Abstract
- The article deals with the construction of intelligent flow meters, in which primary detector, sensors, analog-to-digital converters, and microprocessors for solving the problem of distribution of functions between the elements of measurement, conversion and calculation systems are integrated. The flow meter contains a jet generator, which is an acoustic multivibrator. Jet generator converts the flow rate into acoustic vibrations, which are converted into a polyharmonic electrical by piezoelectric transducer. An adaptive line enhancer contains an electronically controlled filter on the varicap and allocates an informative first harmonic and functionally processes it in accordance with the analytical expression of the flow rate from the frequency. The microprocessor processes all information from the adaptive line enhancer and measurement channels from the inert gas concentration sensors, which are impedance biological sensors, and from the integral temperature sensor. The measurement results are displayed on the flow meter display and transmitted via digital communication channels to the dispatcher console.
