A Flow Control Emitter is a small black and and blue barbed device which when inserted into the 1/4 inch ID black feeder tube portion of a T-Assembly connector allows a 1.0 gal/hr flow rate into an Irrigro drip tubing line regardless of the upstream water pressure. The minimum upstream water pressure required is 10 psi and therefore it cannot be used with a gravity tank installation. The maximum upstream water pressure is 70 psi. The blue side must face the upstream water flow when inserted into the feeder tube portion of the T-Assembly connector.
