DAE MJ-100n 1 in NTEP NSF61 Non Lead Water Meter - Reliable Commercial

In this review of the DAE MJ-100n 1 in NTEP NSF61 Non Lead Potable Water Meter the bottom line is simple: this is a workmanlike, accurate meter for commercial or multi-tenant city water applications where NTEP approval and NSF61 material safety matter. The reviewer found it best for in-line horizontal installations with the dial facing up, delivering consistent readings across the stated flow range and providing straightforward compatibility with remote reading options. If you need a certified, lead-free meter with pulse output and optional cloud connectivity, this meter makes a clear case.

Key Features

• NTEP approved accuracy: National NTEP testing and repeatability assures compliance for billing and regulatory use across states that accept NTEP or CTEP.
• NSF61 and NSF372 certified: Certified materials and lead-free compliance reduce concerns about potable water safety and regulatory acceptance.
• Horizontal inline installation: Designed for horizontal mount with dial facing up, simplifying installation in typical mechanical rooms or meter cabinets.
• Pulse output and remote readiness: Built-in pulse output works with CO-10, AMR130, or AMR systems for remote reading and data capture.
• Cloud metering option: Compatible with the CC2030 Gateway to send real-time usage and alerts to a cloud server without complex IT setup.
• Calibration certificates available: Factory calibration documents are offered for projects that require traceable accuracy records.

Who It's For

This meter is aimed at property managers, plumbers, and facility engineers who need a certified potable water meter for city-supplied water and want reliable billing-level accuracy. It is especially useful where NTEP approval and NSF61 material compliance are required for installation or code acceptance.

Those who need vertical installation flexibility, pit installation, or an outdoor-rated unit should consider alternative models in the DAE line such as the PD-100 or MJ-100c, which are specified for different mounting orientations and environmental conditions.

Pros & Cons

Pros

• Durable build and good value, matching customer impressions of solid quality for price.
• Accurate and repeatable readings within AWWA limits, suitable for billing and diagnostics.
• Ready for remote reading and cloud integration, enabling alarms and remote billing reports.

Cons

• Limited to horizontal inline mounting with the dial facing up, so it is not suitable where vertical or pit installation is required.
• Outdoor installations require a different model; this unit is not specified for pit use.
