Liquid Analysis
Fluid analysis plays a key role in monitoring and optimising processes in many different industries. By analysing the properties and composition of fluids, our solutions help ensure high product quality, efficient operations and regulatory compliance. Whether optimising production, ensuring safety or meeting stringent environmental requirements, our instruments and systems offer the precision and reliability needed to achieve the best possible results.
More information
What is liquid analysis?
Fluid analysis is the collective name for chemical, physical and/or microbiological methods used to determine the composition and properties of a fluid. The technology is used in industries ranging from process and pulp & paper to water and wastewater treatment, food, energy and HVAC systems.
Common measurement parameters for liquid analyses
Some typical quantities analysed are:
| Parameter | Example of use | Typical sensor/device |
| pH/Redox | Process and environmental monitoring | pH/ORP electrode/transmitter |
| Conductivity | Drinking water,Wastewater treatment plants, CIP processes, concentration determination | 2 or 4 pole electrode, inductive conductivity sensor |
| Turbidity/mud content | Drinking water, process water, breweries | Optical turbidity sensor |
| Dissolved oxygen | Bioprocess, aquaculture | Optical oxygen sensor |
| Free chlorine/ozone | Disinfection of water | Chlorine analyser, photometry |
| Viscosity/density | Oils, chemical fluids, food and liquids | Viscometer |
| temperature | Process and environmental monitoring | Pt100 sensor or thermocouple |
| Refractive index | Concentration measurement, Brix | Refractometer |
| Photometry | Concentration / Colour measurement, product identification | Photometers |
| Oil in water / Oil on water | Environmental monitoring, leak detection | UV Fluorescence / Photometry |
| Sodium / Silicon | Boiler water, steam cycle | Online analyser |
