A measurement head for making X-ray measurements on drilling fluid includes an inner pipe () having a outlet () and an outer pipe () around the inner pipe. Drilling fluid is pumped through the outlet refreshing the fluid at the outlet. The pump is then stopped. A height sensor () is then used to measuring the height of a meniscus of drilling fluid at the outlet (). An X-ray head () including an X-ray source () and an X-ray detector () is then moved into a reproducible position above the meniscus of fluid above the outlet. The height sensor () may be fixed to a movable cover (), to the X-ray head () or to some other part of the measurement head.
