The Rhosonics product range is highly versatile and ideal for a variety of applications in the chemical industry. Moreover, the devices can be custom-made from any material to ensure resistance to the liquid being measured. Because Rhosonics sensors boast high accuracy, they can be used to measure various parameters such as liquid concentration, TDS (Total Dissolved Solids), or TSS (Total Suspended Solids). Furthermore, Rhosonics sensors are highly versatile and can aid in the measurement of main processes, clear liquids, cloudy liquids, and slurries. After all, Rhosonics offers a comprehensive and effective solution for all your liquid measurement needs in the chemical industry.

Acid and base solutions

Rhosonics has been providing ultrasonic chemical concentration sensors professionally for over two decades and, meanwhile, has developed various acid and base measurement applications for organizations around the world. Acid and base solutions prove to be a great challenge for companies.

Through providing solutions to these challenges for decades, Rhosonics has acquired significant and unparalleled expertise in this industry and can provide you with the right instrumentation and personnel to increase your company’s efficiency.

Common chemicals that require measurement are:

  • Maleic acid
  • H2S04/Fuming Sulfuric acid
  • Citric acid
  • Hydrofluoric acid (HF)
  • HBR
  • Hydrochloric acid
  • Silanes
  • Boric acid
Salts and other chemicals

Ultrasound technology enables the measurement of salts and other chemicals, like alcohols, added to liquids such as water. Salt is a substance produced by the reaction of an acid with a base. The concentration of salt in water has an effect on the velocity with which sounds travel through the liquid. By measuring the speed of sound, even lower concentrations can be precisely measured.

Some of the most popular applications can be seen below. These applications include chemicals such as alcohols (Ethanol, Methanol, Isopropyl alcohol, etc.).

  • Hydrogen peroxide
  • Sodium Sulfate
  • Potassium hydroxide
  • Sodium Chloride
  • Potassium carbonate
  • ITO etchant
  • Sodium Hydroxide
  • Ammonium Fluoride
  • Potash etc.
The manufacturing of fine chemicals involves many small and complex steps. E.g., understanding the complexities of chemosynthesis, biotechnology, extraction and hydrolysis. Therefore, Rhosonics offers products to measure this type of fine chemical using ultrasonic technology to check various parameters such as liquid concentration, temperature, solids and density.


Surfactants are chemical compounds that reduce the surface tension between two liquids, between a gas and a liquid, or between a liquid and a solid. Also, they act as detergents, wetting agents, emulsifiers, swelling agents, or dispersing agents and are an important building block in many other applications and industries. Therefore, Rhosonics ultrasonic sensor products assist organizations in measuring the concentration of liquids and minerals with precise accuracy, enabling them to strive to newer heights.
