GRYVOZE Waterproof 1 Inch Flow Meter
Best for landlords handling sites with water exposure or metal equipment nearby. This meter is fully waterproof and designed to withstand tough wet conditions, ensuring accurate readings in basements, outdoor taps, or pump rooms. EMI protection reduces risk of incorrect data from nearby motors or pumps, a common issue in older buildings. It offers versatile unit options, allowing readings in gallons, quarts, pints, or liters, which can simplify tenant billing or water budgeting. Flow range supports typical residential and light commercial usage. Choose this if your installation environment has moisture, splashes, or electrical interference. A potential limitation is that it functions as a flow meter rather than a stand-alone building sub-meter; pairing with a separate data logger or panel may be necessary for full tenant billing.
Digital Electric Sub Meters For Landlords
Best for multi-tenant electrical billing and shared utility monitoring in small commercial or residential setups. This model supports 120/240V CL200 single-phase power and is designed for simple installation in standard 2S form bases, making it suitable for rental units, RV pads, or workshops. It clearly displays kWh usage, enabling straightforward billing and energy audits. It also supports sub-metering across tenants and can integrate with basic data collection for quick insights. Better for landlords who want precise tenant-level electricity data and straightforward wiring, but note that it’s an electric meter, not a water meter, so use in buildings where electricity billing is the goal.
DAE MJ-75f NTEP NSF61 Water Meter
Best for landlords needing accurate potable water metering with regulatory alignment. The MJ-75f is NTEP and NSF61 certified for water safety and measurement accuracy, with a 3/4″ NPT coupling. It supports horizontal inline mounting with the dial facing upwards, and it mentions compatibility notes for vertical installations via alternative models. It enables cloud metering through the CC2030 gateway, which supports remote reading across multiple meters. Choose this if you require regulatory-grade accuracy and optional remote data access for tenant billing and leak detection. A caveat is that specific installation orientation guidance should be followed to ensure optimal measurement.
DAE V-75P Vertical Water Meter
Best for properties requiring vertical installation with water flow direction upwards. The V-75P is designed for vertical mounting with a dial facing upwards and supports cloud metering via the CC2030 Gateway. It’s suitable for rental homes and small buildings that want remote access to usage data and alerting for abnormal usage. It also notes alternative models for different flow directions and outdoor ratings. A limitation is that some configurations rely on additional gateway hardware for cloud connectivity, which can increase setup complexity and initial cost.
DAE VM-100P 1” Positive Displacement Meter
Best for landlords who need versatile mounting and cloud-enabled sub-metering with high readability. The VM-100P is a 1” positive displacement meter that can be mounted in any position and includes an internal non-return valve. It supports cloud metering with the CC2030 gateway, allowing real-time data and monthly usage reports for tenants. It’s ideal for properties with dynamic water usage patterns and where proactive leak detection is beneficial. A limitation is potential audible clicking in some installations, which can be mitigated by proper mounting.
DAE AS-75m Water Meter
Best for modern rental properties needing flexible installation and cloud access. The AS-75m supports horizontal inline mounting with a dial facing upwards and offers cloud metering via the CC2030 gateway for remote data. It’s suitable for landlords who want transparent tenant-billing data and alerts for unusual usage. It can be upgraded to AS-75mP for enhanced remote features. A consideration is that cloud integration adds setup steps and possible ongoing data management requirements.
DAE PVM-75 Positive Displacement
Best for straightforward, reliable water metering with remote reading. The PVM-75 is a plastic, positive displacement meter suitable for various orientations and includes an internal non-return valve. It pairs with cloud metering to help landlords monitor usage remotely and send alerts for abnormal patterns. It’s a practical choice for smaller properties seeking simple, scalable metering with digital data. A note: it may produce a clicking sound in some installations, which can be reduced by proper mounting or bracket support.
DAE MJ-100R 1″ Non Lead Hot Water Meter
Best for higher-usage properties or buildings planning cloud access for extensive data. The MJ-100R is a 1″ hot water meter with pulse output and cloud metering capability via CC2030. It supports a more comprehensive tenant billing approach and real-time monitoring for larger rental portfolios. It’s suitable for landlords who want robust data access and automated reporting. A potential limitation is the need for compatible cloud gateway devices and integration steps, which may require professional setup.
Buying Guide: Key Considerations For Water Sub Meters
- What type of water meter do I need? Horizontal vs. vertical, inline vs. displacement, and whether you require pulse output for remote readings.
- Do I need cloud metering? If you want remote access, real-time usage data, and alerts, choose meters with CC2030 gateway compatibility.
- What installation orientation is allowed? Some meters support any position, others have preferred orientations; confirm for each property’s plumbing layout.
- What is the scope of sub-metering? For multiple tenants, consider sub-panel or AMR/AMI integration to scale billing and data collection.
- Are there regulatory or safety considerations? NSF/ANSI certifications help ensure compliance with water safety standards.
- What is your budget and maintenance plan? Higher-end cloud-enabled meters offer convenience but require ongoing data management; budget accordingly.
Frequently Asked Questions
- What is a water sub meter and why use one? A water sub meter tracks usage for a specific unit or area, enabling fair tenant billing and leak detection beyond the building’s main meter.
- Can cloud metering be retrofitted to existing meters? Yes, many models support optional cloud gateways that collect data from multiple meters and upload to a cloud service.
- Are all meters suitable for outdoor use? Not all; check IP ratings and model guidance for outdoor or damp environments before installing outside.
- Is EMI protection important for water meters? EMI protection helps prevent incorrect readings caused by nearby motors or pumps, especially in dense mechanical rooms.
- What installation orientation should I choose? If space is constrained, vertical mounting with upward flow can work; otherwise horizontal inline are common for easy plumbing.
- Do these meters require professional installation? Some models are DIY-friendly, but cloud integration and remote reading setups often benefit from professional installation.
