Applicable to aircraft engine nozzle pressure co-ntrol and measurement,
nozzle flow,spray angle,
spray uniformity and spray eccentricity measur-ement;
Direct read of spray angle eccentricity with angle scale and eccentricity scale,
safe and convenient observation with fiber optic light;
Spray uniformity measurement by measuring fuel coming from equally twelve divided fuel tray and collected to corresponding measuring cylinders;
With measuring cylinder system to collect fuel,
observe and discharge fuel.
