Measure on line Concentration with Sonic Velocity

MEASURING PRINCIPLE:

Ultrasound can be used for measuring inline concentration in cases where density measurements fail to yield the desired results. Unlike direct density measurement, ultrasonic measuring devices offer the advantage that measurements may be performed directly in the vessel.

The sonic velocity sensor measures concentration in an inline process liquid stream. The delay time of the sonic pulse is measured over a constant distance between the transmitter and receiver. The relationship between sonic velocity, temperature, and concentration for different fluids is mathematically stored in the controller's software and is used to present the correct fluid concentration. Ultra sonic sensors measure inline concentration of liquids, crystallization and neutralization, beer, wort, and many other processes with sound velocity technology.
