                                                • STS offer rangeable submersible transmitters for Depth and Level applications where the maximum water level might change and maximum output resolution is required. Alternatively, they are ideal for standardizing on a single type of device to satisfy a multiple number of installations. These are generally programmable through a digital interface such as RS485.
