Abstract
A flush valve comprising: a valve housing defining a port; and a valve plate arranged to rotate in a plane, relative to the port, such as to vary a degree of coverage of the port by the valve plate depending on the rotational position of the plate; the flush valve further comprising: a component that rotates with the valve plate; a code formed of gradated markings provided on the component, the gradated markings formed such that a characteristic of the code varies across the component in the rotation direction; and a code reader, fixed relative to the valve housing, and positioned to read the code as it passes the code reader on rotation of the valve plate.
