PIOX® S - Concentration and Mass Flow Measurement by Ultrasound​

PIOX® S is primarily used for the concentration analysis during process control, the dosing of chemicals or for overall quality control. Further applications are the supervision of crystallization or phase separation processes for a proper product identification. Alternatively, density, yield rate, Brix or other customer specific measurement values can be displayed.


Combining these features with the integrated volumetric flow measurement , the PIOX S system is capable of calculating the (concentration compensated) mass flow rate. 

PIOX® R Inline Process Refractometer - Chemical Design Variant

The concentration analysis of liquid media is one of the most critical parameters for aproper process and quality control within the Chemical Industry.

By measuring the refractive index, concentration levels of many media consumed or created within the chemical and textile fiber industry, such as solvents, acids, caustics as well as other - often corrosive and toxic - intermediate and end products, can accurately be monitored and a total quality control be assured.

Both designs are highly durable against any corrosive and toxic media due to theirinternal FFKM gaskets, the media and scratch resistant sapphire optics as well as the complete separation of the sensor head from the electronics compartment.

For measuring toxic and corrosive organic as well as anorganic media, PIOX® R is offered as a fully stainless steel design variant with all wetted materials made out of grade 316 Ti / 1.4571 steel.

When dealing with highly corrosive media, such as hydrochloric, strong sulfuric or hydroflouric acid, PIOX® R is also available as a special carbon fibre reinforced PTFE design variant offering an unrivalled corrosion resistance, long term stability and reliability in such harsh environments.

Being ATEX Zone 0/1, 1 and 2 certified and available with long and short sensor heads that can be integrated into the process via DIN / ANSI compatible flange or the proprietary FLEXIM flow cell, PIOX® R is the ideal process analytical technology for a wide array of liquid media within the chemical industry.

FLUXUS HPI Series Flow Meter

By combining the attributes of FLEXIM’s highly accurate and reliable non-intrusive ultrasonic flow measurement with temperature and, where necessary, pressure inputs, the integrated HPI flow meter is the ideal solution for hydrocarbon flow metering applications, where the fluid viscosity can significantly vary over the temperature range.


The internal HPI flow computer allows the meter to report:

  • Operational and standard (net) volume and mass flow

  • Density, API number and Specific Gravity

  • Sonic ID (for Interface Detection)

  • Liquid ID (for Fluid Identification)

  • Leak detection (data source based on multiple HPI flow meters)


FLEXIM’s HPI flow meter eliminates measurement errors associated with multiple devices at various places and provides a complete turn-key solution to your flow metering needs.
