The Liquisys CCM253 is a standard free chlorine measuring transmitter and can also measure pH for compensation of the free chlorine measurement. Continuous plausibility, measuring process and sensor checks increase operational safety. Regardless of the choice from a wide range of hardware and software modules, such as relays and bus communication, it adapts fully to the measuring task. The transmitter can also be upgraded at any time; its simple menus and factory calibration make configuration and operation quick and convenient.
Advantages
Higher operational safety: continuous process check system, user-defined alarm settings, calibration plausibility check
Reliable chlorine and pH control: current input for flow monitoring with controller switch-off and feedforward control
Convenient operation and service: intuitive user interface, simple chlorine and pH calibration, manual contact control
Reduced maintenance workload: automatic cleaning function triggered by alarm and limit switches (with Chemoclean)
Suitable for various applications: multiple expansion options such as P(ID) controller, timer, etc., suitable for all processes
