DAE MJ-75z 3/4ft Encoded Water Meter with RS485 Communication - Remote

In this review the DAE MJ-75z is presented as a practical, encoded 3/4' water meter aimed at property managers, utilities and installers who need reliable remote readings. The bottom line: the MJ-75z combines a mechanical 3/4' meter with an integrated AMR130 reading device and RS485 output so readings seen on a phone or PC match the register on the meter. Its strength is straightforward remote integration with the DAE CC2030 gateway or wireless converters for retrofit situations, making it useful where accurate, remotely accessible consumption data and simple installation matter most.

Key Features

• Integrated encoding: The meter includes an AMR130 reading device so the mechanical register and digital output remain synchronized for accurate remote reads.
• RS485 communication: Provides a standard wired interface for direct connection to gateways like the CC2030 for cloud metering and billing.
• Cloud and local read options: One CC2030 gateway can read up to 20 encoded meters and generate billing reports viewable on a phone or PC.
• Outdoor and pit suitability: IP68 rating and horizontal inline installation with dial facing up make it appropriate for outdoor installations and pit applications.
• Retrofit friendly: 3/4' NPT couplings simplify replacement installs and the option to add WSC500A RF converters avoids pulling long cables in existing buildings.
• Industry compliance: Accuracy and limits conform to AWWA C708 and ISO 4064 for clean city water, supporting billing-grade use.

Who It's For

The MJ-75z is best for site managers, small utilities and commercial landlords who need a rugged, encoded 3/4' meter that ties into remote monitoring systems without complex IT work. It is especially useful when a single CC2030 gateway will serve multiple meters and generate billing reports from a phone or PC.

Those who need a vertically installable meter in tight spaces should consider DAE's U-75 instead, since the MJ-75z is designed for horizontal inline mounting with the dial facing upward. Also, this meter is intended for clean city water use and not for aggressive or heavily particulate fluids.

Pros & Cons

Pros

• Good build quality and value for money, with customers noting strong functionality at higher flow rates.
• Accurate digital encoding paired with the mechanical register ensures consistent remote and local readings.
• Flexible remote setup: wired RS485 to CC2030 or wireless conversion with WSC500A for retrofit scenarios.

Cons

• Designed for horizontal inline mounting only, so installers needing versatile orientation should choose a different model.
• Intended for clean city water; application to other fluids or heavily contaminated sources is not specified.
