The CS410 is a shaft encoder designed for water level measurements. A pulley attached to a a float and counter-weight rotates as water level rises or falls, and the shaft encoder sends two pulse strings to the datalogger. The datalogger records the pulse strings, and the water level is calculated by adding and subtacting the clockwise or counter clockwise movement to a running total. | |

The SSR100 is an integrated system that monitors and records water level. It consists of a shaft encoder and a Campbell Scientific datalogger housed in an environmental enclosure. The system is pre-programmed to measure the shaft encoder, a tipping bucket rain gage, and an SDI-12 sensor. An alphanumeric LCD inside the enclosure displays the real-time measurements. A High Data Rate GOES satellite transmitter can be added to the system to transmit measurements via Geostationary Operational Environmental Satellites (GOES). | |
