Sluice gates are one of the most common hydraulic structures in controlling flow rate and water level in open channels such as rivers and canals. They are also commonly used in waste water treatment plants and in watermills. In a remotely controlled sluice, it is important to know the degrees of opening of the sluice in order to control the flow of water that can pass. The INC series inclination sensor can give the information both with the analogue output and via the RS485 bus.
