- Product Description
-
- Commodity name: Rosemount Flexim PIOX S831 Non-Invasive Ultrasonic Liquid Analyzer
- Commodity ID: Flexim-Piox-S831
The Flexim PIOX S831 Liquid Analyzer is certified for operation in hazardous areas (ATEX/ICEx Zone 1, FM Class I Groups 1+2). It determines liquid concentration and density using an external clamp-on ultrasonic sensor installed on the outer side of the pipeline. Non-invasive technology is the preferred system when safety and reliability requirements for substances and processes are particularly stringent. The PIOX S utilizes dynamic inference based on sound velocity and temperature measurements to accurately calculate fluid density. For binary liquids such as acids or carbonated beverages, sound velocity maintains a fixed relationship with both concentration and density. Additionally, this flowmeter employs the time-of-flight differential method to measure volumetric flow rate, enabling it to determine mass flow rates for liquids of varying densities.
