testing confirmed SimpleSUB accuracy within ±5% across all pipe sizes and materials. That means whether you’re installing on copper or PEX, ½″ or 1″, you can expect consistent results.

Installation is another major advantage. SimpleSUB devices mount externally on the pipe, meaning no water shutoff or cutting is required. This not only saves installation costs but also avoids tenant scheduling headaches.

In the field, SimpleSUB submeters proved their reliability by tracking closely with utility-grade Sensus meters over multiple months. Even with varying industrial water usage patterns, results consistently fell within the published accuracy specification.

And with long-life batteries, built-in diagnostics, and no moving parts to wear down, SimpleSUB submeters are built to operate reliably for years with minimal maintenance.
