Netafim 1in Fertilizer Meter 1.0 Pulse/Gallon

Netafim Fertilizer Flow Meter for Automated Fertigation Measuring stock solution as it flows is the most direct way to know what each crop actually received. A meter on the fertilizer line lets the controller dose by measured volume rather than by run time. This Netafim unit is the 1 in PVC model, item 70261-011300, model 36FMPVE1. It is an angle type multi-jet meter, so the flow turns through the body and spreads evenly around a single impeller. That impeller is the only moving part touching the liquid, which keeps wear low and accuracy steady. A magnetic coupling drives the sealed register, and the register is built so it will not fog or collect moisture. The same coupling trips a reed switch that sends a dry-contact pulse for every 1.0 gallon. Accuracy is ±2% across a range from 1.08 GPM minimum to 44 GPM maximum, with 22 GPM nominal. The PVC body is rated for 145 psi and liquids up to 122°F, with threaded connections. It measures about 6 in tall and 4-3/4 in wide and weighs 1.9 lb. Installing a Netafim Fertilizer Meter on the Injection Line Netafim designs this meter for fertilizer control in automated irrigation systems. Wire the reed switch to the pulse input of the fertigation or irrigation controller, which then counts gallons of stock solution as they pass. When the count reaches the target for a cycle, the controller can stop the injector rather than guessing from run time. Comparing the pulse count against water meter readings also shows the real injection ratio over a day. Install it horizontally with the dial face up, as Netafim specifies. There are no straight pipe requirements, so it can sit right next to an injector, filter or check valve. Corrosion resistant plastic components stand up to fertilizer concentrate. A tamper proof seal on the PVC meter shows if anyone has removed or opened the register. The dial totals in gallons, with pointers resolving down to tenths of a gallon for manual checks. Every meter is individually tested and calibrated, and Netafim covers the metering parts for three years and the body for five. Key Features • Reed switch output: One dry-contact pulse per gallon for fertigation controllers and loggers. • ±2% accuracy: Holds from 1.08 GPM up to the 44 GPM maximum. • Angle multi-jet PVC body: Spreads load evenly on the impeller and resists corrosive solutions. • 145 psi rating: Handles pressurized injection lines up to 122°F liquid temperature. • Tamper proof seal: Shows at a glance whether the register has been removed or tampered with. • No straight pipe needed: Mounts close to injectors, filters and check valves.
