The OTT Thalimedes float-operated shaft encoder level sensor and logger takes proven level measurement technology to the next stage. Designed for continuous, unattended monitoring in ground and surface water applications, the Thalimedes is a very low cost solution for new measuring sites and is extremely easy to connect to existing paper chart recorders, making a digital upgrade simple and cost-effective. Easy to use, highly compact and self-contained, the entire instrument can fit in well pipes as small as 4" in diameter. A digital interface offers the added convenience of remote monitoring from the office or field.

Features:

• Easily mounts in 4, 5 or 6-inch pipes with optional pipe mount kit
• Measuring range: 200 feet
• Integral data logger stores up to 30,000 measured values, with sampling and logging intervals that can be preset from 1 minute to 24 hours for maximum flexibility
• Motion-activated LCD displays level value, time, date and battery status
• Autonomous, low maintenance operation for up to 15 months with a single C-cell battery that's easy to replace – no tools needed
• Remote communications via SDI-12
• RS232 interface enables data transmission via land line or cellular modem, radio or satellite
• Infrared technology allows wireless, cable-free data transfer locally between instrument and nearby laptop

Benefits:

Time-tested, the highly reliable float and pulley mechanism of the shaft encoder is activated by even the slightest changes in water level, providing highly accurate water level measurements every time; and the SDI-12 interface offers the industry standard for reliable, digital output. An integrated 30,000-value datalogger makes this an extremely affordable, stand-alone level logging system.
