Small-bore ultrasonic intelligent water meter

Abstract

The invention belongs to the technical field of a water meter and discloses a small-bore ultrasonic intelligent water meter. The small-bore ultrasonic intelligent water meter comprises a base meter body, wherein the base meter body is provided with a water inlet and a water outlet; the base meter body is provided with a first spherical expansion cavity and a second spherical expansion cavity; the tops of the first spherical expansion cavity and the second spherical expansion cavity are respectively provided with first ultrasonic energy converters, and the bottoms of the first spherical expansion cavity and the second spherical expansion cavity are respectively provided with a first ultrasonic reflection stand column and a second ultrasonic reflection stand column; the first ultrasonic energy converters are provided with first integrators; the top ends of the first spherical expansion cavity and the second spherical expansion cavity are respectively provided with a first reflection face and a second reflection face; and the first reflection face and the second reflection face are opposite to each other. According to the small-bore ultrasonic intelligent water meter, an ultrasonic technology is successively applied to the small-bore water meter, and the small-bore ultrasonic intelligent water meter can detect whether the water meter has a fault or not.

Description

technical field [0001] The invention belongs to the technical field of water meters and relates to an intelligent water meter, in particular to a small-diameter ultrasonic intelligent water meter. Background technique [0002] At present, most water meters are mechanical water meters, and only a few large-diameter water meters use ultrasonic methods. Among them, the mechanical water meter technology is relatively mature, the cost is low, and the performance is also very reliable. The small-diameter water meter basically adopts this scheme. The working principle of the mechanical water meter is to measure the volume of the flowing water through the water flow to push the impeller to rotate. This scheme has a simple structure and is easy to assemble. However, in practical applications, the user's water meter is generally installed on a parallel pipeline. During use, water hammer will occur in the pipeline due to other users or pressurized equipment. The mechanical water meter...

Problems solved by technology

However, in the field of small-caliber water meters, due to the small diameter of the base meter body and the large size of the ultrasonic transducer, the application is limited to a certain extent; Generally larger, these reasons limit the application of ultrasonic technology in the field of small-caliber water meters

Moreover, none of the existing water meters can effectively detect the faults of the water meter itself, whether there is water leakage and whether the flow calculation of the water meter is accurate, so that effective measures cannot be taken when the water meter initially leaks or the measurement is inaccurate. The occurrence of large water leakage accidents or large measurement deviations cause undue losses to plumbing users or supply units
