Description
Technical field
The present invention relates to a kind of flowmeter, relates more particularly to a kind of closed conduct ultrasonic flowmeter, belongs to fluid
Flow measurement equipment technical field.
Background technology
Due to seal and can not perspectivity, the flow of the fluid in closed conduct can not be known to the external world.As most simple
Single ground measuring method, the generally flow velocity of measurable fluid, the flow of fluid is then calculated according to the diameter of pipeline.Side herein
In method, common method is to use non-contact measurement, and the most frequently used instrument is exactly ultrasonic flowmeter.
The basic functional principle of ultrasonic flowmeter is as follows：Ultrasonic wave is just loaded with fluid stream when being propagated in the fluid of flowing
The information of speed, therefore, the flow velocity of fluid is detected by the ultrasonic wave can received, so as to be converted into flow.In the party
In method, ultrasonic pulse reaches another sensor through pipeline from a sensor, and when fluid does not flow, ping is with identical
Speed (velocity of sound, C) propagate in the two directions, if the fluid in pipeline has certain flow rate V (flow velocity be not equal to zero),
Ping along flow direction can be transmitted quicker, and the ping in reverse flow direction can be transmitted more slowly.In this way, following current
Transmission time can be slightly shorter, and the countercurrent time can slightly be grown.Certainly, length mentioned here or it is short be all when not flowed with fluid
Transmission time is Comparatively speaking.
And according to different detection methods, it is inclined that ultrasonic flowmeter can be divided into propagation speed differential method, Doppler method, wave beam again
The different types of ultrasonic flowmeter such as shifting method, Noise Method and correlation method.In all these ultrasonic flowmeters, with noise
Method principle and structure are most simple, are easy to measure and carry, and the cheap but degree of accuracy is relatively low, particularly suitable for accurate in flow measurement
Less demanding occasion is spent to use.
The most commonly used with the ultrasonic flowmeter of time difference principle in reality, it utilizes the difference and measured stream in propagation time
The relation of speed asks for flow velocity, and then obtains outflow.Such flowmeter has a variety of advantages, such as long lifespan, crushing are low, long-term fortune
Row stabilization, reliability height etc., also just because of these advantages, so as to have been widely used for urban water supply and sewerage, oil, chemical industry,
In the liquid meter field of the industries such as pharmacy, metallurgy and electric power.But such flowmeter there is also it is certain the defects of, such as measurement essence
Spend that low, measurement range is not high, this is also the technical problem for being currently needed for solving always.
For the foregoing reasons, because various ultrasonic flowmeters present in prior art still more or less lack in the presence of some
Fall into, and for novel ultrasonic low, there is also demand in practical application.Therefore, for developing a kind of new ultrasonic wave
