Problems solved by technology

When the direct transmission method or the reflection method is used, because the ultrasonic propagation direction crosses the water flow direction, what the ultrasonic wave actually detects is the flow velocity at each point of the water flow section, which can reflect the average velocity of the pipeline; when the parallel method is used, because the ultrasonic propagation direction is the same The water flow direction is parallel, and what the ultrasonic wave actually d

Abstract

The invention belongs to the technical field of metering appliances, and particularly discloses a straight-through reflecting type ultrasonic water meter and a heat meter flow sensor. The flow sensor comprises a sensor shell and is characterized in that the middle of the inner wall of the sensor shell is provided with a reflector platform; two ultrasonic energy converters are arranged on the inner wall of the sensor shell opposite to the reflector platform up and down; and a central perpendicular line of the reflector platform and central perpendicular lines of reflecting surfaces of the two ultrasonic energy converters are at the same plane. The straight-through reflecting type ultrasonic water meter and the heat meter flow sensor have the advantages of simple structure, safety, stability, accurate measurement, stable fluid flow state and small pressure loss.

Description

(1) Technical field [0001] The invention belongs to the technical field of measuring instruments, in particular to a straight-through reflective ultrasonic water meter and heat meter flow sensor. (2) Background technology [0002] At present, the existing ultrasonic water meters and heat meter flow sensors at home and abroad are generally composed of sensor housings, transducers, and reflectors. According to the arrangement of the channel, there are three main forms: direct transmission method, reflection method and parallel method. When the direct transmission method or the reflection method is used, because the ultrasonic propagation direction crosses the water flow direction, what the ultrasonic wave actually detects is the flow velocity at each point of the water flow section, which can reflect the average velocity of the pipeline; when the parallel method is used, because the ultrasonic propagation direction is the same The direction of the water flow is parallel, and ...
