Concentration measurement of liquids..
By means of a special probe immersed into the liquid the ECHOMETER 1076 K determines the sound velocity of the liquid, which is a measure of the substance concentration.
Measuring principle of the ECHOMETER 1076 K:
The ECHOMETER 1076 K is an instrument to measure the sound velocity of liquids.
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.
