Michell Instruments QMA601 process moisture analyser

Click2Contact

The QMA601 process moisture analyser has been updated with an option that makes it suitable for continuous catalyst regeneration (CCR) reforming processes. In CCR reforming, a moisture analyser is a necessary part of the process to ensure that the desired moisture levels remain constant; however, the presence of hydrochloric acid soon compromises sensors, increasing the maintenance cost for the operator.

To prevent the operators from frequent and expensive maintenance Michell engineers developed an updated version of the QMA601 that further extends life of the QCM moisture sensor — making the moisture analyser more cost-efficient in the CCR application. There is also a sample system option that includes a valve isolating the sample from the sensor while allowing a filter drain/bypass flow to continue to purge through the sample line.

Michell’s QMA601 process moisture analyser has a lower detection limit of 0.1 ppmv and an upper range of 2000 ppmv.

The process moisture instruments manufactured by Michell Instruments are easy to install, use and maintain. The QMA601 analyser features a full-colour touchscreen interface which allows interrogation and operation in-situ, with no need for a hot works permit. All data logging and readings are easily visible, and the main display also incorporates real-time trend graphing and alarm indicators.

The analyser is fully certified for use in hazardous areas around the world, with accreditations from ATEX, IECEx and cCSAus.
