ULTRASONIC FLOWMETER Russian patent published in 2020 - IPC G01F1/66 

FIELD: machine building.

SUBSTANCE: invention relates to an ultrasonic flow meter having a pipeline in a support housing and at least two ultrasonic transducers provided in a measuring insert which can be inserted into the support housing and into the pipeline perpendicular to the pipeline. Pipeline comprises round cylindrical seat with diameter larger than tube inner diameter and depth enclosing tube inner part to insert measuring insert in pipeline perpendicular to flow direction. Four ultrasonic transducers are located in the wall of the measuring insert, converters form at least two measurement paths, wherein said measurement paths intersect with each other in a top view, and the transducers are located in the wall of the measuring insert such that during operation the ultrasonic signals emitted and received by the ultrasonic transducers on the measurement paths have a transit time difference t_h-t_r, which depends on the flow rate v and/or flow rate Q of the fluid flowing in pipeline.

EFFECT: technical result is creation of ultrasonic flowmeter, which requires small mounting space and nevertheless is intended for high pressures and is suitable for industrial standard and easy production.
