Suitability of light scattering technique for measurements of droplets in turbine wet steam flow depends on a variety of parameters. This paper examines all relevant aspects for droplet measurements inside low pressure steam turbines. On basis of light scattering theory, influence of these aspects for a distinct measurement of droplets is investigated. After clarification of these factors, a discussion on measurement errors is given comprising errors that lie within the physics of light scattering theory as well as those caused by the measurement configuration. Possible avoidance by selection of proper measurement equipment and an elaborate design and setup of the probe is described including an estimation on each errors significance on measurement results. Light scattering technique is then evaluated on its applicability for low pressure steam turbines. It is argued in favor of light scattering that only measurements of single droplets provide insight into the fundamentals of droplet condensation and growth during expansion. Requirements for measurements with a light scattering probe in steam turbines regarding the system's design and composition are pointed out. Finally an outlook on present and future developments is given.
