The Liquisys COM223 standard
transmitter can be used in conjunction with the dissolved oxygen measuring
sensors COS41 and COS61. Improve operational safety through continuous rationality testing and process and
sensor testing. Choose from numerous hardware and software modules (such as relays and bus communication) to meet the needs of measurement tasks. It also allows the
transmitter to be upgraded at any time. The simple menu and calibration make the instrument setup and operation convenient and quick.
Advantage
Higher operational safety: continuous process inspection system, customized alarm settings, calibration authenticity check
Reliable dissolved oxygen control: current input is used for flow rate monitoring and feedforward control with
controller shutdown
Simple operation and maintenance: simple one-point calibration in air, oxygen-saturated water or medium, direct manual touch control
Reduce maintenance: trigger automatic cleaning function by alarm or limit switch (using Chemoclean)
Suitable for various applications: multiple extended functions, such as P(ID)
controller, timer, etc., can be flexibly applied to various processes
