Water gauge

Abstract

The invention discloses a water gauge. The water meter comprises a gauge outfit, a flux tube and an ultrasonic transducer. A transduction hole is formed in the flux tube, and the ultrasonic transducer is installed in the transduction hole. The gauge outfit is installed on the flux tube. The ultrasonic transducer is connected with the gauge outfit. A flow-splitting reflector is installed inside the flux tube and arranged corresponding to the ultrasonic transducer. The flow-splitting reflector comprises a splitter plate, and one end of the splitter plate is connected with an acoustic beam reflecting plate in an inclined mode. The ultrasonic transducer corresponds to the acoustic beam reflecting plate, and an acoustic beam emitted by the ultrasonic transducer is reflected on the acoustic beam reflecting plate. By the adoption of the water gauge, water flow in the flux tube can be split and neatened, the unstable state of the water flow is eliminated, differences in flow rates at all points of the same section are reduced, and therefore the accuracy of flow measurement is improved.

Description

technical field [0001] The invention belongs to the technical field of physical control and adjustment, and in particular relates to a water meter. Background technique [0002] The use of ultrasound to measure fluid flow velocity is a relatively widely used technology, and usually in the process of actually measuring the flow velocity, due to the fact that the liquid itself will have laminar flow, transition flow or turbulent flow when it flows in the pipeline, and it will be affected by the pipe wall. The liquid flow velocity at each point at the same section in the pipe is quite different, which will affect the accurate measurement of the liquid flow velocity to a certain extent, and the stability of the flow velocity will greatly affect the accuracy of the flow measurement. In some flow control precision requirements In high places, the unstable state of the flow rate should be eliminated to ensure accurate and reliable measurement of the water meter. Therefore, a measur...

[0002] The use of ultrasound to measure fluid flow velocity is a relatively widely used technology, and usually in the process of actually measuring the flow velocity, due to the fact that the liquid itself will have laminar flow, transition flow or turbulent flow when it flows in the pipeline, and it will be affected by the pipe wall. The liquid flow velocity at each point at the same section in the pipe is quite different, which will affect the accurate measurement of the liquid flow velocity to a certain extent, and the stability of the flow velocity will greatly affect the accuracy of the flow measurement. In some flow control precision requirements In high places, the unstable state of the flow rate should be eliminated to ensure accurate and reliable measurement of the water meter. Therefore, a measuring meter that can stably measure the flow rate of the fluid is needed.
