The information of upper rate of flow of fluid is just carried during propagation.Therefore the flow velocity of fluid is detected by the ultrasonic wave can received, so as to
It is converted into flow.
Because ultrasonic signal has directionality, simply its sound wave row of the ultrasonic signal collection of one group of transducer group transmitting-receiving
One line of journey（A leptoprosopy in other words）Average speed；Recall by examining and determine the local line's average speed surveyed out and face
The scale parameter of mean flow rate, and then calculate outflow.Therefore, each instrument manufacturer is generally before the measurement body of table body
End adds various complicated rectifying devices or changes table shape even undergauge, so that the part into the fluid in measurement pipe body
Speed and the scale parameter of face average speed are constant, but due to before table pipeline change, when fluid is flowed through in measurement pipe body, stream
The scale parameter of Ti Zhong local lines average speed and face mean flow rate can change, then will be unable to calculate using original parameter
Correct flow.
The content of the invention
The purpose of this utility model is that solve above-mentioned the deficiencies in the prior art, there is provided one kind is simple in construction, does not change latus rectum
Table body, cost are cheap, measured value is accurate, contain the latus rectum ultrasonoscope for dividing chamber dividing plate stably, with strong antijamming capability
Table structure.
Technical scheme is used by the utility model solves its technical problem：
A kind of ultrasonic wave containing in the latus rectum ultrasonic meter structure for dividing chamber dividing plate, including measurement body and measurement body
Measuring part, it is characterised in that a point chamber dividing plate is axially arranged with the measurement pipe body, so that ultrasonic wave sound channel is with dividing chamber dividing plate phase
Intersect, it is described divide chamber dividing plate both sides respectively with measurement inboard wall of tube body be fixedly connected, it is described divide on chamber dividing plate correspond to ultrasonic wave sound channel
Path is perforated provided with ultrasonic wave sound channel, so as to divide chamber dividing plate to effectively eliminate eddy flow interference, current stabilization fluid, and passes through ultrasound
The ultrasonic signal for measuring part transmits along the perforation of ultrasonic wave sound channel, measures line average speed stable in measurement pipe body and face
The scale parameter of mean flow rate simultaneously calculates correct flow.
The utility model due to using said structure, have it is simple in construction, do not change that latus rectum table body, cost be cheap, measurement
Numerical value is accurate, stably, there is strong antijamming capability.
