- The OTT Orpheus Mini is an integrated pressure sensor and datalogger for level measurement in surface and groundwater applications. It features a robust ceramic measuring cell for long term accuracy and its built in datalogger manages and stores all measurements at user-programmable intervals. The Orpheus mini can be paired with the OTT ITC for remote data transmission.
- Accurate– Ceramic pressure cell, unlike membrane technology, will not deform over time providing long-term measurement stability
- High Performance– Mechanical resistance to pressure overload and corrosive waters
- Complete Solution– Pressure sensor with built-in data logger manages and stores pressure, depth to water, water level (stage), and/or temperature measurements at programmable intervals
- Flexible Installation– Easily installs in wells or pipes of 1 in. diameter or larger with use of convenient adapter plates
- Simple Maintenance– Infrared interface, batteries, and desiccant are accessible at the top of the well or pipe and no tools are required
- For continuous or continuous real-time water level measurement of:
+ Streams, rivers, channels, or canals
+ Groundwater wells
+ Reservoirs, lakes, and wetlands
- Ideal for monitoring:
+ Continuous water level networks
+ Short-term or long-term
+ Events
+ Pump tests
+ Landfill groundwater levels
