Embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with schematic diagram the technical solution of the utility model being introduced further and illustrating, but being not limited to this.
As shown in Figure 1, a kind of ultrasonic current metre 1, for measuring the flow velocity of liquid.Ultrasonic current metre 1 comprises: current meter body 2, is installed on the ultrasonic reflections end 3 of velocity measurement instrument body 2 side, and is installed on current meter body 2 and is positioned at ultrasound wave transmitting terminal 4, the ultrasound wave receiving end 5 of ultrasonic reflections end opposite side.
Current meter body 2 is provided with symmetrical V-arrangement passage 21, and V-arrangement passage 21 comprises first passage 211, second channel 212.The cross sectional shape of first passage 211, second channel 212 is circular.First passage 211 is provided with the first mounting hole 22 with the end that crosses of second channel 212, and ultrasonic reflections end 3 is fixed and is sealed in the first mounting hole 22, ensure that liquid stream can not flow out when ultrasonic reflections end 3.
Ultrasound wave transmitting terminal 4 is installed on the end of first passage 211, and the end of first passage 211 is provided with the second mounting hole 23, and ultrasound wave transmitting terminal 4 is sealingly fastened in the second mounting hole 23; Ultrasound wave receiving end 5 is installed on the end of second channel 212, and the end of second channel 212 is provided with the 3rd mounting hole 24, and ultrasound wave receiving end 5 is sealingly fastened in the 3rd mounting hole 24, and the liquid flowing through V-arrangement passage 21 can not flow to the external world.Ultrasound wave transmitting terminal 4, ultrasound wave receiving end 5 are symmetrical in ultrasonic reflections end 3 and arrange, after making ultrasound wave reach ultrasonic reflections end 3, and can with the angle of reflection identical with incident angle to ultrasound wave receiving end 5.
