In the fields of aviation and space technology, the study of high-speed gas-liquid flows is relevant because there is a lack of precise measuring devices, and the measuring range of speed and pulsation possible with available devices is insufficient. Authors offer a solution that extends the capabilities of the LDMS devices. This paper proposes a new structure of the LDMS processing module made on the base of modern high-efficiency 6-core signal processor TMS320C6472 and high-speed ADC ADS62P49 with sampling rate up to 250 MHz signals. This new processing module and attached software enable the LDMS to calculate the gas-liquid flows speed at a rate of up to 100 kHz / sec. On the basis of this structure it’s possible to create a LDMS that enables high-precision measurement of gas-liquid flows rates of up to 3000 km/h, and pulsation with frequencies up to 50 kHz.
