Note: All products listed are intended for potable water measurement in residential or light commercial settings. Choose the model whose connection size and readout method match your installation and data needs.
Watflow DN20 Water Meter — 3/4″ NPT, Pulse Output
The Watflow DN20 model uses corrosion-resistant eco-brass alloy for its main water-contact components and comes with 3/4″ NPT couplings for common USA plumbing. It measures in gallons and supports a pulse output option for data integration. Best for homeowners or small properties needing straightforward meter data and compatibility with standard fittings.
Best for: Homeowners and small offices needing easy installation and pulse-ready data capture. Why selected: Strong corrosion resistance and widely compatible 3/4″ connections. Limitation: Pulse output availability may vary by configuration.
MEASUREMAN 3/4″ Non-Pulsed Gallon Meter
The MEASUREMAN meter features a single-jet mechanism for minimal maintenance and easy-to-read dial readings. The blue brass body contributes to durability, making it well-suited for cold water lines in homes or RV systems. Best for: Users seeking simple, reliable, non-pulsed measurement with clear readings. Limitation: Does not provide pulse data for remote monitoring.
H2 Flow Controls FV-C FlowMeter
The FV-C model combines a flow meter with a check valve, providing a compact solution for installations where backflow prevention is important. It offers a clear scale in GPM or optional LPM and supports flexible mounting orientations (horizontal, vertical, or inverted). Best for: Pools, spas, or plant systems where backflow prevention and versatile mounting are priorities. Limitation: Reading accuracy can be influenced by installation angle and velocity points.
Watflow DN15 Water Meter — 1/2″ NPT
This 1/2″ NPT model provides a compact option for residential plumbing with ISO4064-style accuracy and a PVC-compatible, BPA-free construction. It’s designed for horizontal installation and is appropriate for light domestic water metering. Best for: Small apartments or tight spaces requiring a low-profile meter. Limitation: Lower maximum flow rate may limit use in higher-demand systems.
DAE AS200U-75P — Pulse-Output Water Meter
The DAE AS200U-75P focuses on pulse-output data with 3/4″ NPT couplings and gallon measurement. It supports vertical or horizontal installation with upward-facing dial options, and cloud metering compatibility via specific gateway modules. Best for: Infrastructures needing remote monitoring and data collection. Limitation: Requires additional hardware for cloud connectivity, not a standalone solution.
Buying Guide
Key considerations when choosing a single-use water flow meter:
- Connection size and type: Match 1/2″ or 3/4″ NPT to your plumbing. Consider adapters if needed.
- Measurement unit: Gallons is common in the US; ensure the meter’s totalizer matches your preferred unit.
- Output options: Pulse output supports data logging and integration; non-pulsed meters are simpler but harder to monitor remotely.
- Installation layout: Horizontal, vertical, or mixed orientations can impact readability and accuracy; check mounting allowances for each model.
- Durability: Look for corrosion-resistant housings (eco-brass or blue brass) for longer life in potable water lines.
- Maintenance: Single-jet meters typically need less maintenance than more complex mechanical systems.
- Remote monitoring: If real-time data is essential, prioritize meters with pulse output and cloud-ready options.
FAQ
- What is a single-use flow meter?
A device that measures the flow rate of water in a single installation, typically without requiring complex integration or multiple simultaneous channels. - Do these meters support remote data collection?
Some models offer pulse outputs and cloud-enabled features, while others provide only local readouts. - Which meter is best for small apartments?
The Watflow DN15 or MEASUREMAN 3/4″ non-pulsed models are compact and straightforward for limited-space installations. - Can I install these meters horizontally and vertically?
Many models support multiple orientations, but always verify the manufacturer’s mounting guidelines for accuracy. - Is pulsating output more accurate than a dial readout?
Pulse outputs enable data logging and integration with monitoring systems, which improves long-term accuracy for usage tracking. - Are these meters suitable for outdoor use?
Some models are designed for indoor plumbing; refer to each product’s installation notes for outdoor suitability.
