Algorithms on improvement of accuracy of biofuel temperature measurement in thermo-anemometric flowmeter

This article considers the errors of biofuel temperature measurement based on the use of thermoelectric converter in thermo-anemometric flowmeter. Quantitatively, these measurement errors are represented by a mathematical model. Therefore, for greater efficiency of using the thermal converters, the required calculations of TAF errors were made, and an analysis of feasibility of using this TAF was carried out. The study findings established the measurement accuracy and speed of response ensuring a continuous process of measurements in real time. A new mathematical model of thermo-anemometric flowmeter errors was developed and analytical expressions for calculation of its basic errors was obtained. The use of a set of thermal methods and creation of new flowmeters designs allow measuring the flow of biofuels in a fully automated way, with high precision and speed.
