MODEL 50386SE-105 : SDI-12 Shaft Encoder

General Description:

The Model 50386SE-105 SDI-12 Shaft Encoder is a low power shaft encoder designed for battery powered field operation for the measurement of water level or floodgate position. The internal microprocessor allows the encoder to emulate an absolute encoder. The user may set the initial water level, read and adjust subsequent levels through the SDI-12 interface. The encoder operates with standard float tape or bead chain pulleys and float hardware.
