Integrated conductivity sensors in water treatment systems

Conductivity is the primary measurement of mineral contamination in water and as an on-line measurement it provides inexpensive, reliable monitoring of water quality through the various stages of treatment. Benefits of using a single, wide-range sensor for all stages of water treatment include savings in specification, procurement, installation, start up, training and maintenance. Requirements for instrumentation spare parts are also greatly reduced, because a single model works with all parameters without hardware or configuration changes, greatly improving system simplicity and reliability.

A single wide-range UniCond® integrated conductivity sensor, from Mettler Toledo can measure accurately from ultrapure water up to 50,000 μS/cm using its comprehensive automatic internal auto-ranging. This remarkable rangeability covers all measurements of most water treatment systems so the sensor becomes universal, allowing for straightforward specification, documentation, installation, wiring, operation and planning.

Mettler Toledo’s conductivity sensors feature convenient plug-and-measure functionality which greatly reduces the chances of operator error, with on-board memory to maintain sensor identity, calibration data and sensor diagnostics information. Sensors can be calibrated before installation in the process, with no special handling required to prevent operator error. Key information such as measurement parameter, part number, serial number, factory and user calibration data, and diagnostic factors are immediately recognised when a sensor is connected.
