Providing safe drinking water to your customers is crucial for your business. As such, timely and reliable water quality information is invaluable to your water quality management decision-making process.
The upgraded QualitEye®-DW remote drinking water analyser takes water quality monitoring to another level. Built around the renowned Endress & Hauser Memosens water quality sensors with Liquiline transmitter/controller and the Ayyeka Wavelet IIoT device, the QualitEye®-DW has a unique feature set, designed to simplify the process of choosing a water quality monitoring/control system;
- Out-of-the-box, plug-and-play operation,
- Built-in sample conditioning module,
- Benchmark quality sensors for monitoring any or all of Free Chlorine, pH, ORP, Conductivity, Turbidity, Temperature and Line Pressure
- Input port for external flowmeter,
- Add or retrofit additional sensors including Total Chlorine, Microbial Activity (E. coli, Enterococci or Total Activity), Biofilm, Organics, Nitrate, Metals (Iron, Manganese, Arsenic and more),
- Multiple control outputs,
- Easily relocatable – all components are mounted in an IP 66 rated, lockable, UV stabilised GRP enclosure with polycarbonate window,
- Other enclosure types available to suit special requirements,
- SCADA connectivity,
- Cyber secure remote data transmission to our water quality intelligence system, Information Engine™.
Information Engine™ – D2K’s Water Quality Intelligence System


Couple the QualitEye®-DW to Information Engine™, and realise the power that lies hidden within the high-quality data;
- Attractive and intuitive User Interface shows you what you need to know,
- Configurable alerts based on parameter thresholds or complex scenarios,
- Data visualisation and downloads from multiple QualitEye® devices provides automated performance comparison across your systems,
- Data source agnostic design allows you to input a wide variety of relevant data – 3rd party sensors, SCADA data feeds, external on-line data feeds, CSV files, manual entry,
- Predictive algorithms (Risk Factors™) alert you to upcoming water quality events,
- Real-time performance reporting,
- Configurable, automated periodic reports,
- Specialist modules to improve the way you manage water quality
- Source Watch™, Treatment Watch™, and Distribution Watch™ – statistical process control rules-based modules provide line-of-sight over your entire water system supply chain. These modules incorporate predictive algorithms such as;
- Algaerithm™ – predicts the likelihood of an algal outbreak based on conventional water quality and other relevant data,
- Legionella Potential™ – predicts the likelihood of a water system being able to support the growth of Legionella bacteria,
- Ct Factor™ – provides early warning of failure of disinfection efficacy in the water treatment process,
- Naegleria Potential™ – predicts the likelihood of a water system being able to support the growth of Naegleria fowleri.
- CCP Watch™ – statistical process control rules-based module extracts deep insights from CCP water quality and other relevant data. Dramatically reduces the time spent manually sorting through and interpreting SCADA data,
- Audit Watch™ – simplifies, systematises and automates the process of auditing water quality management systems. Our template library is built from many years experience in leading water industry audits.
- Source Watch™, Treatment Watch™, and Distribution Watch™ – statistical process control rules-based modules provide line-of-sight over your entire water system supply chain. These modules incorporate predictive algorithms such as;
