Netafim 3/4" Plastic Water Meter, 0.1 Gallons per Pulse

Follow these steps to accurately integrate your meter into the irrigation mainline.

Step 1: Install the Air Vent
Install a continuous acting air vent immediately upstream of the Netafim meter. This prevents air pockets from passing through the chamber, which can cause falsely high flow readings.

Step 2: Position the Meter
Thread the 3/4" water meter inline with your system using the appropriate threaded fittings. Ensure the flow direction arrow on the meter body points toward your plants.

Step 3: Wire to the Controller
Run the pulse output wires from the meter to your compatible smart irrigation controller. Securely connect them to the designated sensor or flow meter terminals.

Step 4: Configure the App
In your smart controller's settings or app, select "Flow Sensor" and input the K-factor or set the pulse rate to 0.1 gallons per pulse to ensure the controller calculates usage correctly.

How do I prepare the Netafim 3/4" Plastic Water Meter for spring startup?
To prepare the Netafim 3/4" Plastic Water Meter for spring, slowly open your main valve to gradually pressurize the system, preventing water hammer. Check the meter body and wiring connections for any winter damage before running your controller.

Opening the valve too quickly can send a rush of air and water that spins the internal register too fast, potentially damaging the components. Always start slow.

What is the maximum pressure rating for the Netafim 3/4" Plastic Water Meter?
The Netafim 3/4" Plastic Water Meter has a maximum operating pressure of 140 PSI, making it highly durable for both residential and commercial irrigation systems.

While the meter can withstand up to 140 PSI, you should still install a pressure regulator downstream of the meter and valves to protect your delicate drip tape and emitters.

Does the Netafim 3/4" Plastic Water Meter require an air vent for accuracy?
Yes, installing a continuous acting air vent immediately upstream of the Netafim 3/4" Plastic Water Meter is highly recommended. This removes trapped air, ensuring the meter only measures water for accurate flow readings.

Without an air vent, air passing through the pipe can spin the meter's internal turbine, causing your controller to report higher water usage than what was actually delivered.

How does the 0.1 pulse rate work on this Netafim Water Meter?
This Netafim 3/4" Plastic Water Meter uses a built-in sensor that sends an electrical pulse to your controller for every 0.1 gallons (1/10th of a gallon) of water that passes through.

This ultra-fine resolution provides highly granular data, making it ideal for micro-irrigation systems, small garden zones, or sensitive greenhouse watering schedules where pinpoint accuracy is required.
