The Dosatron D14MZ2 is a high-flow, precise water-powered dosing unit designed for growers who require accurate nutrient or chemical injection into irrigation water. Ideal for commercial hydroponic, greenhouse and container systems, this unit ensures consistent additive delivery regardless of fluctuations in flow or pressure.

Features

• Adjustable dilution range from 1:500 to 1:50 (equivalent to 0.2% to 2%)
• Flow rate capability from 0.05 to 14 GPM (≈0.19 to 50 LPM)
• Operating pressure range from 4.3 to 85 PSI
• ¾″ NPT connection size
• Weight approximately 6 lb
• Dimensions ~19⅛″ x 6⅝″
• Built-in bypass option (depending on model variant)
• Compatible with a wide variety of liquid fertilisers, hydroponic nutrients and chemical additives

Benefits / Why It Matters

• Water-powered operation means no external power supply needed and direct integration into irrigation pipelines
• Ensures proportional injection: the unit meters the additive based on the water flow, so concentration stays consistent even if flow changes
• High flow capacity makes it suitable for large-scale systems
• Adjustable ratio gives flexibility across veg and bloom phases, nutrient programmes and different crop types
• Reliable dosing helps minimise nutrient waste, maintain stable EC/PPM and improve crop uniformity

Technical Specifications

• Dilution Ratio: 1:500 to 1:50 (0.2% – 2%)

• Pressure Range: 4.3 to 85 PSI
• Connection: ¾″ NPT
• Weight: ~6 lb (≈2.7 kg)
• Dimensions: ~19⅛″ × 6⅝″ (~486 mm × 160 mm)
• Included Accessories: Mounting bracket, suction hose with weighted strainer, quick start guide
• Materials: Available in polypropylene housing; seals and materials compatible with nutrient solutions

Installation & Setup Notes

You can find the Quick Start Guide and Owners Manual by clicking the links.

1. Install the unit in your main feed line, ensuring correct flow direction through the body of the doser.
2. Use recommended filtration upstream (to remove particles before suction tubing) and ensure pressure is within operating range for accurate dosing.
3. Set the dilution ratio based on the required additive concentration: e.g., for a 1:100 ratio set the dial accordingly.
4. Connect the suction tube into your additive reservoir; ensure the reservoir is vented or the tube remains submerged with clean feed.
5. Check and calibrate periodically to ensure accurate injection—especially when switching nutrient brands or additives.
6. Use the bypass facility (if present) when flushing or cleaning system without dosing.

Ideal Use Cases

• Commercial hydroponic or greenhouse setups where a stable additive injection system is needed
• Veg and bloom stages where different nutrient output concentrations are required
• Large-volume feed systems serving drip, ebb-and-flow or NFT benches
• Growers transferring between nutrient brands or injecting additional biostimulants or pH adjusters
