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

Etatron Dosing Pump on an Assembled Panel, 3/4 in

Plumbing a micro-doser from loose fittings takes an afternoon and a careful eye for arrow directions. This panel arrives with that work already done on a polyethylene backboard. Water enters the 3/4 inch plumbing on the left side and leaves on the right. The pump is an Etatron eOne MF 01-10, a microprocessor diaphragm pump with a backlit graphic display. It is rated at 0.26 gallons per hour, which is 1 liter per hour, at 145 psi. The pump can run up to 180 strokes per minute. A water meter on the panel sends one pulse for every gallon that passes. The pump turns those pulses into proportional doses, so injection follows flow rather than a timer. Each stroke delivers roughly 0.18 to 0.23 mL, depending on line pressure. A pressure relief valve sits between the pump head and the injection valve to set back pressure. A check valve, unions, a foot filter and a mixing chamber complete the assembly. Typical uses include pH down, pH up, plant health additives and water treatment products.

Running the Micro Doser on a Lo-Flo Line

Anchor the panel to a wall where the line runs from left to right. Connect the inlet and outlet unions to the irrigation line. The panel can run beside Dosatron water-powered dosers on a Nutrient Delivery System or on its own. Micro-doser systems in this pipe size cover roughly 0.5 to 20 GPM of line flow. Drop the foot filter and PVC suction tube into the chemical container, which is not included. Prime the pump in manual mode until product reaches the injection valve. Next, program the number of strokes per gallon. Divide the target volume per gallon by the single pulse volume at the working pressure, then round to the nearest whole number. Turning the relief valve screw clockwise raises back pressure and trims each pulse slightly. To check the real pulse volume, run 100 strokes in manual mode and measure what the pump draws. Check the foot filter for debris each time the chemical container is changed. Follow local backflow rules when the panel connects to a public water supply.
