The RIVERT and RIPOS-HART absolute rotary encoders, a system for precise position and angle measurement, are suitable for a wide range of applications in hydro-infrastructure (water management). The universal RIPOS and RIVERT encoders cover a wide range of applications for measuring the angle, position, distance or actuating speed of various structures, such as weirs, ball valves, butterfly valves, drawbridges, sluice gates or travelling and slewing cranes.
