Mass Measurement


Concentration and mass flow measurement

August 2014 Mass Measurement

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

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

Clamp-on technology for ease of use

The measuring system, composed of a transmitter and a pair of clamp-on transducers, precisely determines the sonic velocity of the medium based upon the ultrasonic transit-time measured between the two transducers. The clamp-on transducers are mounted on the outer surface of the pipe, and as they are not in contact with the medium, the system is ideally suited for the measurement of chemically aggressive, corrosive, abrasive or ultra-pure media.

Piox S can be used to determine the concentration of high purity sulphuric acid, hydrofluoric acid, nitric acid or even ammonia gas used in fertiliser plants. Worries about the transducers chemical compatibility, contamination and sealing are a thing of the past.

With the clamp-on technology, retrofitting of existing installations is easy and can be done without cutting into the pipe or interrupting the process. The non-intrusive acoustical technique is also the method of choice when the materials and processes place high demands on safety and purity. The system is thus well suited for the food and beverage industry with its high sanitary standards. Here, it is used to measure the alcohol or sugar content in liquids and is a proven method for CIP process optimisation.
