| I agree with what Wilgar said. But, again can't give a good explanation. The orifice will control the flow from that point out, correct, but it can't control what doesn't come to it. If you have a common flow coming to Wilgars, then breaking it out to individual rows after the gauge, it makes sense. The longer the hose, the more resistance there is for that row. So each row has the orifice resistance + resistance that is determined by hose length. The longest hose has the greatest resistance, there for less fertilizer will enter that particular site gauge and will be diverted to the one with less resistance.
Also, even if you have a manifold prior to gauges that splits the flow to each row then the gauge then the orifice, the concept still applies. Only difference is flow will be redirected or distributed differently at the manifold point not at the gauges.
