The invention provides a water meter measurement tube and an ultrasonic water meter. The water meter measurement tube comprises a reflector assembly, a measurement tube section, a first transducer installation tube section for installing a first ultrasonic transducer, and a second transducer installation tube section for installing a second ultrasonic transducer, wherein the first transducer installation tube section and the second transducer installation tube section are arranged on the measurement tube section at intervals in a length extension direction of the measurement tube section, andare communicated with the measurement tube section, the reflector assembly is arranged on the inner wall of the measurement tube section, and comprises a first reflector and a second reflector that have parabolic reflecting surfaces, the first reflector is used for reflecting ultrasonic wave sent by the first ultrasonic transducer to the second reflector through the inner wall of the measurement tube section, and the second reflector is used for reflecting the ultrasonic wave to the second ultrasonic transducer. The water meter measurement tube has the characteristic of high measurement accuracy; besides the reflector assembly, other reflecting surfaces serve as the inner wall of the measurement tube section, and are not processed and manufactured particularly.
Description
technical field [0001] The present application relates to the technical field of flow measurement, in particular, to a water meter measuring tube and an ultrasonic water meter. Background technique [0002] At present, small-diameter ultrasonic water meters mostly use through-beam, V-reflective or U-reflective ultrasonic measuring tube components. Although the above methods can also achieve measurement, they all have the disadvantage of insufficient measurement accuracy. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the embodiment of the present application is to provide a water meter measuring tube and an ultrasonic water meter, which can only install two reflectors, and use the inner wall of the measuring pipe section to reflect, so as to ensure that the water meter When the length of the measuring tube is limited, the effective sound path is maximized, and the measuring tube of the water meter ...
