FIELD: physics.
SUBSTANCE: invention relates to an ultrasonic flow meter with a mini-support structure. Monolithic matching structure for use in an ultrasonic transducer includes a mini-support grid. Mini-bearing grid includes rear plate, multiple horns and front plate. Plurality of horns extend from rear plate. Each of the horns includes a base and a neck. Base adjoins rear plate. Neck passes from the base. Area of base cross-section exceeds cross-section area of neck. Front plate adjoins the mouth of each of the horns.
EFFECT: technical result is possibility of measuring fluid flow in media with extreme temperatures.
