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