Benefits at a glance
-
Endress+Hauser supports you with this product bundle for monitoring the remaining organic pollution in the effluent of municipal WWTPs. The Viomax CAS51D SAC sensor ensures optimum process control by monitoring in real time. Chemicals or disposables are not required. The Memosens sensor is ideal for harsh environments and ensures fast data transmission. The Liquiline transmitter's great flexibility in the number of sensors and digital communication makes the measuring point future-proof.
-
Continuous measurement directly in the drain
Thanks to an optical measurement of organic pollution in the wastewater treatment plant outlet with the Viomax CAS51D SAC sensor, you always have the critical values in view. The sensor ensures on-line measurement of SAC254, COD, BOD, TOC or DOC equivalents directly in the outlet.
-
Fast response time and efficient process control
The Viomax CAS51D SAC sensor provides reliable real-time process information thanks to its extremely fast response time and measured value processing in the sensor.
-
Save time and costs and protect the environment
The great advantage of measuring with the optical sensor is that no chemicals or consumables are required; sample preparation is also not necessary. The standardized Memosens technology also enables very simple, time-saving operation and maintenance. The sensor and process-specific data stored in the sensor increase process reliability. An optionally available automatic compressed air cleaning system additionally ensures long maintenance intervals.
-
Ready for automation
The Liquiline CM442 transmitter offers numerous possibilities for automatic measuring operation. For example, cleaning or dosing is possible without a PLC and thanks to the logbook function of the Liquiline transmitter, no separate register is necessary.
-
Modular holder system for open basins and channels
Flexdip CYH112 offers high flexibility for measurements directly where they are needed. It allows almost any sensor mounting such as floor mounting, chain type installation, fixed or free swinging mounting. As the system installs quickly it saves time and costs and it can be expanded or modified at any time.
