Memosens Wave CKI50 process spectrometer
-
Memosens Wave spectrometer for color measurement in the food and beverage, chemical and life sciences industries
Advantages
-
Compact design: the color of the entire spectrum can be determined with just one device.
-
Easy commissioning: with Memosens technology and Liquiline transmitters, installation is fast and simple. No calibration required, only the reference spectrum of the zero point needs to be recorded.
-
Powerful color measurement: highly repeatable and long-term reliable color measurement even in demanding process environments, thanks to its high resistance to water ingress, vibration and high temperatures.
-
Safe and efficient process control: the hygienic design ensures safe product production. By checking the color directly in the process, product losses and potential health risks to consumers can be prevented
Field of application
-
The Memosens Wave CKI50 is compactly designed and the spectrometer provides reliable, fast color control directly in the process. At the same time, the process spectrometer ensures that hygiene and material standards comply with the specifications of the food industry. Thanks to preset color models and connection to Liquiline transmitters, commissioning is very simple and measurement is stable.
-
Quality control: color deviations in the final product are caused by color changes in the raw materials. It is therefore crucial to identify them and initiate appropriate adjustments
-
Filling control: the increasing product diversity and higher production speeds bring the risk of incorrect bottling. Reliable and fast color detection is crucial.
-
Phase control: via color detection, the phase state in pipes can be quickly identified and product losses minimized, for example during product changeover or cleaning processes.

Municipal Wastewater Treatment · turbidity — Application Case
Project Background
The project covers the inlet, biological and outlet stages of a municipal plant. The work centres on turbidity and the core task is measuring turbidity as an indicator of suspended solids and filtration.
Operating Challenges
The medium and duty are characterised by high solids and corrosive fractions, with large diurnal flow swings, and effluent parameters drift and probes foul with sludge and biofilm. So turbidity cannot be specified generically — it calls for choosing 90° scatter or surface scatter by range, with de-bubbling.
Solution
The Ainstru engineering team worked through the analyser range: selecting as part of a complete water-analysis system. The configuration involves choosing 90° scatter or surface scatter by range, with de-bubbling, with these requirements in view: stable compliance with Grade 1A discharge limits and online data reporting.
Results
Since start-up the system has run steadily; the practical result is backwashing triggered by water quality, saving water while holding quality.
Food & Beverage · turbidity — Application Case
Project Overview
The site is dosing, pasteurising, filling and CIP stages. The customer wanted turbidity properly configured on the existing plant, with the aim of measuring turbidity as an indicator of suspended solids and filtration.
Technical Challenges
What actually causes trouble is syrups, dairy and beverages that scale easily, under strict hygienic requirements, and frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles. All of this means the turbidity configuration has to involve choosing 90° scatter or surface scatter by range, with de-bubbling.
Configuration
Supply and installation were organised through the analyser range: selecting as part of a complete water-analysis system. On site this meant choosing 90° scatter or surface scatter by range, with de-bubbling, checked line by line against: food-safety and hygienic design per 3-A / EHEDG.
Performance
After commissioning the outcome is backwashing triggered by water quality, saving water while holding quality, and the readings are now used for process tuning.
Chemical & Pharmaceutical · turbidity — Application Case
Site Conditions
This is a Chemical & Pharmaceutical customer whose plant is at reactors, metering vessels and finished-product tanks. The main task was measuring turbidity as an indicator of suspended solids and filtration.
The Problem
The difficulty lies in highly corrosive media with solvents and crystallisation, partly in explosive atmospheres; at the same time corrosion plus Ex protection shortens instrument life and makes downtime costly. Specification therefore means choosing 90° scatter or surface scatter by range, with de-bubbling.
What We Did
We took a analyser range approach — selecting as part of a complete water-analysis system. Delivery was built around choosing 90° scatter or surface scatter by range, with de-bubbling, with point-by-point checks on: Ex certification and GMP traceability of records.
Operating Outcome
In service the system performs as intended — backwashing triggered by water quality, saving water while holding quality, with routine maintenance falling noticeably.
Power & Energy · turbidity — Application Case
Application Context
boiler feedwater, turbine condensate and FGD/DeNOx systems is a typical Power & Energy duty. The project started from turbidity, focusing on measuring turbidity as an indicator of suspended solids and filtration.
Process Constraints
drift under high temperature and pressure, with very costly unplanned outages, and high temperature and pressure with both steam and saline water only amplify it. The turbidity specification must therefore cover choosing 90° scatter or surface scatter by range, with de-bubbling.
Delivery Approach
Delivery was handled as the analyser range — selecting as part of a complete water-analysis system. Execution centred on choosing 90° scatter or surface scatter by range, with de-bubbling, together with compliance with power-industry codes and unit availability targets.
Field Results
Operation shows the benefit clearly — backwashing triggered by water quality, saving water while holding quality, with confidence in this measuring point improving markedly.
