Embodiment Construction

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Such as Figure 6 , Figure 7 As shown, a high-precision ultrasonic metering channel includes a metering channel housing 7f, a partition sheet 7e, a blocking plate 7d, a channel bracket 7c, a metering module 7b and a channel cover 7a.

[0030] The separation sheet 7e is arranged in the metering channel housing 7f, and the stopper 7d is arranged at the opening above the metering channel housing 7f; the channel cover 7a is connected to the metering channel housing 7f, and the channel bracket 7c and the metering module 7b are arranged between the channel cover 7a and the metering channel. In the cavity formed by the channel housing 7f. The channel bracket 7c is an axisymmetric structure, connected to the metering channel housing 7f, corresponding to the position of the blocking plate 7d; there are two metering modules 7b...

Abstract

The invention discloses a high-precision ultrasonic metering channel which comprises a metering channel shell, a separation sheet, a blocking sheet, a channel support, metering modules and a channel cover. The separation sheet is arranged in the metering channel shell, and the blocking sheet is arranged at an opening in the upper part of the metering channel shell; the channel cover is connected with the metering channel shell and matched with an opening in the upper portion of the metering channel shell, and the channel support and the metering modules are arranged in a cavity formed by the channel cover and the metering channel shell. The channel support is of an axisymmetric structure, is connected with the metering channel shell and corresponds to the blocking sheet in position. The two metering modules are arranged on the left side and the right side of the symmetry axis of the channel support respectively. According to the invention, under the condition that one metering module is damaged, the other metering module which operates normally can be used for metering independently, so that the loss of commercial gas meters to manufacturers, gas companies and gas users due to metering channel faults is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic base meter structure, and in particular relates to a metering channel of an ultrasonic gas meter. [0002] technical background [0003] When the ultrasonic beam propagates in the fluid, the flow of the fluid will cause a slight change in the propagation time, and the change in the propagation time is proportional to the flow velocity of the fluid. Under the framework of this principle, the ultrasonic gas meter measurement modules currently on the market place a pair of ultrasonic transducers in the gas flow direction of the gas meter measurement channel (such as figure 1 As shown), the ultrasonic transducer transmits and receives at the same time (or alternately) during operation, and calculates the flow velocity of the gas in the metering channel according to the time difference between upstream and downstream receiving sound waves, and then obtains the instantaneous flow rate by multiplying t...
