OTT PLS 500
Piezometric water level sensor
OTT PLS 500
The OTT PLS 500 is a high-precision piezometric sensor designed for accurate measurement of water level, depth, pressure, and temperature in both groundwater and surface water. Built with four internal compensations, a durable stainless steel housing, and a robust cable, it delivers reliable performance across a variety of applications.
Common communication protocols enable seamless operation with external data loggers, while precise temperature measurements and the built-in microcontroller compensate for environmental changes in water density.
Automatic
compensations
Thanks to automatic compensation for atmospheric pressure changes, improved accuracy is achieved with a single sensor.
Customized
cable
Thanks to the customizable cable length, users encounter no issues regardless of the application.
Internal
humidity sensor
Automatic humidity measurement extraction enables the detection of condensation formation.
Discharge
calculations
Minimizing the need for data post-processing with direct flow output from a reliable level sensor.
Wide range of applications
Ideal for installation in small-diameter pipes, dams, irrigation systems, saltwater, retention basins, and more.
High
accuracy
Reliable measurements with a recording resolution of 0.1 mm for depth and 0.10 °C for temperature.
Why opt for OTT PLS 500?
Position sensor
The user can remotely monitor the movement of the sensor in the field through an internal inclinometer. This ensures the sensor remains in the correct position at all times, with alerts available in case of displacement due to high flow conditions.
Data processing
It internally converts high-frequency measurements into calculations such as averages, minimum/maximum levels, and instantaneous values at user-defined intervals. This enables more informative reporting while eliminating the need for manual data processing or analysis.
Range of applications
It features a ceramic pressure element resistant to physical force, along with a high-quality housing that withstands even seawater. The robust ceramic pressure cell, offering industry-leading accuracy, does not deform over time, ensuring long-term measurement stability.
