            The Sonatec ultrasonic concentration sensor and transmitter is ideally suited for quantitative process monitoring and control in beverage, brewing, pharmaceutical chemical and related industries.  It is especially useful in processes where the proportions of two ingredients need to be measured accurately, when for example blending two liquids

            The Sonatec Ultrasonic Concentration Sensor is a highly precise means of determining the sound velocity through liquids. Like density measurements, sound velocity is a material and concentration dependent quantity which can be used for determining the concentration of a liquid. The propagation time of a piezo-ceramic generated sound pulse is measured between the prongs of a fork-shaped measuring head installed directly in the process. As this propagation time changes, the sound velocity and resulting concentration changes are measured. The temperature dependence of the sound velocity measurement is compensated through the electronic measurement of parallel PT1000 temperature elements. From these measurement signals, calculated concentrations are obtained and displayed in Mass%, Volume%, °Brix, %Extract or other sound velocity calculable quantities of the measured medium. Due to the simple mechanical design without any movable parts, the sensor is very reliable and virtually maintenance free. The use of this technology with specific measurement software has a proven track record for liquids with dissolved and un-dissolved components, both organic and inorganic.
