Biotrace Ltd has applied embedded Linux and Open Source Software (OSS) in a Continuous Flow Luminometer for remote monitoring and control of biological activity in cooling water towers. At present, a technician has to visit each site, take a sample, measure it, and introduce a biocide to the water if the biological activity is too high. The improved system removes this operating cost, opens up a new market of over 45,000 cooling water towers in the UK alone, and will deliver a projected rate of return of 347 percent.

Biotrace Ltd. currently specializes in the design, development and manufacture of chemicals and instrumentation for hygiene monitoring applications in the food preparation, health product, industrial and military application markets. The company's product range incorporates chemicals and the related packaging, swab and related disposable equipment, and a range of measurement instrumentation designed to measure fluorescence or colour changes in these chemicals when chemical or microbiological reactions take place.
