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
- Flow Monitoring: Allows precise tracking of water flow through RO, filter, or treatment systems, helping you spot issues or inefficiencies.
- System Optimization: By knowing the exact flow rate, you can size pumps correctly, maximize media life, and reduce wasted water.
- Durable Build: The robust material ensures long-lasting performance even under regular use.
- Easy Integration: Standard ½″ port and compact body mean it fits easily into existing plumbing without major modifications.
- 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
