DAE MJ-75n NTEP NSF61 Lead Free Potable Water Meter - Reliable

In this review the DAE MJ-75n is presented as a straightforward, commercial-grade inline water meter aimed at property managers, contractors and facilities teams who need accurate potable water measurement with remote reading options. The bottom line: it is a horizontal inline meter with NTEP approval and NSF61/372 certification, built for reliable accuracy and simple integration with remote read systems. The review focuses on its installation orientation, certified materials, calibration traceability and the options for pulse, AMR and cloud metering so readers can quickly decide if it meets their metering and billing needs.

Key Features

• Horizontal inline mount: Designed to be installed with the dial facing upwards for easy reading and service access.
• NTEP accuracy: National NTEP approval and repeatability testing ensure the meter meets recognized accuracy standards for custody transfer and billing.
• NSF61 and NSF372 certified: Materials comply with ANSI/NSF 61 for drinking water safety and ANSI/NSF 372 for lead free plumbing.
• Pulse output and remote options: Built-in pulse output works with electronic counters and AMR modules for automated reading and billing.
• Cloud metering compatibility: Compatible with the DAE CC2030 Gateway to collect data and deliver alerts and reports to a phone or PC without complex IT work.
• Factory calibration available: Calibration certificates can be provided for projects that require traceable accuracy documentation.

Who It's For

The MJ-75n suits building owners, multiunit landlords and municipal installers who need a reliable, lead free potable water meter for horizontal inline installations and who value certified accuracy for billing or regulatory compliance. It is especially useful when remote read capability or cloud monitoring is desired, since it supports pulse outputs, AMR modules and a cloud gateway.

Those who should look elsewhere include buyers who need a meter for pit installations or a meter that can be installed in any orientation; for vertical installations or outdoor pit use, the DAE PD-75 or MJ-75c variants are the recommended options. Also, if minimum flow requirements under 0.25 GPM are common in your system, confirm suitability before purchase.

Pros & Cons

Pros

• Certified to NTEP and NSF standards, offering confidence for billing and potable water safety.
• Multiple remote reading options from a simple pulse counter to AMR and cloud gateway make it versatile for property metering.
• Factory calibration certificates available provide traceable verification for specification-driven projects.
• Built solidly with customers praising its build quality and value for money in field use.

Cons

• Intended for horizontal inline mounting only, so it is not suitable for every installation orientation.
• Not designed for pit application or certain outdoor conditions without choosing the dedicated outdoor variants.
