Research on high-precision compensation algorithm for ultrasonic thermal energy flowmeter with time difference method

  • Received Date: 2020-12-14
  • Aiming at the problems of the insufficient sensitivity and poor measurement accuracy due to the stable flow rate and rate changes and other factors, taking ultrasonic thermal energy flowmeter with time difference method as the research object, an adaptive compensation algorithm for thermal energy flowmeter was proposed. The nonlinear relationship between heat and comprehensive compensation coefficient was studied, a mathematical model of error compensation was established, and then a weighted Lagrange fitting correction algorithm was proposed to realize adaptive correction of comprehensive coefficients. The experimental results showed that, compared with the traditional algorithms, the proposed algorithm could improve the instrument detection accuracy and reduce the measurement error which had high engineering application value.
