Field of application

Liquisys CLM253 is a standard transmitter for all analog conductivity sensors. It improves your operational safety thanks to continuous plausibility, process and sensor checks. Select from numerous hardware and software modules, such as relays or fieldbus communication, to adapt it exactly to your measuring task. This modularity also allows you to upgrade the transmitter at any time. A simple menu and calibration make configuration and operation fast and easy.

The Liquisys CLM253 transmitter works with all analog conductivity sensors in non-hazardous areas, for example in these industries and their utilities:

  • Chemicals

  • Food & Beverages

  • Life Sciences

  • Power & Energy

  • Water &Wastewater

  • Primaries & Metal

Liquisys CLM253 features the following protocols and interfaces:

  • 0/4...20 mA

  • HART

  • PROFIBUS DP

  • PROFIBUS PA

Benefits

  • More operational safety: Continuous process check system, customized alarm configuration, calibration plausibility check.

  • Broad functionality: Conductivity, resistivity and concentration measurement, ultrapure water monitoring according to USP and EP.

  • Easy to operate and service: Intuitive user interface, easy calibration, direct access for manual contact control.

  • Reduced maintenance: Automatic cleaning function (with Chemoclean) triggered by alarm or limit switch.

  • Fit for every application: Numerous extensions, such as P(ID) controller, timer, etc., allow for flexible adaption to all processes.

Success stories

  • Picture of Teqwave T – Ultrasonic concentration meter Picture of Teqwave T – Ultrasonic concentration meter

    Measurable and testable: Monitoring with Teqwave

    Efficient component cleaning is an important part of the production of industrially manufactured components. Borer Chemie AG therefore relies on the concentration measurement with Teqwave F, I and T.

  • Detection of SARS Cov-2 virus in wastewater to make reliable predictions Detection of SARS Cov-2 virus in wastewater to make reliable predictions

    Monitoring biological parameters in wastewater

    Examination of wastewater, using the Liquistation CSF48 and the Liquiport CSP48 mobile, can provide valuable information about the occurrence of Covid 19 infections in a specific area

  • ICUMSA scheme ICUMSA scheme

    High-quality sugar and no bittersweet surprise

    To protect consumers, high quality standards apply in the food industry. Sugar quality must be measured by ICUMSA. This measurement is expensive and time consuming. With the OUSAF22 color sensor it is possible to measure the ICUMSA color value.

  • Wastewater treatment and TOC measurement Wastewater treatment and TOC measurement

    TOCeq measurement in wastewater treatment

    TOC measurements are often performed using analyzers that require expensive reagents. The CAS51D enables the plant operators to comply with WHO requirements and guarantees tight measurement intervals.

  • Minera Valle Central in Chile performs online interface measurement and turbidity monitoring Minera Valle Central in Chile performs online interface measurement and turbidity monitoring

    Improved thickener operation at Minera Valle Central

    The measurement of interface in thickeners is done manually, while the turbidity measurement is done by obtaining samples sent to the laboratory. With Endress+Hauser there is an automated solution.
