Concentration meter
ECHOMETER 1076 K
KARL DEUTSCH
The accompanying probe is designed like a cuvette and simply gets dipped into the liquid for measurement.
Each an ultrasound transmitter and a receiver are included in the probe. Their piezo elements are covered by a protective layer to prevent damage by chemically aggressive liquids to be measured.
Subject of measurement is the time that is required for the sound to run through a constant, defined path between transmitter and receiver being submerged in the liquid.
Then the sound velocity becomes calculated by the electronic evaluation unit and is shown on the display of the gauge.
