FIELD: measuring equipment.
SUBSTANCE: invention relates to a flow meter. Flow meter has installed on pipeline, through which fluid flows, measuring channel (14), on which measuring unit is fixed, having at least two ultrasonic sensors (28, 30) located at a distance from each other, wherein input and output of measuring signals into fluid medium or respectively from it is carried out through corresponding connecting element (32, 34), which contains said sensors (28, 30), wherein connecting element (32, 34) is inserted flush in circumferential wall of measuring channel (14), so that it does not protrude into measuring channel, wherein connecting elements (32, 34) have connecting wedge (48, 50), which is inclined to axis of measuring channel, on which sensors (28, 30) are resting. At that on located in pairs on the side of input and output connecting elements (32, 34) there is one double sensor (28a, 28b, 30a, 30b) or a pair of separate sensors (28a, 28b, 30a, 30b), so that at least two approximately parallel signal paths (128a, 128b) are formed between pairwise located connecting elements (32, 34), note here that reflector (52) is arranged in sensor transverse wall (40) to be flush with crosswise wall pocket (78).
EFFECT: technical result is the increased accuracy of measurements.
