Disinfection measurement systems
Free or total chlorine measurement systems eliminate reagents with amperometric sensor technology
Each disinfection measurement system is designed to provide a turnkey panel-mounted solution for free or total chlorine measurement. Each incorporates a Memosens amperometric chlorine sensor. Free chlorine systems include a Memosens pH probe for accurate and reliable hypochlorous acid disinfection measurement. Each panel is equipped with a Liquiline transmitter, either a model CM442 or CM444. Systems are also available with EtherNet/IP digital communications with the model CM444 transmitter.
Benefits
EPA compliant according to Method 334.0 for free chlorine
Reagent-less systems using amperometric sensor technology
Easy DPD testing with built-in test valve and pH compensated measurement ensures accurate DPD verification
Inlet and outlet valves allow isolation for routine sensor maintenance
System design
A disinfection panel system is comprised of a Liquiline transmitter, either the CM442 or CM444 and an amperometric chlorine sensor, either free or total. The chlorine sensor mounts in the integral flow assembly (Flowfit CCA250), and with free chlorine systems a pH sensor is also included to install in the flow assembly. All panels include pressure regulation and an integral flow switch mounted in the flow assembly to monitor for proper sample flow rate.
Enclosure rating
The transmitter has a NEMA 4X (IP66) rating and all other components are water-proof, for installation indoors, outdoors or in an enclosure.
Integrated flow assembly and pressure regulation
Integrated flow cell is designed to properly hold both the chlorine and pH probes
Built in needle valve for flow control between 30 and 120 L/hr
Inductive low flow alarm switch indicates when flow is too low for proper measurement
Pressure regulator to maintain constant measurement conditions
Liquiline and Memosens® technology
Memosens sensors eliminate problems associated with analog sensor technology
Liquiline transmitter in two or four channel version with a range of I/O simplifies control system integration
Optional Memobase Plus hardware and software enables intelligent sensor management
