Application: Surface water, Groundwater
Measurement technology: Vented pressure cell
Parameters measured: Water level/Pressure, Water temperature
Product Highlights: Measures and stores water level and temperature data
Measurement range: 0 … 4, 10, 20, 40, and 100 m
Accuracy: ± 0.05% FS
Internal data logger: Yes
- FEATURES
-
- 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
