Netafim 3/4 in Fertilizer Meter for Pulse-Based Fertigation
The Netafim 3/4 in fertilizer meter sends one pulse for every 0.1 gallon that passes, giving a controller 10 counts per gallon to work from. That resolution is fine enough for accurate batch dosing and totalizing on a fertigation line. The composite body handles up to 140 psi and threads into a 3/4 in run. Its reed-switch output wires straight into sensor-ready irrigation controllers.
Wiring a Pulse Output Water Meter into Your Controller
Growers plumb the meter inline on the 3/4 in main, usually downstream of the injector so it reads the mixed feed. The two pulse leads land on the controller's flow input, and each 0.1 gal tick logs volume in real time. That same signal flags a leak when water moves during a lights-out window. Composite construction stands up to fertilizer salts that corrode brass meters.
Key Features
- 0.1 gallon per pulse: Ten counts per gallon for precise dosing and totalizing.
- Reed-switch pulse output: Wires into sensor-ready irrigation and fertigation controllers.
- 3/4 in connection: Threads inline on a standard 3/4 in main.
- 140 psi max: Handles typical pump and municipal pressure.
- Composite body: Resists fertilizer salts that corrode metal meters.
