CENTRAL ILLINIOS | Could be the flow meter gone bad. I don't know how to check it other than try a different one. Could be the cooling tower is not functioning. They evaporate some of the NH3 to keep the rest cold and in liquid form so it can be metered. If it is sending both gas and liquid through the system that will make the rate jump all over. A piece of dirt in the orifice at the top of the cooling tower could be the problem there. You can unhook your vapor lines and visually observe as you go through the field if there is vapor coming out. Also make sure your ground speed is not jumping around. | |
