1. A dispensing control system, comprising:
a frame component having a first side surface and a second side surface; and
a single pair of sensors for measuring an actual width of a liquid spray stream exiting a dispenser of a conformal coating machine, the single pair of sensors comprising:
a first sensor portion positioned proximate the first side surface; and
a second sensor portion positioned proximate the second side surface and facing the first sensor portion, the second sensor portion being separated from the first sensor portion a distance to allow the liquid spray stream exiting the dispenser to pass therebetween;
wherein the first sensor portion transmits a beam of light towards the second sensor portion to measure the actual width of the liquid spray stream that is unaltered after exiting the dispenser based on light not received by the second sensor portion, the beam of light having a width greater than the actual width of the liquid spray pattern, and contacting an entire width of the liquid spray stream while the dispenser and the first sensor portion and the second sensor portion are stationary.
