Operating Principles

Almost all measuring instruments for suspended solid substances are based on a method of processing the attenuation amount of ultrasonic waves through comparison of amplitude variations of the wave receiving signal. When this method is used, the capacity of solid substances in a liquid is kept fixed. Because the pipe shape and flow velocity affect the stability and reliability of measurement, high-precision measurement is impossible. Our KWS200 type meter increases precision by method of calculating energy with the wave receiving envelope, not by utilizing amplitude variations of the wave receiving signal.
