With the modular IQ Sensor Net of the brand WTW, Xylem has set standards in the field of continuous on-line measurement. Meanwhile, Xylem can look back on a 20-year success history with ten thousands of systems and sensors sold. The development of the system has progressed steadily. The list of available parameter measured and the technologies for communication continue to grow. Based on instrument and sensor technology that has been field-proven many times over, IQ Sensor Net offers an impressive level of performance and flexibility that is unique in this form.

The system can be optimally adapted to any conceivable measurement task, even under special on-site conditions. The IQ Sensor Net communication system allows the easy integration of multiple measurement locations. This results in a significant reduction in costs while maintaining full functionality.
