Rosemount's Analytical Model TCL system significantly reduces total cost of ownership while delivering continuous chlorine measurement. Emerson Process Management is offering the Rosemount Analytical Model TCL, a complete system for the measurement of total chlorine in water, including seawater. The new Model TCL, comprised of a sample conditioning system, an analyser and a sensor, significantly reduces cost of ownership over previous generation total chlorine systems by employing readily available, low-cost reagents, and reducing the frequency of reagent replacement by as much as eight times.
The system uses a proven analysis methodology and was designed to minimise maintenance requirements and operating costs. At the same time, the Model TCL provides a continuous measurement as opposed to a periodic sample measurement. Continuous analysis is required for systems where control will be used.
The sample conditioning system of the Model TCL continuously injects a solution of acetic acid (vinegar) and potassium iodide into the sample. The acid lowers the pH to between 3,5 and 4,5, and allows total chlorine in the sample to quantitatively react with the potassium iodide to produce iodine. The sensor measures the iodine concentration, and the analyser displays the total oxidant concentration in ppm as Cl2. Because the system requires only distilled white vinegar and potassium iodide as reagents, customers can easily acquire their own reagents from any source (they are also available from Emerson), significantly reducing reagent costs over other total chlorine systems. The reagent only needs to be replaced once every two months. Previous generation systems have required reagent replacement as often as once a week, with best-case scenarios in the region of once per month.
The Model TCL uses either a Model 1055 Solu Comp II chlorine analyser or a Model 54eA analyser. Both analysers are easy to use, provide programmable process alarms, and are housed in rugged NEMA 4X enclosures. The Model 54eA has HART digital communications. The TCL uses the Emerson Model 499ACL-02 amperometric sensor. The sensor is easy to maintain, requiring only a few minutes a month.
The Model TCL total chlorine analysis system is part of Emerson's broad line of Rosemount Analytical instrumentation that powers Emerson's PlantWeb digital plant architecture used by municipalities to keep tabs on a complex water environment. PlantWeb delivers improved plant performance and reduced operating costs by networking the company's broad line of intelligent measurement and analysis devices with Emerson's Ovation expert control system and AMS Suite of predictive maintenance software applications.
The importance of environmental monitoring and visibility at data centres Legrand
Analytical Instrumentation & Environmental Monitoring
Data centres are one of the most energy-intensive building types, consuming up to 50 times the energy per floor space compared to a typical commercial office building. With organisations embracing advanced technologies, data centres powering these technologies are under increasing pressure around the globe to increase capacities and improve efficiencies.

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.
