Netafim M and WMR Series Water Meters

The Netafim M and WMR Series Water Meters are compact and robust, designed for agricultural and landscape applications. Here’s a summary of their features:

• Size & Design: Available in sizes 3/4", 1", 1 1/2", and 2", they are the industry’s smallest water meters, offering high performance and longevity. The M Series uses a multi-jet design for balanced impeller load and minimal wear, while the WMR Series features an in-line axial turbine to prevent clogging by foreign matter.

• Accuracy & Reliability: They provide ±2% accuracy across various flow rates. The M Series has a single moving part, the impeller, for reduced wear and reliability. The WMR Series’ wide clearances allow for full pipe flow measurements and high dependability.

• Specifications:

  • M Series:

    • Body Material: Copper Alloy or Polypropylene
    • Max Pressure: 140 psi
    • Max Temperature: 122°F
    • Register Options: Reed Switch, Photo Diode, ER Digital
    • Pulse Outputs: Varying by register type (e.g., 0.1 or 1.0 for Reed Switch)
    • Installation: No straight pipe requirements

  • WMR Series:

    • Body Material: Cast Iron with Polyester Coating
    • Max Pressure: 230 psi
    • Max Temperature: 131°F
    • Pulse Outputs: Varying by register type (e.g., 10 or 3.26 for Reed Switch)
    • Installation: Requires 10 x D upstream and 5 x D downstream (D = meter size)

Both series are equipped with magnetically driven, stainless steel encapsulated registers that prevent moisture accumulation and fogging. They are suitable for main supply lines where accurate and reliable water measurement is critical.
