Netafim Liquid Filled Pressure Gauge

The Netafim Liquid Filled Pressure Gauge is a compact irrigation monitoring instrument that reads water pressure in either a 0–30 PSI or 0–100 PSI range. Designed to work with the Netafim 17 mm Combination Tee, it gives growers a direct, readable pressure reading at the line—useful for confirming that drip emitters and distribution tubing are operating within their intended pressure window.

Why Choose the Netafim Liquid Filled Pressure Gauge

Liquid-filled gauges differ from dry gauges in one important way: the glycerin or glycol fill dampens needle vibration caused by pressure pulses in an active irrigation line. This makes the dial easier to read when the system is running, and it reduces mechanical wear on the internal Bourdon tube over time. For growers running drip or micro-irrigation systems, that translates to a more stable reading under real operating conditions.

• Two pressure ranges available: the 0–30 PSI variant suits low-flow drip lines and emitter networks where operating pressures are typically below 20 PSI; the 0–100 PSI variant covers higher-pressure mainlines and supply feeds.
• Designed to pair with Netafim fittings: the gauge threads directly into the Netafim 17 mm Combination Tee, so installation in an existing Netafim drip layout requires no adapters or additional hardware.
• Liquid-filled dial: the internal fill absorbs line vibration and minor pressure spikes, keeping the needle steady and reducing false readings that can occur with dry gauges in active systems.
• Compact and lightweight: at 0.50 lb, it adds negligible load to a tee fitting and can be installed in line without stressing the tubing or fittings around it.
• Simple, direct reading: no electronics, no calibration required—pressure is read directly from the analog dial in PSI.

Best Uses for the Netafim Liquid Filled Pressure Gauge

This gauge is most useful when you need to verify or troubleshoot pressure conditions at a specific point in a drip or micro-irrigation circuit. Common deployment scenarios include:

• Drip irrigation line verification: confirm that water pressure at the emitter zone is within the operating range specified for the drip emitters being used. Most pressure-compensating drip emitters have a minimum inlet pressure requirement; a gauge installed upstream at the distribution tee confirms that requirement is met.
• Pressure regulation checks: if a pressure regulator is installed upstream, a downstream gauge reading confirms whether the regulator is functioning correctly or has drifted out of range.
• Filter monitoring: installed on either side of a line filter—such as a mesh screen filter—the gauge helps identify when filter loading is causing a pressure drop that affects emitter performance.
• Hydroponic recirculating systems: on nutrient delivery loops where consistent flow and pressure are needed to maintain even distribution across a run, a gauge at key junctions helps identify restrictions or pump output changes early.
• Commercial greenhouse and controlled-environment grows: in large-scale drip layouts with multiple zones, individual zone pressure gauges make it straightforward to identify which zone is running low or high relative to the rest.
• New system commissioning: during initial setup of a drip network, pressure readings at various points along the main and sub-mains help confirm that the system was sized and installed correctly before plants are introduced.

Compatibility

The Netafim Liquid Filled Pressure Gauge is designed to install into the Netafim 17 mm Combination Tee. The 17 mm Combination Tee is a standard fitting in Netafim’s 17 mm distribution tubing line, which is widely used in both agricultural drip irrigation and indoor hydroponic drip systems. If you are working with a Netafim 17 mm distribution layout, this gauge threads directly into the tee port without additional adapters.

For use outside of a Netafim 17 mm fitting, you would need to confirm that the gauge’s inlet thread matches the port on your chosen tee or manifold fitting. The canonical product data does not specify thread size or type beyond the Netafim 17 mm Combination Tee pairing, so verify thread compatibility before ordering for non-Netafim fitting installations.

If your grow setup includes water quality management upstream of irrigation—such as a compact reverse osmosis system feeding your reservoir—monitoring pressure at the drip distribution point is a useful way to separate supply pressure from any pressure losses occurring within the distribution network itself.

This gauge does not require electrical power, a controller, or any additional sensors to operate. It is a fully passive, mechanical instrument that reads pressure from the line it is installed on.
