Water Level Sensors

PLS

The OTT PLS is a robust & accurate water level sensor designed for measuring:

• Water Level (vented)
• Pressure (vented)
• Temperature

The PLS is particularly suitable for:

• Groundwater wells.
• Streams, rivers, channels & canals.
• Reservoirs, lakes & wetlands.

PLS Models

Available measurement ranges include:

• 0m – 10m
• 0m – 20m
• 0m – 40m
• 0m – 100m

Ceramic Pressure Cell
The robust ceramic pressure cell offers industry-leading accuracy and does not deform over time like membrane technology, providing long-term measurement stability.

Rugged Design
Ceramic pressure cell resistant to physical force (5 x burst pressure) and enclosure made of high quality saltwater resistant steel for use in coastal environments.

Auto Compensation
Built-in microcontroller compensates for temperature effects and applies correction values for gravitational acceleration and water density.

Vented Pressure Probe
Th vented pressure probe automatically compensates for changes in barometric pressure.

Simple Setup
Simple setup and connection to external dataloggers using SDI-12 or 4-20 mA interfaces.

Temperature Measurement
Water temperature output in addition to water level (for SDI-12 output).

Construction & Cables

Designed with continuous deployment in mind, this Logger incorporates a ceramic pressure sensor within a salt water resistant 904L stainless steel housing.

All PLS units are manufactured with custom cut vented cables.  Users to specify cable length upon order.

Communication Options

Common communication protocols (SDI-12, RS-485 and 4/20mA) allow for seamless integration with external data loggers.
