Water Level Sensors

Ott PLS-C

The Ott PLS-C Pressure Level Sensor with Conductivity is a precision instrument designed for simultaneous measurement of key hydrological and water quality parameters in surface water and groundwater monitoring applications. By combining a robust ceramic pressure cell with a 4-electrode conductivity sensor, the Ott PLS-C delivers stable, high accuracy data over long deployment periods, even in demanding field conditions. It’s extremely low power consumption makes it ideal for permanent installations and solar powered monitoring stations, where dependable performance and minimal maintenance are essential.

Measured parameters include:

• Water Level (vented)
• Pressure (vented)
• Temperature
• Conductivity
• Salinity
• Total Dissolved Solids

The Ott PLS-C is particularly suitable for:

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

Ott PLS-C Models

Available measurement ranges include:

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

Conductivity Ranges

The following Conductivity ranges are available:

• 5 – 2000µS/cm
• 0.1 – 100mS/cm

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).

Conductivity cell
4-electrode conductivity cell.

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