Ultra-dry conditions are essential for many petrochemical processes and refineries. The Liquidew moisture in liquid analyzers boosts quality and efficiency through continuous, online measurements of moisture dissolved in a wide variety of non-polar liquids.

The Liquidew moisture in liquid analyzers are based on Michell’s Ceramic Metal-Oxide Moisture Sensor. This versatile moisture sensor is capable of both moisture in gas as well liquid measurements and means that the Liquidew analyzers are eligible for the sensor exchange programme.
The moisture analyzers are designed for flammable and non-flammable liquid within hazardous areas. They carry global hazardous area certification from IECEx, ATEX, UKCA, cQPSus, TR CU and GOST. Full details of the certifications for each product are in the downloads section of each product page and on the datasheet.
Sample conditioning is essential for getting the best accuracy for moisture measurements in hydrocarbon liquids. Michell offer fully enclosed or panel-mounted sampling systems which feature flow control and particulate filtration.
The analyzers measure the moisture content in ppmW.
These analyzers measure moisture in non-polar liquids like naphtha, diesel, and aviation fuels.
To accurately measure the moisture content, saturation constants need to be available for each hydrocarbon in the composition. Each hydrocarbon has unique saturation constants that stipulate how much moisture it can dissolve at a certain temperature. The ppmW result is calculated from the sensor reading and these constants so using the incorrect constants or not having constants will create an incorrect measurement. To check if a measurement is possible in your hydrocarbon liquid, please contact us and you will be put in touch with your local sales representative or distributor.
Yes, the sensors should be calibrated on a regular basis to ensure consistent quality and operational efficiency.
An alternative option is our sensor exchange program. A newly calibrated, refurbished transmitter is swapped with your existing one, which is then shipped back to our factory. The advantage of this is that there is no measurement downtime compared to shipping sensors off for recalibration.Due to the range of the saturation constants, the sample must be between 0 and 50°C when it reaches the sensor. Sampling systems including cooling/heating coils can be designed to guarantee the sample temperature falls within this range.
