Water Treatment Instrumentation
Accurate Monitoring and Control for Industrial Water Systems
AllWater Technologies supplies a comprehensive range of water treatment instrumentation designed to support the safe, efficient, and compliant operation of industrial and commercial water systems. From process sensors to precision water analysis instruments, our solutions help you monitor key parameters, detect faults early, and maintain optimum performance across every stage of treatment.
Whether you need real-time pH control for a chemical dosing system or flow meters for an effluent discharge line, we deliver dependable instrumentation backed by expert guidance, integration support, and full documentation.
Why Instrumentation Matters in Water Treatment
Precise measurement is critical in modern water treatment systems. Without accurate and responsive instrumentation, treatment processes risk underperformance, environmental non-compliance, and damage to downstream equipment.
Our monitoring instruments for water systems allow operators to:
- Track system health and water quality in real-time
- Adjust treatment parameters dynamically based on live data

- Comply with industry regulations and discharge permits
- Detect anomalies early and prevent costly failures
- Optimise chemical dosing and energy use
By incorporating smart instrumentation, businesses can improve control, reduce waste, and extend the lifespan of their systems.

- Real-time trending and historical data storage
Systems can be housed in IP-rated enclosures or supplied in full control panel assemblies, with optional cloud connectivity for remote monitoring.
Instrumentation Panels and Packages
In addition to individual sensors, AllWater also supplies pre-engineered or bespoke instrumentation panels. These are ready-to-mount assemblies containing flow cells, pipework, valves, and transmitters for one or more process parameters.
These are ideal for:
- New plant installations
- RO/EDI skid integration
- Final effluent monitoring stations
- Compact installations where space is limited
We offer panels fully prewired and pre-tested, with easy connection to external signals, simplifying installation and commissioning.
