DAE MJn-200R 2 in Hot Water Meter, Pulse Output + Couplings - Reliable

In this review the DAE MJn-200R 2 in Hot Water Meter is judged on practicality and long-term use for property managers and light industrial sites. The bottom line: this meter is for anyone who needs a robust, horizontal inline water meter with accurate pulse output and easy integration into remote reading systems. The reviewer found it particularly useful where landlords require consolidated billing and real-time alerts because it pairs smoothly with DAE remote-reading gateways and counters, delivering dependable readings with +/-1.5% accuracy in normal flow ranges.

Key Features

• Horizontal Inline Design: Mounts with the dial facing up for easy reading and service access without special orientation changes.
• Pulse Output: Provides a simple electronic pulse signal for integration with counters, AMR modules, or data gateways for remote reading.
• Cloud Metering Ready: Works with the DAE CC2030 Gateway to send consolidated data to a cloud server for real-time viewing and monthly billing reports.
• Compatibility with Remote Readers: Ready for CO-10 electronic pulse counter or AMR130 and AMR systems for single or multi-meter setups, offering flexible remote read options.
• Certified Standards: Conforms to AWWA C700 and ISO 4064 Class C and meets AWWA C708 accuracy expectations for clean city water.
• Factory Calibration Available: Calibration certificates can be provided for installations that require documented accuracy verification.

Who It's For

This meter is aimed at landlords, property managers, and facilities operators who need accurate water measurement with options for remote reading and cloud-based reporting. It is a practical choice for buildings where water flows horizontally and the dial must be visible and serviceable from above.

Those who need vertical installation with upward flow should look at the DAE vertical model instead, and users requiring specialty water types or non-city water applications should verify compatibility before purchase.

Pros & Cons

Pros

• Solid build quality and reliable readings at higher flow rates, with users noting stable performance above 50 GPM.
• Easy integration into remote reading ecosystems via pulse output, CO-10 counters, or AMR modules for centralized billing.
• Cloud-capable when paired with the proper DAE gateway, providing alerts and usage history without complex IT setup.

Cons

• Designed for horizontal inline mounting only; a separate vertical model is required for upward-flow installs.
• Accessories like CO-10 counters, AMR modules, or the CC2030 gateway are sold separately, adding to total system cost.
