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
