• Arenal - Process Control & Monitoring Solutions
 

Applications

Although the ceramic ultrasonic and thermal sensors of Arenal PCS can be applied in any liquid in the world, it is mainly designed for abrasive slurries and pastes, which can be found in Mineral and Metal processing plants, dredging and tunneling. Arenal is actively involved in industrial slurries, like in CMP, pigment and catalysts slurries and battery pastes and potato starch slurries.


The optimal slurry for measuring density, flow and massflow is a homogene turbulent slurry in a pipe or vessel, with a large concentration of particles below 1 mm.

Phosphoric acid Analyser (H3PO4)

Arenal PCS produces H3PO4 concentration Analysers for the chemical industry, based on ultrasonic spectroscopy. The phosphoric acid Analyser consists of the process control Analyser, the ultrasonic transmitter and an ultrasonic sensor. Depending on the application, the sensor can be mounted in the process or in an extractive system.

 

Some points of use in the industry

    • Production rust inhibitor
    • Food additive
    • Etchant
    • Fertilizer
    • Home cleaning

 

Technology

Ultrasonic spectroscopy is mainly used for applications in which high accuracy is required. High energy pulses are induced into the piezo element: an ultrasonic wave arises and propagates through the probe: the reflections from the the interface between the element and the liquid, as well as the reflected echo in the liquid are measured. Their properties change due to the temperature and the properties of the liquid. All acoustic properties are calculated in the process control Analyser (PCA). In the PCA the density, SG, concentration and temperature are calculated. Learn more about the technology here.

 

Embodiments

The preferred embodyment is extractive in QB blocks. A small sample volume is pumped through the teflon blocks.
