FLOW METER OF THE WORKING MEDIUM WITH A JET VIBRATION CONVERTER INTO AN ELECTRICAL SIGNAL Russian patent published in 2022 - IPC G01F1/20 

FIELD: instrumentation.

SUBSTANCE: invention relates to the field of instrumentation and can be used in gas turbine engine control systems. The flow meter contains a housing with inlet and outlet fittings, inside which an oscillator with jet elements is placed, made in the form of stacked plates, and a converter of jet vibrations into an electrical signal, consisting of a container with a piezo sensor forming an electrical signal about the actual flow of the working medium, the control cavities of the piezo sensor are connected by mains to the feedback channels of the jet generator, structurally identical spray nozzles are installed in the mains, the mains are made of the same length and width, have the same number of turns at the same angle.

EFFECT: increased noise immunity and accuracy of the flow meter by eliminating the influence of pressure pulsations of the measured medium at the inlet to the flow meter on the operation of the piezo sensor.
