ABB’s new Navigator 500 analyser family brings a compact, reliable and accurate range of instruments for high purity water treatment and boiler chemistry monitoring applications. Providing continuous online monitoring of boiler feed water quality, the Navigator 500 hydrazine, dissolved oxygen and sodium analysers help ensure optimum efficiency of both boiler plant and ancillary equipment throughout the steam distribution loop. The second in the Navigator analyser series, the Navigator 500 series joins ABB’s Navigator 600 silica and phosphate devices for power generation applications.
A key feature across the Navigator 500 series is its separate sensor and transmitter section design. All analysis and signal conditioning is conducted within the sensor section and transmitted digitally to the transmitter. Each transmitter can collect data from up to four sensors. This enables monitoring at multiple points without the cost associated with purchasing and installing separate transmitters. The four transmitter inputs can be used to collect signals on one parameter or can be mixed and matched, with multiple parameters being fed to one unit. In contrast to traditional single-stream devices, the Navigator 500 Sodium sensor can also be configured for multi-stream analysis, with up to three sample streams able to be handled by a single sensor unit.
Each analyser within the Navigator 500 series is based on ABB’s proven chemical analysis technology. The Navigator 500 hydrazine is used for applications where hydrazine is used to dose boiler feed water to reduce dissolved oxygen levels. The sensor uses an electro-chemical cell to measure the amount of hydrazine in the water. This accuracy is reinforced by temperature compensation, which, coupled with a fast response time, helps ensure that readings reflect the actual feed water conditions. The information provided by the analyser makes it possible to avoid expensive overdosing of hydrazine or the avoidance of more costly corrosion damage to the boiler plant due to the under-dosing of hydrazine. The Navigator 500 dissolved oxygen uses a galvanic-type sensor to measure dissolved oxygen levels in process feed water. It can be used to measure dissolved oxygen throughout the feed water system as well as an indicator of hydrazine dosing efficiency. Accurate and reliable, it requires no maintenance and monitors dissolved oxygen levels across a wide spectrum up to 20 parts per million.

At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
