    Droplet size measurements obtained by sampling at discrete spray plume locations were compared to those obtained by sweeping the spray plume from fan nozzles through the sampling area of a laser droplet imaging probe. A mixture of water, 2.5% Tenneco 500/100 solvent and 0.5% Titron X-100 adjuvant was sprayed through flat spray and even flat spray nozzles. The distribution of spray volume across the spray plume, Dv0.5, % volume <204 μm, % volume >415 μm and % volume between 204 and 415 μm are presented for discrete location and sweep methods of sampling.
