Watflow DN20 Water Meter with AWWA 708 Certification
The Watflow DN20 meter uses eco-brass main cases and a three-component design for corrosion resistance. It features 3/4″ NPT inlet and outlet and measures in gallons, aligning with common U.S. residential plumbing. Accuracy is described as ±1.5% in normal flow and ±3% at low flow, with a maximum of 20 GPM and a minimum of 0.25 GPM. Best for homeowners needing a dependable municipal-grade reading in a standard 3/4″ installation. Caution: verify installation orientation to ensure correct flow direction, as the meter specifies horizontal installation for this model.
Who this is best for: Homeowners, renters, or property managers seeking a durable, standard-size meter with straightforward gallon readings for general water usage tracking.
Watflow DN20 Water Meter with AWWA C712
This Watflow model emphasizes corrosion resistance with eco-brass main cases and 3/4″ NPT couplings. It measures in gallons and aims to fit typical U.S. residential setups. Accuracy mirrors the other Watflow option: ±1.5% in normal flow and ±3% at low flow, with flow ranges up to 20 GPM. Best for installations where C712 certification is a priority and a robust, up-to-date standard matters. Caution: ensure compatibility with existing piping if you have older installations that use different thread standards.
Who this is best for: Users who want an ISO/ANSI-aligned meter with strong corrosion resistance and a straightforward installation in a 3/4″ line.
DAE AS200U-75 Water Meter, 3/4″ NPT
DAE’s AS200U-75 is a horizontal inline meter with upward-facing dial, and it supports vertical installations with related models. It is described as compatible with upgraded cloud metering (AS200U-75P) and AMR options, enabling remote reading via gateways. It adheres to AWWA and ISO 4064 standards and is positioned for multi-building properties seeking cloud-based data. Better for settings where tenants or building managers need real-time usage data and alerting. Limitation: advanced cloud features require additional hardware not included in the base package.
Who this is best for: Property managers or owners who want remote metering capabilities and scalable readings across multiple meters.
Watflow Lead-Free DN20 Meter
This lead-free variant uses BRASS LEAD FREE construction and 1/2″ NPT couplings, with gallon-based readings. It mirrors the standard Watflow design—precise ±1.5% normal flow, ±3% at low flow, high-flow capability up to 20 GPM, and a low 0.25 GPM minimum. Best for spaces prioritizing lead-free materials for drinking water safety and compact 1/2″ connections. Caution: flow scope differs from 3/4″ models; ensure the pipe size matches before purchase.
Who this is best for: Homes requiring lead-free materials and a compact, 1/2″ connection for tight installation spaces.
Watflow ISO4064 Meter with PVC, 3/4″ NPT
This PVC version of a Watflow meter carries ISO4064 certification and uses a 3/4″ NPT connection. It’s designed for garden or home use and emphasizes safe, BPA-free materials with a durable, non-metallic body. It supports horizontal installation and provides straightforward gallon readings with a normal flow max around 10 GPM. Better for outdoor-influenced applications or properties seeking PVC construction for corrosion resistance and ease of handling. Caution: lower maximum flow compared to some metal-bodied options; ensure your water usage patterns fit within the 10 GPM normal flow ceiling.
Who this is best for: Garden-focused homes or properties needing a PVC-bodied meter with simple horizontal installation.
Buying Guide: Key Purchase Considerations
What meter size do I need? For most residential settings, a 3/4″ NPT connection is standard. Confirm your piping and fittings before buying to avoid compatibility issues.
Should I choose lead-free or brass? Lead-free meters are preferred for drinking water safety, especially in homes with potable water lines. Brass models offer durability and cost efficiency in many installations.
What accuracy matters? Most meters list ±1.5% accuracy in normal flow and ±3% at low flow. If your usage has extended low-flow periods (e.g., vacation homes), consider a model with strong low-flow accuracy.
Is a cloud or AMR option worth it? For multi-meter properties, cloud-ready options enable remote monitoring and alerts. These require additional hardware but can simplify tenant billing and leak detection.
Installation orientation and environment? Horizontal installation is common, but some models support vertical setups. Outdoor meters may require weather-rated housings or IP ratings; check product notes for outdoor suitability.
What about certifications? ISO4064 or AWWA certifications indicate adherence to recognized metering standards, which can be important for municipal compatibility and long-term reliability.

Frequently Asked Questions
- What does DN20 mean? It refers to the nominal diameter (20 mm) of the meter’s connection, commonly matched to 3/4″ NPT in U.S. residential plumbing.
- Do these meters measure in gallons or cubic meters? Some models read in gallons while others read in cubic meters; check the product features to confirm the measurement unit.
- Can I install meters vertically? Some models allow vertical installation with specific orientations; always follow the manufacturer’s guidance for proper flow direction.
- Are cloud-based meters worth it? For property management, cloud-readiness can streamline data collection and tenant billing, but it requires additional gateway hardware and setup.
- What certifications should I look for? ISO4064, AWWA, and NTEP/NF readings indicate adherence to established metering standards and safety.
