The following sections detail each product to help you compare features, installation flexibility, and potential limitations. Each entry notes who the product is best for and why it was selected for a pulse-output setup.
DAE AS320U-150P 1-1/2″ Pulse Meter
The DAE AS320U-150P uses a horizontal inline mount with the dial facing upwards, and it conforms to AWWA and ISO 4064 standards. This model is ideal for larger residential or light commercial applications that require a 1-1/2″ connection and pulse output integration. It supports cloud metering via the CC2030 Gateway, enabling real-time data access from a PC, cell phone, or smart gateway. Best for property managers or facilities that want remote monitoring and alerting for abnormal usage.
Best for: mid-to-large flow applications where remote monitoring matters and an easy cloud bridge is needed. Choose this if you plan to link with CC2030 for cloud analytics and tenant billing.
Caution: Installation is not suitable for pit applications; ensure proper in-line placement and access for reading pulses. Also, check that your water system can support the 1-1/2″ size in your footprint.
DAE AS200U-75P 3/4″ Pulse Meter
The AS200U-75P is designed for compact spaces with 3/4″ NPT couplings and pulse output. It supports versatile mounting (horizontal inline, or VM-75P in any orientation) and is compatible with cloud metering through CC2030 Gateway. This meter is well-suited for small commercial spaces, single-tenant buildings, or residential units where space is limited but pulse data is required for central monitoring.
Best for: smaller setups needing reliable pulse output without a large footprint. Choose this if you want cloud data access and relatively straightforward installation.
Caution: Not intended for pit installations; ensure the chosen mounting position matches the product’s supported orientations for optimal readings.
RESTMO Brass Flow Meter for Outdoor Use
This model features a brass inlet and outlet with durable metal threading, designed for outdoor garden hoses, RV tanks, and lawn irrigation. It provides an LCD display with four modes: Flow, Consumption, Average, and Total. The RESTMO meter is a practical choice when you want a straightforward, easy-to-read meter to monitor water use outdoors and needs pulse-style tracking for remote reporting, if integrated with an agricultural or garden management system.
Best for: outdoor water usage where a robust, easy-to-read meter is preferred and where simple mode-switching helps track consumption over time.
Caution: The model emphasizes outdoor durability but verify compatibility with your internal piping and ensure the pulse output is configured for integration with your monitoring system.
DAE AS250U-100P 1″ Pulse Meter
The AS250U-100P is a 1″ inline meter designed for higher flow scenarios, with multiple installation options (vertical or horizontal, with dial orientation flexibility). It also supports cloud metering via CC2030, allowing centralized access to meter data for tenants or facilities management. It conforms to AWWA C700 and ISO 4064 Class C, making it suitable for city water applications. This meter balances capacity with versatile placement and cloud-read capabilities.
Best for: higher-volume residential or small commercial scenarios where clear pulse data and remote reading improve operations and tenant billing. Choose this if you anticipate larger flow rates or need enhanced placement flexibility.
Caution: Ensure compatibility with your local water standards and the chosen installation orientation to avoid misreads or reduced accuracy at very low flows.
Watflow DN20 3/4″ Pulse Meter
The Watflow DN20 meter uses a 3/4″ NPT connection and reads in gallons, making it a cost-friendly option for standard domestic water monitoring. It is designed for real-world reliability with a clear specification set including maximum and minimum flow rates, and a reasonable accuracy window. This model is best for simple, budget-conscious installations where pulse output is required but the application does not need the higher-end cloud integration found in larger models.
Best for: basic residential use, DIY projects, or small scale deployments where pulse output is needed without extensive cloud features. Choose this if you value straightforward installation and a lower price point.
Caution: While affordable, ensure the unit is installed in a way that maintains visibility of the pulse output and that the measuring range aligns with your expected flow rates to avoid under-reading at very low or very high flows.
Buying Guide
What should I check before buying a pulse-output water meter?
- Pulse Output Compatibility: Confirm the pulse sensor matches your reader or gateway (for cloud or AMR integrations). Some meters specify compatibility with CO-10, AMR130, or CC2030 gateways.
- Connection Size: Choose the right inlet/outlet size for your plumbing—common options include 3/4″ and 1″ NPT. Larger meters like 1-1/2″ serve higher flow needs but require appropriate fittings and space.
- Mounting Flexibility: If space is constrained, prefer meters with multiple orientation options (horizontal, vertical, dial orientation) to fit your installation accurately.
- Standards and Compliance: Look for AWWA C700/ISO 4064 compliance and other certifications that assure measurement accuracy and compatibility with municipal systems.
- Cloud Metering and Alerts: If long-term monitoring or tenancy billing is a goal, verify that cloud metering works with the gateway and whether alert features are included for abnormal usage.
- Outdoor vs Indoor: Outdoor-rated meters are needed for exterior installations exposed to weather, while indoor meters may be used in suites or basements but require protection from moisture.
- Accuracy and Operating Range: Review stated accuracy and flow-rate ranges (e.g., ±1.5% at normal flows, higher variation at low flows) to ensure readings match your usage patterns.
How to choose among these options?
- Best for cloud-enabled monitoring: AS320U-150P or AS250U-100P due to explicit CC2030 gateway compatibility and flexible mounting.
- Best for small spaces: AS200U-75P offers compact size with robust mounting options.
- Best for outdoor irrigation or garden setups: RESTMO Flow Meter provides a brass body with an LCD and multiple modes for straightforward outdoor tracking.
- Best budget-friendly domestic option: Watflow DN20 balances cost with a reliable pulse output for standard home use.
What about installation considerations?
- Ensure straight running pipes around the meter to minimize turbulence that can affect readings.
- Place the meter where access to the pulse output connections is easy for maintenance and wiring.
- For cloud-enabled meters, plan network connectivity and gateway placement to ensure reliable data transmission to the cloud.
Quick comparison by scenario
- Tenant billing in a multi-unit building: AS320U-150P or AS250U-100P with CC2030 gateway.

Frequently Asked Questions
- Do pulse-output water meters work with smart home hubs? Yes, when paired with a compatible gateway or AMR module that forwards pulses to a cloud service or local reader.
- Can these meters be installed outdoors? Some models are designed for outdoor use or have outdoor-compatible ratings; verify the product notes for each model.
- What does “pulse output” mean in practice? It refers to a signal tied to discrete flow events, enabling remote counting of water usage when connected to a reader or gateway.
- Are these meters compliant with U.S. standards? Several listed models cite AWWA and ISO 4064 classifications, indicating standard-compliant measurement.
- Can I switch between vertical and horizontal mounting after installation? Some models support multiple orientations (VM-75P/VM-100P, etc.), but you should confirm specific model capabilities before installation.
- Is there any risk in using a smaller meter for high-flow buildings? Yes, a meter size mismatch can under-report usage at high flow; choose a meter sized for your expected peak flow.
