DAE MJ-100m 1ft NSF61 Non Lead Potable Water Meter - Accurate Inline

Our review of the DAE MJ-100m finds it best suited for property managers and service technicians who need a reliable, certified water meter for clean city water systems; the single biggest reason to buy is its combination of NSF61/372 certification and compatible remote-reading options that simplify tenant billing and monitoring. The meter is a horizontal inline design with the dial facing up, factory calibration available, and a pulse output that works with inexpensive counters or DAE AMR modules, making it practical for multi-unit plumbing where accurate, lead-free measurement and remote data are required.

Key Features

• NSF Certified: ANSI/NSF 61 and 372 certification ensures materials meet potable water safety and lead-free plumbing standards for peace of mind in tenant or residential use.
• Horizontal Inline Mount: Designed for horizontal installation with the dial facing upwards, which simplifies reading and maintenance in common plumbing runs.
• Pulse Output: Built-in pulse output enables easy integration with electronic counters or AMR modules for remote reading and automated billing.
• Cloud Metering Ready: Compatible with the CC2030 Gateway to deliver real-time and historical usage to a cloud portal without complex IT setup.
• Calibrated Accuracy: Factory calibration certificates are available and the meter conforms to ISO 4064 and AWWA standards for dependable measurement.
• Good Flow Range: Handles a wide usable flow range with a safe maximum of 11.356 cu m/h and recommended continuous flow up to 5.678 cu m/h, suitable for many residential and light-commercial applications.

Who It's For

The DAE MJ-100m is aimed at landlords, building engineers, and plumbers who need a certified, inline potable water meter with remote-read capability and pulse output for integration into billing systems. It is particularly useful in multi-tenant or metered rental situations where monthly usage tracking and alerts for abnormal consumption are valuable.

Those needing vertical or pit installations, outdoor frost-resistant models, or a meter that can be oriented in any position should consider alternative DAE models such as the PD-100 or MJ-100c, as this unit is specified for horizontal inline mounting with the dial facing upwards and not recommended for pit use.

Pros & Cons

Pros

• NSF61/372 certification ensures safe, lead-free materials for potable water installations.
• Pulse output and compatibility with CO-10, AMR130 and CC2030 gateway enable flexible remote-reading setups.
• Factory calibration and conformity to AWWA/ISO standards deliver reliable measurement and documentation.
• Wide usable flow range covers typical residential and light-commercial demands.

Cons

• Designed specifically for horizontal inline mounting with the dial up, so it is not versatile for vertical or pit installations.
• Remote-reading accessories such as CO-10 or AMR modules are sold separately, adding to total system cost.
