Multi-parameter (sensor) system

WTW IQ Sensor Net description

The IQ Sensor Net is a continuous on-line water quality measurement system which uses digital communications to interface between all connected components. The controller may communicate with one or more sensors, over significant distances. Several digital controller models are available that provide unrivalled choice and flexibility whilst maintaining commonality of component and user familiarity. Internal data logging and graphical representation is available (model dependent). The instrument also provides a high level of diagnostic capability to provide additional confidence in the operation and functionality of the measurement system.

Whist the system is primarily designed for on-line measurement with mains power supply connection, PPM have also adapted the measurement technology with interchangeable lithium-ion battery packs, for temporary installation. This approach allows the best possible measurement quality, for short term environmental surveys and treatment plant, process design.

The submersible probes are of robust stainless steel or titanium construction providing the optimum protection. The technology is suitable for water and water-water applications. Installation into small tanks, pipes and flow cells, provides complete installation flexibility.

TriOS Tribox description

Two digital controllers are available enabling up to two or four sensor connection to a common controller. Provision of automatic compressed air cleaning and option for integration of ultrasonic cleaning for flow through measurement, satisfy the more challenging waste water applications. TriOS range of optical probes of stainless steel or titanium construction, provide the very latest measurement technology for dissolved organics, UVT, colour, nitrate, nitrite and oil in water. The e-chem range allows for measurement of pH, conductivity, dissolved oxygen, turbidity and suspended solids, which are also supported by well-engineered flow cells, of a modular design.
