Product Overview
CM Aquatechnik supplies a comprehensive range of online process analysers and sensors for water quality monitoring and process control in water treatment, wastewater treatment, and industrial process applications. Our instrumentation programme covers: pH/ORP, dissolved oxygen (DO), turbidity/TSS, conductivity/TDS, free chlorine/chloramine, TOC, flow (electromagnetic, ultrasonic, venturi), level (ultrasonic, pressure), and pressure transmitters.
All instruments are available with 4–20 mA, HART, Profibus, Modbus, and FOUNDATION Fieldbus outputs for seamless integration with Siemens, Allen-Bradley, and all major SCADA systems.
Frequently asked questions
Which parameters can be measured online?
Our programme covers pH/ORP, dissolved oxygen, turbidity/TSS, conductivity/TDS, free chlorine/chloramine and TOC, together with flow, level and pressure transmitters. The right combination depends on the process stage, for example DO and ORP in biological treatment or conductivity for RO permeate monitoring.
How do the instruments integrate with my PLC or SCADA system?
All instruments are available with 4–20 mA, HART, Profibus, Modbus and FOUNDATION Fieldbus outputs. This allows seamless integration with Siemens, Allen-Bradley and all major SCADA and DCS systems.
How much maintenance do online analysers require?
Automatic self-cleaning sensor systems reduce routine maintenance to less than 30 minutes per month, and most analysers offer automatic in-situ calibration. Heartbeat Technology additionally provides continuous self-verification without interrupting the process.
What information do you need for a quotation?
Please provide the parameters and measuring ranges required, the medium with its temperature and pressure, the mounting location (pipe, open channel or tank), the required output signal or fieldbus, the available power supply and any hazardous area (ATEX) or SIL requirements. Send us your requirements and we will prepare a proposal within 48 hours.
