Etatron eOne Micro-Doser Assembled Panel, 3/4 in Lo-Flo, Right to Left Flow

Etatron eOne Micro-Doser, Right to Left 3/4 in Panel

Irrigation rooms rarely leave a choice about which way the main line runs. This panel is built for a line that flows from right to left across the wall. Dilution Solutions mounts every part on a polyethylene board and plumbs it at the factory. At the center sits an Etatron eOne MF 01-10, a microprocessor diaphragm pump with a backlit graphic display. Its rated output is 0.26 gallons, or 1 liter, per hour against 145 psi. Stroke frequency reaches 180 impulses per minute. Upstream, a water meter sends the pump one pulse for each gallon of water that passes. The pump converts each pulse into strokes, so dosing rises and falls with flow. Depending on line pressure, a single stroke moves roughly 0.18 to 0.23 mL of concentrate. That precision suits acids, bases, plant health additives and water treatment chemistry. The pump head sends product through a pressure relief valve before it reaches the injection valve. A check valve, unions, foot filter and mixing chamber complete the board.

Setting Up the Micro Doser Panel

Choose a wall section where the irrigation line enters from the right. Fasten the panel securely, then join the line to the unions at each end. The board can work alone or alongside water-powered Dosatron dosers on a Nutrient Delivery System. On 3/4 inch pipe, micro-doser setups handle about 0.5 to 20 gallons per minute. Supply a chemical tank, since none comes with the panel. Set the foot filter at the bottom of the tank on the PVC suction tube. Use the pump's manual mode to prime the line until product appears at the injection valve. Program the strokes per gallon from the target dose and the pulse volume at line pressure. Round that result to the nearest whole stroke. A clockwise turn on the relief valve screw adds back pressure and slightly reduces each pulse. Confirm the setting with a 100-stroke manual run, measuring the volume the pump draws. Install backflow protection where local rules require it on a public supply.
