New Low-Cost Non-Intrusive Heat Flux and Corrosion Monitors
These stand-alone units are designed for heat flux and corrosion monitoring at point locations on boiler
membrane walls and other industrial applications. They use the principle of electrical resistance
measurement to accurately determine the real heat flux and any loss-in-thickness (corrosion or erosion) of
heat transfer surfaces.
Non-intrusive sensors are simply welded to external tube walls as opposed to intrusive heat flux probes which require tube removal and replacement.
Straight-forward installation, multiple interface options with plant information systems.
Rowan Technologies Ltd, established in 1991, provides a diverse range of services and systems related to
engineering material performance, monitoring, integrity and preservation. The company’s expertise ranges
from industrial plant integrity and performance, including corrosion and thermal monitoring, to historic
building conservation and cathodic protection systems. Our clients include many major UK and overseas
Scanner Installations - Samcheonpo Power Station, South Korea
Lead Roof Inspection - Thaxted Church, Essex, UK
VTER Corrosion Probes - Drax Power Station, UK
Scanner Installations - Yeongheung Power Station, South Korea
Cathodic Protection System - Wellington Arch, London
Scanner Installation - Martin Lake Power Station, Texas
Concrete Conservation - Tynemouth Priory, Tyne & Wear, UK
We design and supply a range of systems for monitoring both the integrity (corrosion, erosion and cracking)
and thermal behaviour of industrial plants. Our scanner technology, designed to monitor and map large areas
of plant such as boiler walls, has been used in power generation plant since 1999. New in 2015,
'mini-scanners' now complement these larger systems and are designed for smaller monitoring areas. Also
introduced in 2015 are our new heat flux monitors, designed for precision monitoring at point locations.
We provide services and systems for corrosion risk assessment, prevention and control, and specialise in the
design and supply of cathodic protection systems to inhibit the corrosion of embedded metalwork in masonry
and concrete. As advisers to English Heritage, we have extensive experience in the preservation and
conservation of historic structures, including some of the UK’s best known buildings.
Services include consultancy, failure analysis and environmental monitoring and we have (or have access to)
a wide range of analytical instrumentation, measurement and test facilities. We have received a number of
technical awards for our research and development activities: our development projects include ceramic
thermocouples, ideally suited to high temperature (greater than 1500°C) and highly corrosive
