In applications where chlorine and chlorine dioxide are used to disinfect water in water supply systems, industrial processes and swimming pools, accurate measurement is of utmost importance if the correct balance between the sterility of the water and its safety is to be maintained. It is for this reason that Endress+Hauser Liquisys S analysis transmitter, (known for its flexibility and ease-of-use in the measurement of pH, conductivity, dissolved oxygen, turbidity and residual chlorine) has been extended to include the Liquisys S Chlorine version. The development of this new measuring transmitter specifically for measuring free chlorine and chlorine dioxide was completed last year, and internal beta-tests have been running in a public indoor pool (chlorine) and a water work (chlorine dioxide) for several weeks.
All three versions of this new measuring transmitter - the basic EK version, which can be used for measurement of chlorine and chlorine dioxide, the plus package ES version with added features - and the full expansion EP version, which offers a combined measurement with pH or ORP in one instrument - are modular in design. This means they are highly adaptable to a wide range of customer needs. The basic version, which provides simple measuring and alarm signalling functions, can be equipped with additional software and hardware modules to meet specific applications. Expansion modules can be retrofitted as required.
The chlorine unit has a number of new features, which contribute toward a significant increase in technical performance at a reduced price. It is compatible with all sensors - CCS 140/141 for free chlorine and CCS240/241 for chlorine dioxide - as well as with the new open sensor 963 in the EK version. The EP version offers additional pH value or redox potential in an instrument. This expansion stage also allows control of the pH value process. pH compensation for free chlorine is available to both the automatic and manual mode.
As these sensors are zero-current-free, they require only a single-point calibration. Unnecessary claims can be suppressed thanks to the unit's ability for independent configuration of the alarm contact and the error current.
The 4 to 20mA current input for mainstream flow monitoring has an automatic dosing stop facilitated by a free selectable limit value. The PID controller outputs are also influenced by the mainstream flow to facilitate short response control loops in the water industry. The bypass flow monitoring via inductive proximity switch INS with automatic dosing stop is also available. Each check function is selectable with or without additional dosing stop. The PID controller for chlorine/chlorine dioxide now includes a controller for pH, as well as a three-point step controller for chlorine/chlorine dioxide.
