DAE MJ-75f NTEP NSF61 3/4ft Potable Water Meter - Durable Inline Meter

In this review the DAE MJ-75f is presented as a straightforward, utility-focused water meter for building managers, landlords and industrial users who need a reliable inline meter with pulse output. The bottom line: it is best for clean potable water applications where NTEP accuracy and NSF61/372 material safety matter most. The reviewer found the meter well built, factory-calibrated options useful, and its horizontal inline design with dial facing up makes it an easy replacement for existing 3/4' NPT runs.

Key Features

• Horizontal inline mount: Designed to install with the dial facing upwards, making reading and maintenance straightforward for most meter runs.
• NTEP accuracy: National NTEP approval and repeatability testing provide confidence in billing and measurement across jurisdictions that accept NTEP.
• NSF61 and NSF372 certified: Materials meet ANSI/NSF 61 and lead free requirements under NSF372, assuring safe use with potable water.
• Pulse output and remote options: Built to work with pulse counters, CO-10 kits, AMR modules or the CC2030 gateway for cloud metering and remote monitoring.
• Flow range and accuracy: Accurate to +/-1.5% across the normal flow range and suitable for flows from 0.25 GPM up to 20 GPM for typical residential and light commercial use.
• Factory calibration available: Option for calibration certificate from the factory for users who require documented traceability.

Who It's For

The MJ-75f is ideal for landlords, multifamily property managers, and small commercial facilities that need a durable 3/4' NPT inline water meter with proven accuracy and safety certifications. It is particularly useful when remote readout or cloud metering is desired, since it supports pulse output and integrates with DAE remote modules and the CC2030 gateway.

Those who need a meter that can be installed in any orientation, or who require pit-rated or outdoor-specific housings, should consider alternate models in the series. This unit is intended for clean city potable water and is not for pit applications or other special environments.

Pros & Cons

Pros

• Well made with solid build quality noted by customers and reviewers.
• Certified to NTEP and NSF standards which supports legal-for-trade use and material safety.
• Flexible remote reading options from simple pulse counters to cloud metering via CC2030.

Cons

• Horizontal inline only with dial up limits orientation compared with alternate models that allow any position.
• Not intended for pit applications or harsh outdoor exposures without selecting the outdoor-rated variants.
