FIELD: agriculture, mechanical engineering. SUBSTANCE: electrode system of transducer is connected to input of generator retunable frequency. Outputs of given generator and reference frequency generator are coupled to proper inputs of third counter by means of corresponding counters across which output code corresponding to number proportional to value of level of liquid in vessel is set. Further code is converted to current signal with the aid of digital-to-analog converter and is recorded by indicator. EFFECT: expanded application field, improved authenticity of test of level of liquid. 3 cl, 2 dwg
