A flush valve comprising: a valve housing (10) defining a port (20); and a valve plate (30) 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 (62) that rotates with the valve plate; a code (70, 70', 70") 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 (75), fixed relative to the valve housing, and positioned to read the code as it passes the code reader on rotation of the valve plate.
