1-1/2" MPT FLOW METER 3.5 - 55GPM

Product Overview

Undetected leaks and inaccurate flow data can lead to catastrophic system shutdowns or localized crop loss during the peak of the irrigation season. When a flow meter fails or is missing entirely, your crews lose the ability to verify that water is actually reaching the root zone, potentially resulting in failed inspections or costly turf damage. With summer heat approaching and supply chains often experiencing delays on specialized fluid control components, securing your monitoring equipment now prevents mid-season project bottlenecks. Having the right Netafim meter on hand ensures your projects remain on schedule and your clients continue to see the results they expect.

The Netafim USA 1-1/2 inch MPT Propeller Flow Meter offers a significant technical advantage over lower grade digital sensors that are prone to interference. This mechanical propeller design provides reliable, real-time data without the need for complex external power sources in basic configurations. By choosing a professional grade meter, you reduce long term maintenance costs and eliminate the guesswork associated with manual flow calculations. Staying well stocked with these units gives your firm a competitive edge by allowing you to deliver precise water management solutions that lower water waste and operational expenses for your customers.

Key Features

• Heavy duty construction resists UV degradation and chemical exposure in harsh field conditions.
• Low friction propeller design ensures accuracy even at the lower end of the 3.5 GPM flow range.
• Male Pipe Threading allows for direct integration into standard PVC or poly manifolds.
• Mechanical register provides immediate visual confirmation of flow for easier field troubleshooting.
• Internal components are designed for easy cleaning and field serviceability to extend service life.
• Optimized hydraulic design minimizes pressure loss across the meter to maintain system efficiency.

Common Applications

• Commercial landscape irrigation
• Agricultural and crop irrigation
• Greenhouse and nursery operations
• Municipal parks and public spaces
• Chemical and fertigation delivery
• Sports turf and golf course maintenance

Installation Notes

For maximum accuracy, install the meter in a straight run of pipe with at least ten pipe diameters of unobstructed flow upstream and five diameters downstream. Use standard PTFE tape or non-setting pipe sealant on the MPT threads to ensure a leak-proof connection without over-torquing the housing. Ensure the arrow on the meter body aligns with the direction of water flow to prevent damage to the internal propeller mechanism and to comply with local water monitoring codes.
