AMI Sample Sequencer – Multi-Stream Monitoring for Efficient Water Analysis
In power plants and industrial water systems, multiple sampling points must often be monitored to maintain full control of water chemistry.
The SWAN AMI Sample Sequencer allows you to connect multiple sample streams to a single analyzer, enabling sequential measurement across several sampling points. This reduces the need for multiple analyzers while still providing reliable monitoring of critical parameters.
With automated sample switching, you can optimize your monitoring setup and reduce both investment and maintenance costs.

Automated switching between multiple sample streams
The AMI Sample Sequencer distributes multiple sample lines to one analyzer by automatically switching between sampling points.
The system operates by:
- connecting several sample inlets
- selecting one sample at a time
- allowing stabilization before measurement
- repeating the cycle continuously
This ensures that each sampling point is measured under stable and controlled conditions, providing reliable data from multiple locations.
Part of a Steam & Water Analysis System (SWAS)
The AMI Sample Sequencer is often used as part of a Steam & Water Analysis System (SWAS), where multiple sampling points from the steam-water cycle are monitored using a combination of analyzers.
SWAS systems enable continuous monitoring of parameters such as conductivity, silica, oxygen, and sodium to protect boilers and turbines from corrosion and deposits.
Key features supporting efficient multi-point monitoring
- Sequential measurement of multiple sample streams with one analyzer
- Automatic switching between sampling points
- Configurable measurement and stabilization times
- Reduced number of analyzers required
- Optimized use of existing instrumentation
- Reliable operation with controlled sample handling
- Integration with SWAN analyzers and control systems
These features help you monitor more points with fewer instruments while maintaining reliable data quality.
Typical applications in power and industrial systems
The AMI Sample Sequencer is used in systems where multiple sampling points must be monitored efficiently.
Typical applications include:
- Power plant steam-water cycle monitoring
- Multi-point monitoring in SWAS systems
- Condensate and feedwater systems
- District heating plants
- Industrial water and utility systems
By switching between multiple sampling points, you can cover more of the process without installing separate analyzers at each location.
Benefits for your operation
With a sample sequencer you gain:
- Reduced investment in analyzers
- Lower maintenance and calibration requirements
- Efficient monitoring of multiple sampling points
- Flexible system configuration
- Reliable data from different parts of the process
These benefits support cost-effective and scalable water quality monitoring.
