- High-capacity flow tracking suited for commercial irrigation and wells.
- Rugged multi-jet design minimizes wear and maintains accuracy over time.
- Includes complete 2″ NPT couplings for straightforward installation.
Best for: Commercial sites or large landscapes needing robust, long-term metering. Caution: Larger size may require professional plumbing work and space considerations.
Buying Guide
What should you consider when choosing a flow meter for irrigation?
Flow range and pipe size determine compatibility with your system. Choose a model that fits your main line or zone line (1″, 3/4″, or 2″).
- Smart controller compatibility: If you want alerts, remote control, and zone-level reporting, pick meters designed for your controller brand.
- Display versus remote monitoring: Some meters provide local displays, others connect to apps or cloud dashboards. Decide which fits your workflow.
- Installation and retrofits: Some meters slip into existing lines with unions or NPT fittings; others may require professional wiring or piping changes.
- Leak detection and alerts: Look for high- and low-flow alerts to catch leaks, clogs, or stuck valves early.
- Durability and environment: For commercial sites, rugged designs and corrosion-resistant bodies improve longevity in outdoor conditions.
How to plan a meter upgrade or retrofit?
Map your irrigation zones and identify line sizes. Prioritize meters that integrate with your existing controllers to avoid complex rewiring. If you manage a large property, high-capacity meters with SCADA or BMS integrations offer scalable monitoring.
What about installation and maintenance?
Many meters include unions or quick-connect fittings for easier installation. Expect periodic recalibration or sensor checks in high-flow systems, and keep spare seals handy for long outdoor use.
Comparison at a glance
- Best for Hydrawise ecosystems: Hunter HC100FLOW or HC075FLOW provide native integration and alerts.
- Best for flexible controller compatibility: EveryDrop Flowmeters offer broad compatibility with multiple smart controllers.
- Best for wired-display users: EveryDrop WM-1004 shows flow on-site and works with several popular controllers.
- Best for commercial-scale needs: PRM 2″ Brass Meter handles high flows and rough-duty environments.
Frequently asked questions
- Do flow meters work with all sprinkler controllers? Most meters are controller-compatible, but confirm supported integrations and communication protocols for your setup.
- Can a flow meter help reduce water bills? Yes, by detecting leaks, overwatering, and inefficient zones, enabling precise adjustments.
- Is a display meter better than a wireless one? Displays provide on-site visibility; wireless meters offer remote data via apps or dashboards.
- What size meter do I need? Match the meter to your main line or valve size (1″, 3/4″, 2″). Larger properties may require commercial-grade models.
- Are there maintenance needs? Most meters require occasional inspection; ensure seals and fittings remain leak-free in outdoor conditions.
- Can I install a meter myself? Many meters are designed for DIY installation with unions or standard fittings; larger commercial models may require a professional.
