The report describes the design, development, and field testing of a concept to measure liquid droplets in the size range from 1 to 600 micrometers. The measurement probe is a platinum wire 5 micrometers in diameter. With the probe electrically heated to a predetermined temperature, changes in the probe resistance are related to the size of the impinging droplets in the gas flow. The electrical signals from the probe are processed and used to classify the droplets into six different size ranges or bins. Two prototypes, consisting of the probe and electronic processing unit, were constructed and tested in the field. Actual droplet distributions and concentrations were measured successfully.
