Etatron eOne Micro-Doser Kit, 3/4 in Lo-Flo, for Dosatron Nutrient Delivery System

Etatron eOne Micro Doser Kit, 3/4 in Lo-Flo

Concentrated acids, bases and specialty additives often need doses measured in fractions of a milliliter per gallon. This kit brings that level of control to a 3/4 inch irrigation line. Its core is an Etatron eOne MF 01-10 electric metering pump with a backlit display. The pump is rated at 0.26 gallons per hour, which is 1 liter per hour, against 145 psi. A 3/4 inch water meter in the line sends the pump one pulse for every gallon that flows past. The pump answers with a set number of strokes, so injection tracks flow from moment to moment. Each stroke moves about 0.18 to 0.23 mL, depending on line pressure. A pressure relief valve between the pump and the injection valve sets back pressure and fine-tunes that volume. The mixing chamber blends the product into the water right after injection. A sunshade slips over the chamber to keep light off the solution. Unions, a check valve, a foot filter and PVC and polyethylene tubing finish the kit. It runs alone or alongside Dosatron dosers on a Lo-Flo Nutrient Delivery System.

Building the Micro Dosing System

The kit arrives as components, so plan the layout before cutting pipe. Start by fitting adapters and gaskets to the water meter. Assemble the union, check valve, nipples, tee, reducer bushing, mixing chamber and final union in sequence. Wrap each thread with tape and follow the flow arrows on every part. Mount the relief valve bracket and connect the discharge tubing from the pump head to the valve inlet. Run the valve outlet to the injection valve in the tee. Anchor the whole assembly securely to a wall. Route the water meter wires through the pump's rubber cap to terminals 3 and 4. Set the foot filter and suction tube in the chemical tank and prime in manual mode. Program the strokes per gallon by dividing the target dose by the pulse volume at line pressure. Check the result with a 100 stroke manual test and adjust the relief valve if needed. Slide the sunshade over the mixing chamber to finish.
