Puritech 0.5-5 GPM Flow Meter – Precise Measurement for Water Systems

The Puritech 0.5-5 GPM flow meter provides accurate and reliable measurement of water flow in treatment systems. Because it covers a flow range of 0.5 to 5 gallons per minute (≈1.8–18 LPM), it suits both low- and moderate-flow systems. Moreover, its compact construction and ½″ port make it easy to install in a wide variety of applications. As a result, you gain actionable data on flow rates for system monitoring and optimization.

Key Features

• Flow Range: 0.5–5 GPM (1.8–18 LPM) per the Puritech spec sheet.
• Port Size: ½″ inlet/outlet — compatible with common water-treatment plumbing.
• Material: A Combination of plastic and metal for a good balance of durability and affordability.
• Operating Pressure: Rated for up to ≤ 1 MPa, sufficient for most residential and commercial water-treatment systems.
• Temperature Range: 0-65 °C, which covers typical use in water systems.
• Accuracy: ±4%, delivering reliable flow readings under normal conditions.
• Installation Orientation: Must be installed vertically, with liquid flowing from bottom to top.
• Suitable Medium: Water (or similar liquid systems).

Benefits

1. Flow Monitoring: Allows precise tracking of water flow through RO, filter, or treatment systems, helping you spot issues or inefficiencies.
2. System Optimization: By knowing the exact flow rate, you can size pumps correctly, maximize media life, and reduce wasted water.
3. Durable Build: The robust material ensures long-lasting performance even under regular use.
4. Easy Integration: Standard ½″ port and compact body mean it fits easily into existing plumbing without major modifications.
5. Accurate Readings: With 4% accuracy, it’s precise enough for most water-treatment control and monitoring applications.

Ideal Applications

• Reverse osmosis (RO) system feed-line monitoring
• Filter media systems to measure service flow
• Water softeners or pre-treatment systems
• Plumbed-in water-treatment loops where flow measurement is needed
